Indonesia currently has six oil refineries and they are all operated by Pertamina, the national oil company of Indonesia.

Here are the top five refineries in Indonesia:

  • Dumai Refinery, officially known as Unit Pengolahan II Dumai
  • Plaju Refinery, officially known as  Unit Pengolahan III Plaju
  • Cilacap Refinery, officially known as Unit Pengolahan IV Cilacap
  • Balikpapan Refinery, officially known as Unit Pengolahan V Balikpapan
  • Balongan Refinery, officially known as Unit Pengolahan VI Balongan

Besides these five refineries, Pertamina operates a small 10,000 BOPD Kasim refinery in Sorong, West Papua.

With a total capacity to process 1,046,700 barrels of crude oil per day, all refineries in Indonesia are currently supplying about 50% of the domestic fuel needs.

In 2019, Indonesia imported 24.7 billion liters of fuel.

To meet its domestic fuel needs, Indonesia intends to produce all the fuels it needs by 2026. It hopes to increase the crude processing capacity to two million barrels per day in 2025 under the ambitious 17 billion dollar Refinery Development Master Plan (RDMP).

Based on the RDMP, the top five refineries will be upgraded to increase their capabilities and capacity. Currently, Pertamina is expanding and upgrading the Cilacap and Balikpapan refineries.

Pertamina also has a plan to build two new refineries: one in Tuban in East Java and one in Bontang in East Kalimantan.

The project to construct the 300,000 barrels of crude oil per day Tuban refinery is currently underway. It is expected to complete in 2026.

Here are the details of the top five refineries.

DUMAI REFINERY

Dumai refinery started operating in 1971 and it is located in Dumai in Sumatera.

The Dumai refinery is designed with a capacity to process 170,000 barrels of crude oil and it supplies Sumatera with fuels such as gasoline, aviation fuel, diesel fuel, kerosene, solvent, green coke, and LPG.

This refinery is unique as it produces the power it needs using the natural gas produced from the surrounding gas fields namely the Grissik field operated by ConocoPhillips, the fields in the Bentu block operated by Mega Energi Persada (PT EMP), and the Jambi Merang gas fields operated by Pertamina Hulu Energi Jambi Merang (PHE Jambi Merang).

By using the natural gas produced from these fields, the Dumai refinery can reduce its fuel cost by 40%.

PLAJU REFINERY

The Plaju refinery and petrochemical complex comprises two old refineries located in the Palembang area in South Sumatera: one in Plaju and another one in Sungei Gerong.

The refinery in Plaju is the oldest existing refinery in Indonesia. It was built in 1904 by BPM (Batavia Petroleum Maatschappy), a predecessor of Shell. Pertamina acquired this refinery from BPM in 1949.

The refinery at Sungei Gerong was built by SVPM (Standard Vacuum Petroleum Maatschappij) 1926. Pertamina acquired this refinery from Stanvac in 1970.

Pertamina integrated these two refineries in 1972 by constructing connecting pipelines and officially called them Unit Pengolahan III Plaju.

The integrated Plaju refinery and petrochemical complex has a combined refining capacity of 118,000 barrels per day. It processes crude oil and intermediate products to produce gasoline, kerosene, diesel fuel, the B20 biodiesel fuel, aviation fuel, and fuel oil.  

The types of gasoline it produces include the Premium, Pertalite, Pertamax, and Pertamax Racing.

The Plaju refinery also produces petrochemicals such as Polypropylene and PTA.

According to Pertamina, the Plaju refinery and petrochemical complex will see a new stand-alone 20,000 barrels per day “Green Refinery” in 2024 taking advantage of the locally produced crude palm oil (CPO). The new unit will produce green diesel fuel, green aviation fuel, green naphtha and green LPG.

CILACAP REFINERY

The Cilacap refinery is the largest and most integrated refinery and petrochemical complex in Indonesia. With its current refining capacity of 348,000 barrels of crude oil per day, it produces 34% of the total fuel production in Indonesia.

The Cilacap refinery was initially completed in 1976 with a capacity of processing 100,000 barrels of crude oil per day. However, as a strategic refinery due to its location being in Central Java, it has been revamped and expanded several times. 

Today, this Pertamina Unit IV refinery and petrochemical complex consists of three units:

  • Oil Refining Unit #1
  • Oil Refining Unit #2
  • Paraxylene Unit

Oil Refining Unit #1 was completed in 1976 with a capacity of processing 100,000 barrels of oil per day and it was designed to specifically handle crude oil from the Middle East.

This refining unit produces gasoline, lube oil, and asphalt. It underwent debottlenecking in 1998 to increase its refining capacity to 118,000 BOPD.

