In 2019, the average daily crude oil production in Indonesia was 746,000 barrels.

Here are the eight largest crude oil lifting terminals in Indonesia in 2019 according to SKK Migas of Indonesia.

  1. WIDURI MARINE TERMINAL

Widuri Marine Terminal is operated by Pertamina Hulu Energi OSES which operates the oil fields located in the Offshore South East Sumatera contract area.

The South East Sumatera contract area was initially awarded to IIAPCO in 1968. Many big oil fields were discovered in this block such as Banuwati, Cinta, Intan, Widuri and Zelda.

Crude oil produced from these fields were stored in the Lentera Bangsa FSO – a floating, storage, and offloading vessel – and then offloaded into oil tankers.

The operatorship of this contract area changed hands many times during its 50 years of operation. Previous operators include IIAPCO, Maxus, Repsol, and CNOOC.

The average daily crude oil lifting volume of the Widuri Marine Terminal was 8501 BOPD.

  1. SENORO MARINE TERMINAL

Senoro Marine Terminal is operated by JOB Pertamina  Medco Tomori Sulawesi which is a joint operating body consisting of Pertamina Hulu Energi, Medco E&P and Tomori E&P.

JOB Pertamina Medco Tomori Sulawesi operating in the Tomori-Toili Block located in Central Sulawesi produces gas and condensate from the Senoro gas field and crude oil from the Tiaka oil field.

The gas from the Senoro field is processed into LNG by the Donggi-Senoro LNG plant which started operation in August 2015.

The average daily lifting volume at Senoro Marine Terminal was 14,857 BOPD

  1. TUBAN MARINE TERMINAL

Tuban Marine Terminal located in East Java is operated by PT Pertamina EP. The terminal handles the lifting of crude oil that Pertamina EP produces from the Tuban block. Before 29 February 2018, the Tuban block was operated under Joint Operating Body (JOB) Pertamina Petrochina East Java.

PT Pertamina EP, established on 17 September 2005, came under the supervision of BPMIGAS on 17 September 2005. BPMIGAS became SKK Migas on 13 November 2012.

On average, 16358 BOPD was lifted at the Tuban Marine Terminal.

  1. ARDJUNA TERMINAL

The Ardjuna oil terminal is operated by Pertamina Hulu Energi ONWJ which operates the oil and gas fields located in the Offshore North West Java work area.

The huge Ardjuna oil field was initially discovered by ARCO after it signed the PSC contract in 1971. ARCO later became BP West Java.  Pertamina Hulu Energi ONWJ became the operator of the Ardjuna field in July 2009.

The average crude oil lifting volume from the Ardjuna terminal was 25626 BOPD.

  1. SENIPAH MARINE TERMINAL

Senipah Marine terminal is operated by Pertamina Hulu Mahakam. The terminal was previously operated by Total Indonesie who discovered several big oil and gas fields – Bekapai, Handil, Tunu, Peciko, Sisi, Tunu –  in the Offshore Mahakam block.

On average, 31539 BOPD was lifted at The Senipah Marine terminal.

  1. RU PP7

The RU PP7 terminal is located in the Riau province in Sumatera and operated by Chevron Pacific Indonesia.

The average daily lifting volume at RU PP7 Terminal was 62,337 BOPD.

  1. DUMAI TERMINAL

The Dumai terminal is located in the Riau province in Sumatera and operated by Chevron Pacific Indonesia who holds the operatorship of the prolific Rokan PSC which will soon expire in 2021.

Chevron Pacific Indonesia, also known as CPI, discovered two super-giant oilfields: the Duri field in 1941 and Minas in 1944. Subsequently, CPI continued to discover many smaller oil fields in the Rokan work area.

Due to its low gravity oil, the Duri field underwent steam flooding in 1985 to enhance the recovery of its heavy oil. The Duri field steam flood project is one of the largest in the world.

The average daily lifting volume at the Dumai Terminal was 116,555 BOPD.

  1. BANYU URIP MARINE TERMINAL

At an average daily crude oil lifting volume of 200, 937 barrels, the Banyu Urip Marine Terminal is currently the top crude oil lifting terminal in Indonesia. It handles the lifting of the crude oil produced by Mobil Cepu from the onshore Banyu Urip field located in the Cepu Block contract area.

After the crude is processed in the central processing facilities (CPF) located at the center of the oil field, the oil is transported through a 72 KM long pipeline to the coast of Tuban, and then through a 23 KM long subsea pipeline to the FSO (Floating, Storage and Offloading) vessel. The FSO is named FSO Gagak Rimang.

The crude oil from the Banyu Urip field is lifted by oil tankers from FSO Gagak Rimang for transport to domestic and international refineries. The FSO has storage capacity for 2 million barrels of crude oil.

Since 1966 when Indonesia began offering production sharing contracts (PSC) for international companies to explore and produce oil and gas in Indonesia, many giant and super-giant oil and gas fields were discovered.

Giant fields are those with estimated ultimate recoverable reserves (EUR) of 500 million barrels of oil or gas equivalent (MMBOE) and super giant oil fields are those holding an equivalent of 5.5 billion barrels of oil reserves.

Here are the ten giant offshore oil and gas fields in Indonesia discovered between 1966 and 2000.

1. Abadi Field

Abadi is a giant gas field discovered by Inpex in 2000 in the Masela contract area in the Arafura Sea. The Abadi field has an estimated ultimate recovery (EUR) of 768 MMBOE and it is located 93 miles offshore from the province of Maluku in the eastern part of Indonesia.

Originally the field would be developed using a subsea production system and a floating LNG (FLNG) facility. The plan now is to develop the field based on an onshore LNG development concept.

Inpex in partnership with Royal Dutch Shell is currently conducting preliminary front-