To meet the increasing demand for fuel, Oil Refining Unit #2 was completed in 1983 with a capacity of 200,000 BOPD. Its capacity was later increased to 230,000 BOPD in 1998.

This second unit is designed to handle both crude oil from the Middle East and Indonesia.

The Paraxylene Unit, completed in 1990, produces petrochemicals such as paraxylene, benzene, raffinate, and heavy aromatic. Some of these products are shipped to the Plaju refinery for further processing.

BALIKPAPAN REFINERY

The famous Balikpapan refinery was completed in 1922 by BPM (Bataafsche Petroleum Maatschappij), the predecessor of Royal Dutch Shell.  It was built to process the crude oil that BPM had discovered in Balikpapan in East Kalimantan.

The refinery was heavily damaged twice during World War II and subsequently restored. It was later acquired by  Pertamina from BPM in 1949.

The refinery has been expanded and upgraded several times to meet the increasing demand for fuel in the eastern part of Indonesia.

The Balikpapan refinery is the second-largest refinery in Indonesia. At its current crude oil processing capacity of 260,000 barrels, it processes 25% of the total crude oil intake and supplies about 15% of the fuel needs in Indonesia.  

Under the RMDP refinery expansion plan, it is set to become even bigger. It is currently undergoing a massive 5 billion dollar expansion which will increase its processing capacity from 260,000 barrels per day to 360,000 barrels per day.  

Besides increasing its processing capacity, the expansion project is also aimed to improve its crude flexibility and product quality. The refinery will have the capability to produce high-quality Euro V standard fuels.

The Balikpapan refinery expansion includes:

  • A residual fluid catalytic cracker (RFCC) unit with a design capacity of 90,000 barrels per stream per day (BPSD)
  • An LPG sulfur removal unit,
  • A propylene recovery unit
  • An 80,000 BPSD middle distillate hydrotreater.

The project will also upgrade the existing vacuum distillation unit (VDU), crude distillation unit (CDU), hydrocracker unit (HCU), and LPG recovery units to increase the production of Euro V gasoline, diesel fuel, and LPG by 100,000 BPD, 30,000 BPD and 930 tons respectively per day.

Included in the project is the expansion of the crude oil receiving capacity by adding:

  • A single-point mooring system and a pipeline end manifold, capable of handling crude carriers with 320,000 deadweight tonnage (DWT).
  • A 20-inch onshore pipeline from Lawe-Lawe terminal to Panajam terminal.
  • A 52-inch subsea pipeline from the Panajam terminal to the refinery.
  • Two new crude oil storage tanks with a capacity of 100 million barrels.

Balongan Refinery

Located in Indramayu, West Java, the Balongan refinery was completed in 1994. It was revamped in 2003 to increase its processing capacity to 130,000 barrels of crude oil per day.

The Balongan refinery and petrochemical complex is designed to process crude oil from the Duri and Minas fields.

It produces a variety of fuels such as Premium, Pertamax, Pertamax Plus, diesel fuel, kerosene, and LPG. It also produces petrochemicals such as propylene.

This Unit VI refinery of Pertamina is a strategic and vital refinery to Indonesia as it supplies the fuel needs of the nation’s capital city of Jakarta and West Java.

The Balongan refinery prides itself for being the refinery that applies eco-friendly technology and that processes residue into high-quality products.

The refinery experienced a fire incident on 29th March 2021. Four of its storage tanks caught fire.

Kasim Refinery

The 10,000 BPD Kasim refinery is the newest but the smallest refinery of Pertamina.

Located in Sorong in West Papua, Kasim refinery was completed in 1997 to meet the needs for fuels in the most eastern part of Indonesia. It takes advantage of processing the crude oil produced from the nearby fields of Walio and Salawati.


This Pertamina Unit VII refinery is currently operating below its design capacity of 10,000 BOPD. This is due to the declining oil production from the two oil fields.

To make the plant economical to operate, Pertamina will need to increase the crude supply by bringing in crude oil via oil tankers. To do so, it will need to construct four 110,000 barrel storage tanks.

Currently, the Kasim refinery is supplying less than 15% of the fuel needed in Papua and Maluku. It is hoped that Kasim can process 50,000 BOPD in the future.

The Old Dutch Oil Companies in Indonesia

The Balikpapan Refinery – Photo courtesy of Tropenmuseum

Since the early 1900s, with oil discoveries in Sumatera in 1885, Java in 1887, and Kalimantan in 1891, Indonesia has been recognized as an important oil-producing country outside America.

By 1900 there were already 18 oil companies operating in Indonesia. It is interesting to note that only companies registered in Nederland and managed by the Dutch could operate in Indonesia at that time.  The reason for this was up until World War II, Indonesia was under the administration of the Netherlands East Indies (NEI).

These old Dutch oil companies played important roles in putting Indonesia on the world map as a significant producer of crude oil and fuels. They discovered and developed many oilfields in Indonesia, and even built refineries in Sumatera, Java, and Borneo. By 1938, oil production had reached 140,000 barrels per day.

Oil well drilling in Pangkalan Susu, Sumatera, in 1916 by KNPM.

By 1945, the year when Indonesia declared its independence, due to acquisitions and mergers, the number of oil companies had reduced to just four: BPM (Bataafsche Petroleum Maatschappij), NIAM (Nederlands Indische Aardolie Maatschappij), STANVAC, and CALTEX.

Stanvac and Caltex which were owned by their American parent companies started as Dutch-registered companies.

After 1965, when Pertamina acquired BPM, all the oil companies with Dutch names no longer existed. Nevertheless, their names appeared in many old and new articles and are often cited in research papers.

Since the names of the old Dutch oil companies in Indonesia consisted of long Dutch words, they were often written in their acronyms.

Here is the glossary of the acronyms of some of the old Dutch oil companies that operated in Indonesia in the past. 

BPM – Bataafsche Petroleum Maatschappij

DPM – Doordsche Petroleum Maatschappij

KNPM – Koninklijke Nederlandsche Petroleum Maatschappij

NIAM – Nederlands Indische Aardolie Maatschappij

SPPM – Sumatera Palembang Petroleum Maatschappij

MEPM – Muara Enim Petroleum Maatschappij

NNGPM – Nederlandsche Nieuw Guinea Petroleum Maatschappij

SVPM – Standard Vacuum Petroleum Maatstchappij

SVTM – Standard Vacuum Tankvaart Maatschappij

NKPM – Nederlandsche Koloniale Petroleum Maatschappij

NPPM – Nederlandsche Pacific Petroleum Maatschappij 

SMOB – Steenkolen Maatschappij Oost Borneo

NIIHM – Nederlandch Indisch Industrie en Handel Maatschappij

The Three Big Oil Companies in Indonesia before 1945

Sungei Gerong Refinery in South Sumatera in 1926

The first oil exploration in Indonesia started not long after Colonel Drake successfully drilled the first oil discovery well in Pennsylvania in the United States in 1859.

By 1869, Dutch businessmen in Indonesia, known as the Netherlands East Indies at that time, had noticed and recorded 53 oil seepage locations in Sumatera, Java, and Kalimantan.

Then the first oil well drilling in Indonesia took place in 1871 in West Java.

However, commercial discoveries were made only several years later when a Dutch businessman drilled successful exploration wells in Pangkalan Brandan in North Sumatera in 1885 and Sanga-Sanga in East Kalimantan in 1892.

These two discoveries caught the attention of the world and put Indonesia on the map as one of the countries with interesting oil potentials.

By 1900 there were already 18 oil companies searching for oil in the Netherlands East Indies (NEI). All these companies were either Dutch companies or non-Dutch companies registered in Nederland. The high level of activities resulted in significant oil discoveries in the early 1900s.

Following the oil discoveries, refineries were built in Pangkalan Brandan in North Sumatera in 1892, Sungei Gerong in South Sumatera in 1926, Balikpapan in East Kalimantan in 1922. By 1940, there were already seven refineries in NEI: three in Sumatera, three in Java, and one in Kalimantan.

In 1938, the daily crude oil production was about 140,000 BOPD and in 1953 it was about 190,000 BOPD.

The high level of oil production and refining activities from 1900 to 1940 made Indonesia well-known as one of the world’s significant crude oil producers and refined product suppliers at that time. In fact, Indonesia was so well-known for its oil it became involved in World War II.

Recognized as a significant oil producer, Indonesia was invited to become a member of OPEC 1962.

The three oil companies that produced about 90% of all the petroleum in Indonesia during the Dutch colonial period are:

  • BPM – Bataafsche Petroleum Maatschappij
  • STANVAC – Standard Vacuum Oil Company
  • CALTEX

Here are the amazing stories of these three big oil companies operating in Indonesia before 1945.


BPM

BPM is Bataafsche Petroleum Maatschappij, also called the Batavian Oil Company. Batavia, which is Jakarta today, was the center of the NEI government.

BPM was established in 1907 by KNPM (Koninklijke Nederlandsche Petroleum Maatschappij) also known as Royal Dutch Petroleum Company and Shell Trading and Transport Company to explore and produce oil in the Netherlands East Indies.

Royal Dutch Petroleum Company owned 60% and Shell owned 40% of BPM.

Before BPM was set up, there were already as many as 18 oil companies operating in the Netherlands East Indies (NEI) from North Sumatera, Java, Borneo, and all the way to Papua.

BPM quickly took over almost all of these companies and dominated the oil industry in Indonesia. By 1920, it had controlled more than 95% of crude oil production in Indonesia.

In 1921, as the government of the Netherlands East Indies wanted to take part in the booming oil business in Indonesia, NEI and BPM formed another company called NIAM (Nederlands Indische Aardolie Maatschappij).

Many big changes took place in the oil industry after Indonesia declared its independence in 1945. The first big change was the takeover by the government of Indonesia the NEI’s 50% ownership in NIAM.

This marked the beginning of an Indonesian government-owned oil company. It also started a working relationship between BPM and the government of Indonesia. With this relationship, BPM managed to extend its activities in Indonesia until 1965.

In 1965, BPM sold all its assets in Indonesia to the Indonesian state-owned company PN Permina for US$110 Million. Permina later became Pertamina.

BPM operations in Indonesia were extensive. They stretched from the western part of Indonesia to the eastern part of Indonesia.

Here are the operations of BPM in various parts of Indonesia.

BPM In Borneo

In 1907, right after it was formed, BPM acquired the oil fields and refinery in Balikpapan from Mathilda company. It also acquired the oil fields in Sanga Sanga and Tarakan which had been discovered previously by KNPM (Koninklijke Nederlandsche Petroleum Maatschappij).

BPM expanded its exploration and production aggressively in East Borneo and continued to discover several other fields in these areas.

On the small island of Tarakan, BPM drilled 700 oil wells and built a refinery.

Production continued to increase and in the 1920s the Tarakan wells produced about 18,000 BOPD, a third of the total oil production in the whole Dutch East Indies.

BPM in North Sumatera

BPM acquired from KNPM the oil fields and the refinery located at Pangkalan Brandan. BPM also took over the operations of the oil tanking and the oil export facilities at Pangkalan Susu. Pangkalan Susu was the first oil-exporting port in Indonesia.

BPM in Java

In Java, BPM acquired the oil assets of DPM (Doordsche Petroleum Maatschappij), a Dutch oil company established by Adriaan Stoop in 1887.

DPM had discovered and operated the Kruka Field and the Djabakota Field near Surabaya in East Java. DPM also had built the oil refinery in Wonokromo. Completed in 1893, this was the first oil refinery in Indonesia.

By acquiring DPM, BPM also became the owner of some thirty oil fields in East Java including another refinery located in Cepu which was built in 1894.

BPM In South Sumatera

In South Sumatera, BPM took over SPPM (Sumatera Palembang Petroleum Maatschappij). SPPM had been operating the oil fields in its concessions in Banyuasin and Jambi.

BPM also acquired the oil assets of MEPM (Muara Enim Petroleum Maatschappij). MEPM had discovered the Muara Enim field and built the Plaju Refinery.

BPM In Irian Jaya

In 1935 BPM expanded its search for oil into Irian Jaya. For this venture, along with other partners, BPM formed a joint venture company named NNGPM (Nederlandsche Nieuw Guinea Petroleum Maatschappij) with exploration rights for 25 years.

By 1938 they had discovered the Klamono oil field. followed by Wasian, Mogoi, and Sele fields.

However, for commercial reasons, these fields were not developed.

STANVAC

STANVAC – Standard Vacuum Oil Company – started as NKPM (Nederlandsche Koloniale Petroleum Maatschappij) in 1912. NKPM was set up in Nederland by the American company Standard Oil of New Jersey so it could explore for oil in Indonesia.

Since Indonesia was under the control of the Netherlands East Indies at that time, Jersey Standards had to set up NKPM as a Dutch-registered and Dutch-managed company with headquarters located in The Hague.

NKPM began to make exploration in Java and South Sumatera in 1914.

It was in South Sumatera NKPM found its liquid gold. Operating from the city of Palembang, it discovered the Petak field in 1914, the Trembule field, and the huge Talang Akar field in 1921. These discoveries prompted NKPM to construct the famous Sungai Gerong oil refinery.

In 1922 NKPM changed its name to SVPM (Standard-Vacuum Petroleum Maatschappij).

It also constructed the 130 Km long pipeline from Pendopo area to Sungai Gerong to bring the crude oil from the prolific Talang Akar field to the refinery.

The Sungai Gerong refinery began operating in 1926 and became the largest and important oil refinery in South East Asia.

It was so important that the refinery was occupied by Japanese forces from 1942 to 1945 during World War II.

To meet the increasing demands for petroleum products in Africa and the Asia Pacific, Standard Oil Company of New Jersey and SOCONY (Standard Oil Company of New York) jointly created STANVAC (Standard Vacuum Oil Company) in 1933.

This was a synergistic partnership as Standard Oil Company of New Jersey had the oil production capacity and SONONY had the marketing facility.

The newly created Stanvac in the Netherlands East Indies consisted of three companies: Standard Vacuum Petroleum Maatschappij (SVPM), the Standard Vacuum Sales Company (SVSC), and the Standard Vacuum Tankvaart Maatschappij (SVTM).

Stanvac took over all the assets of SVPM in Indonesia and became a full-fledged oil company involved in oil exploration and production, refining, transportation, and distribution in more than 50 countries.

However, Stanvac continued to operate under its Dutch company name – SVPM – in the NEI.

Stanvac produced oil from many fields in South Sumatera. The notable ones were Talang Akar, Djirak, Benakat, Radja fields.   

In 1934, Stanvac expanded its operations to Central Sumatera.  Here it discovered and developed the well-known Lirik field and later the Binio field.

Things began to change after World War II and the declaration of independence of Indonesia.

It was after the declaration of independence by Indonesia in 1945, to distance itself from its Dutch connection, Stanvac began calling itself  Stanvac Indonesia as its company name to show its American origin.

In so doing, Stanvac was able to keep its assets and continue to operate in the newly independent Indonesia.

In 1960, as Indonesia wanted to have more control of the oil operation and business, it introduced the 1960 Oil Law which stated that all foreign oil companies must operate as a contractor for the Indonesian government.

On 24 September 1963, Stanvac signed the “Contract of Work” agreement with Indonesia’s Pertambangan Minjak Nasional (Permina).

The contract allowed Stanvac to continue to have full control of its oil exploration and production operations in Indonesia. Under this agreement, Stanvac must sell its refinery within ten to fifteen years.

However, Stanvac had to sell its Sungai Gerong refinery to Pertamina in 1969.

Stanvac Indonesia continued to operate its oil fields until finally, it left Indonesia in 1995 when it sold all its assets to Medco Energi for 88 million USD.

CALTEX

CALTEX was established in 1936 by Standard of California and Texaco to explore and produce oil in Indonesia and to expand its oil business in the Asia Pacific.

Earlier in 1924, The Standard of California had sent its team of geologists to Indonesia.

To operate in the Netherlands East Indies at that time, Caltex must obtain oil concessions from the government of NEI (Nederlands East India) who was the ruler of Indonesia at that time. To do so, Caltex established NPPM (Nederlandsche Pacific Petroleum Maatschappij), a Nederland registered company with its headquarters located in The Hague. Also, the company must be run by Dutch nationals.

In the same year, Caltex received its first oil concession in the Rimba area which is now known as the Rokan Block in Central Sumatera.

Soon after that Caltex began to find oil, but it was in 1941 that  Caltex discovered the huge Duri field. Due to the high pour point of its low gravity crude oil, it was necessary to use steam-flood to drive out the oil. Due to the success of the steam flood method, the Duri field became known as one of the largest steam-flood projects in the world. In spite of the huge challenges to produce the field, it has produced more than 2.64 billion barrels of oil so far.

Several years later Caltex went on to discover another giant oil field, The Minas field.

The story of the Minas field discovery is very interesting. In 1940, at the beginning of World War II, Caltex had started the drilling of its exploration well in the Minas area. However, before the drilling was completed, Caltex had to abandon the drilling as the Japanese army was coming to occupy the area and to take over the oil facilities.

The Japanese army engineers resumed the drilling of the well in 1943 and discovered oil when it drilled down to 2600 feet deep.

At the end of the war, Caltex regained control of its oil assets and continued to investigate the Minas field. After drilling several additional wells, Caltex confirmed the discovery of the huge Minas oil field.

Caltex went on to discover many smaller oil fields in its concession area.

By the late 1950s, Caltex became one of the largest oil producers in Indonesia.  At its peak in 1973, Caltex produced about 1 million BOPD from the Duri, the Minas, and about 80 smaller oil fields. Caltex holds the record of having the highest daily crude oil production rate in Indonesia.

Caltex completed the construction of a crude oil export terminal in Dumai in 1958.

Caltex signed a work contract agreement with Indonesia in 1961 giving it the right to continue to operate the Rokan block until 2001. Later on, Caltex managed to obtain a work contract extension to operate the block for another 20 years until 2021.

The two owners of CALTEX, Chevron, and Texaco merged in 2001 to become ChevronTexaco Corporation. Later on, in 2005, ChevronTexaco Corporation dropped the name Texaco and renamed the company as Chevron Corporation.

Following the name change of its parent company, Caltex in Indonesia which was initially incorporated as PT Caltex Pacific Indonesia changed its name to PT Chevron Pacific Indonesia.

By 2008, Chevron Pacific Indonesia had produced 11 billion barrels of crude oil from the extremely prolific Rokan block.

Although the Rokan block has been producing oil for more than 80 years, it still has 2 billion barrels of estimated producible reserves. It is considered as an important block in Indonesia’s ambition to increase the daily oil production in Indonesia to one million barrels by 2030.

Although the name Caltex disappeared in Indonesia after the name change, the Caltex petroleum brand is still alive in many countries in the Asia Pacific.

Epilogue

These three companies of the past were great companies to work for. Since most of their oilfields were located in the middle of a jungle, the companies provided good and well-rounded facilities – schools, clinics, cafeterias, places for worship, sports, and entertainment – to their employees and their families.

Many people and children of those who had worked for these companies have fond and colorful memories of the companies.

To me, the one that is the most interesting is BPM.

The joint venture of Royal Dutch Petroleum Company and Shell Trading and Transport Company that formed BPM – Bataafsche Petroleum Maatschappij – in Indonesia in 1907 sowed the seed that eventually grew into the current giant Shell Oil Company.

Also, BPM had a role in the rise of Pertamina when Pertamina took over all the assets of BPM in 1965.

Fifty years ago, Union Oil of California (UNOCAL) along with its partner, INPEX, discovered the giant offshore oil field Attaka in East Kalimantan.

General Soeharto, the president of Indonesia at that time, then inaugurated the Attaka field and the Santan terminal on 22 January 1973.

In the early days of Attaka and the Santan terminal, there were many workers from the US and UK. Over time, they were gradually replaced by Indonesian workers.

Unocal operated the oil field for 25 years from its East Kalimantan headquarters located in Balikpapan. The Attaka field was subsequently acquired and operated by Chevron, and then by Pertamina Hulu Kalimantan Timur beginning on 25 October 2018.

At 50 years old, the field is still producing today.

Thousands of oil people – expatriates from many nations and Indonesians from every region – have visited and worked in the offshore facilities and the onshore Santan terminal including me.

I worked in the Attaka field as “Production Foreman” in 1980. I hope you like this snippet of the history of Attaka and the Santan terminal.

The SKK Migas

The SKK Migas of Indonesia has also been very proactive in its roles as the supervisor of the production sharing contractors to facilitate their exploration and production activities.

With the vision to increase the oil production in Indonesia to one million barrels per day by 2030, SKK Migas instituted the Integrated Operation Center (IOC) and the One Door Service Policy (ODSP) in 2019.

The Integrated Operation Center (IOC)

 SKK Migas launched the Integrated Operation Center (IOC) in 2019. With the IOC, SKK Migas now has online and realtime access to information and data related to the exploration, drilling and production activities of the production sharing contractors in all work areas.

The  IOC allows SKK Migas to monitor the daily field activities of all operators, understand the field situations and make prompt recommendations.

The objectives of SKK Migas in establishing the OIC are to keep the oil and gas operations go smoothly and achieve the production targets.

Currently here is the information that is being monitored by the Integrated Operation Center:

  • Oil and gas production (Production Dashboard)
  • Oil and gas lifting (Oil and Gas Lifting Dashboard)
  • Stock Management (Stock Management Dashboard)
  • Plant Operation (Plant Information Management System – PIMS)
  • Facility Maintenance
  • Project Progress
  • Vessel tracking (Vessel Tracking Information System – VTIS)
  • Real-Time Drilling Operation
  • Emergency responses (Emergency Response Center – ERC)

The One Door Service Policy (ODSP)

SKK Migas also introduced One Door Service Policy (ODSP) in 2019. Through ODSP, the applications of all the permits related to exploration, drilling, field development, and production can be processed in one place.

SKK Migas will work with and support all the production sharing contractors in preparing the required documents and submitting the applications to obtain the various permits they need.

This is a very significant service because of the various types of permits that oil operators must apply. With this one-door policy, SKK Migas is hopeful that the various permits can be obtained promptly, and the oil and gas exploration and production targets can be achieved.

The One Door Service Policy consists of four work-groups that will help the production sharing contractors deal with the following type of permits:

  • Permits related to land acquisition and use 
  • Permits related to the environment, safety and security
  • Permits related to the use of resources and infrastructure
  • Permits related to the use of materials and human resources from outside Indonesia.

Several exploration and production targets were exceeded in 2019 and SKK Migas is hopeful the new 2020 targets can be achieved also by the end of the year.

Balikpapan, located in East Kalimantan, is the most well known and interesting oil town in Indonesia, and possibly in the world. It is at the center of oil and gas exploration and production activities that have been taking place in East Kalimantan since 1897 when the first oil well was drilled in Balikpapan. It is also the battleground of two fierce battles during World War II. It is set to become even more well known with the announcement of the relocation of the capital city of Indonesia from Jakarta to East Kalimantan.

Here are the interesting facts about Balikpapan.

The First Oil Discovery At Balikpapan

Oil was discovered in Balikpapan in 1897 when Jacobus Hubertus Menten, a Dutch mining engineer observed oil seepages in the area. With the help from Sir Marcus Samuel from Shell Transport and Trading Ltd, they drilled the famous Well Mathilda B-1 on 10 February 1897. The well was drilled to 222 Meter and it flowed initially at 184 barrels per day. This oil discovery in Balikpapan took place 38 years after Sir Edwin Drake drilled the world’s first oil well in America.

This picture shows the Mathilda B-1, the first well drilled in Balikpapan. The picture was taken by Chaz Tumbelaka.

With the discovery, Jacobus Hubertus Menten and Sir Marcus Samuel formed Nederlandsch Indisch Industrie en Handel Maatschappij (NIIHM), and it continued to discover other oil fields away from Balikpapan. 10 February 1897 is considered the birth date of Balikpapan.

The Balikpapan Refinery

This image has an empty alt attribute; its file name is collectie_tropenmuseum_gezicht_over_de_baai_van_balikpapan_met_olietanks_en_steigers_van_de_bataafsche_petroleum_maatschappij_bpm_tmnr_60018714-1.jpg

To process the crude oil from the surrounding area and to meet the needs for fuel, the oil refinery of Balikpapan was completed in 1922 by BPM (Bataafsche Petroleum Maatschappij) which was a subsidiary of Royal Dutch Shell. The Balikpapan refinery was damaged in 1942 when the Japanese army invaded Balikpapan. The refinery was controlled by the Japanese army in 1942-1945. BPM regained control of the refinery after the Allied forces ended the Japanese occupation of Balikpapan in 1945.

Several years later, Pertamina gained control of the refinery in 1949. The refinery has been expanded and upgraded several times to meet the increasing demand for fuel in the eastern part of Indonesia.

As one of the largest refineries in Indonesia, it is set to become even bigger. It is currently undergoing a large 4-billion-dollar expansion which will increase its processing capacity from 260,000 barrels per day to 360,000 barrels per day when it is completed in 2021. The refinery will have the capability to produce high-quality Euro V standard fuels.

The Discovery of Giant Oil and Gas Fields

Balikpapan experienced its biggest boom when several large international oil companies came to town after the production sharing contract scheme was introduced by Indonesia in 1966.

Balikpapan was the base of Union Oil of California (Unocal), Total and Roy M. Huffington Incorporated (Huffco) during their exploration and production operations in East Kalimantan where they discovered several giant oil and gas fields.

Pertamina has a huge presence in Balikpapan since 1949 when it took over the oilfields and the refinery which were previously operated by BPM (Bataafsche Petroleum Maatschappij), a subsidiary of Royal Dutch Shell.

Operated from Balikpapan, Unocal in partnership with Japex discovered the giant offshore oil field of Attaka in 1970. It also discovered the offshore Sepinggan field and the Yakin field both of which are clearly visible from the hills at Balikpapan. In 1996, Unocal discovered and developed the West Seno field which is the first deepwater oil field in Indonesia.

Total with its partner, Inpex, acquired the Mahakam Block in 1966. They discovered several giant offshore oil and gas fields: Handil, Peciko, Tambora, Bekapai, South Mahakam, Sisi-Nubi, and Tunu.

Huffco discovered the giant onshore Badak gas field in 1970 in East Kalimantan. The discovery of the giant Badak gas field had a huge influence on the course of oil and gas development in East Kalimantan. It prompted Huffco and Pertamina of Indonesia to build an LNG plant making it possible to export the gas.

Besides the Badak field, Huffco subsequently discovered the Nilam, Pamaguan, Semberah, Mutiara, Beras, and Lempake fields.

Huffco later became known as VICO Indonesia (Virginia Indonesia Company) in 1990 after Mr. Roy M. Huffinton sold the company.

After the introduction of the production sharing contract scheme  (PSC) in 1966, and with the discovery of several giant oil and fields in East Kalimantan and in other parts of Indonesia, crude oil production in Indonesia increased from 500,000 BOPD to 1,650,000 BOPD at its peak in 1977.

The Badak LNG Plant in Bontang

The LNG plant known as the Badak LNG was completed in 1977. Located in Bontang, besides processing the gas produced by Huffco from the Badak field, the Badak LNG plant also processes gas produced from the fields operated by Unocal and Total located in East Kalimantan. Up until the completion of the LNG plant, most of the associated gas produced by Unocal and Total were flared.

The Badak LNG plant initially comprised of two trains. Over the years, with new field discoveries, six additional trains were constructed. With 22.5 million tons per year LNG production capacity, it is one of the largest LNG plants in the world.

As of 16 September 2019, Badak LNG has delivered 9445 LNG cargoes to countries such as Japan, Taiwan, Korea, China, the USA, Russia, and India. 

The Fierce Battlefield during World War II Twice

Being rich in oil and having a refinery, Balikpapan was so vital that it became a battlefield twice during World War II.

The Battle of Balikpapan in 1942

During World War II, in order to control the supply of fuel, Japan invaded Balikpapan in 1942. The Dutch garrison resisted the invasion but eventually was defeated by the much bigger Japanese forces. The refinery was partially destroyed during the invasion. Japanese forces took control of Balikpapan, oil production and the refinery from 1942 to 1945.

The Battle of Balikpapan in 1945

To regain control of Balikpapan and the oil supply, the Allied forces directed by General Douglas McArthur and spearheaded by the Australian 7th Division invaded Balikpapan on 25 June 1945. After 3 weeks of fierce fighting and heavy bombing, the Japanese soldiers in Balikpapan finally surrendered on 21 July 1945. Many Japanese soldiers fought to the end in the battle. There is a Japanese cemetery hidden among the hills in Balikpapan.

The Coal Boom of Balikpapan in the 1990s

Balikpapan experienced another economic boom when it became the center of the booming coal production in East Kalimantan beginning in the 1990s.

The Balikpapan Coal Terminal completed in 1995 is one of the biggest coal terminals in Indonesia. It has a throughput capacity of 15 million tons of coal annually.

Will Balikpapan continue to boom?

Since the discovery of the first oil well in Balikpapan in 1897, Balikpapan has seen several booms in the last 120 years. It has grown from a small fishing village to become a city with a population of 850,000 today.

On 26 August 2019, the President of Indonesia, Joko Widodo, announced that Indonesia will relocate its capital city from Jakarta to East Kalimantan. As the main gateway to East Kalimantan, Balikpapan will be the center of activities during the construction of a new capital of Indonesia. So, Balikpapan will likely continue to boom.

Finally, Balikpapan indeed is a very interesting town. As an oil and coal mining town, it has been voted several times as the most liveable city in Indonesia.  Thousands of oil people from around the world have worked and lived here. Many children of international expatriates and Indonesian oil professionals from Java, Sumatera and other parts of Indonesia grew up in Balikpapan. Most of them have fond memories of Balikpapan.

Many sons and daughters of the first-generation Indonesian oil professionals follow the footsteps of their parents to work for oil companies in Balikpapan. There is a saying in Balikpapan whoever has drunk the water of Balikpapan will surely return. The writer of this article lived and worked for Unocal in Balikpapan from 1976 to 1980, and he has returned to visit this interesting place many times.

Pertamina has completed the construction of the 67 km gas pipeline supplying gas to its Unit II Refinery in Dumai. With the commissioning of the 24-inch pipeline on 14 April 2019, the fuel needed to operate the refinery is now supplied by the gas produced from the nearby gas fields.

The gas comes from the following three blocks:

  1. The prolific Grissik field located in the Corridor Block which is operated by ConocoPhillips. The Grissik field produced more than 900 MMSCF of gas per day in 2018. With an area of 2258 square kilometers, the Corridor Block is one of the largest gas blocks in Indonesia. Other very large gas blocks are the Tangguh and the Mahakam blocks.
  2. The fields located in the Bentu Block which is managed by PT Mega Energi Persada (PT EMP). The Bentu Block is located near the city of Pekanbaru. PT EMP also supplies its gas to Indonesia’s state power company (PLN) and Riau Andalan Pulp and Paper (RAPP).
  3. The oil and gas fields located in the Jambi Merang Block which is now operated by Pertamina Hulu Energi Jambi Merang (PHE Jambi Merang). PHE Jambi Merang acquired the block from the Joint Operating Body Pertamina-Talisman Jambi Merang on 9 February 2019.

In the past, the refinery used the fuel oil, Naptha and fuel gas it produced internally to meet the fuel needs of the refinery.

The project has brought significant economic benefits to both the gas producers and the refinery. In using the gas, the refinery is able to reduce its fuel costs by 40%.
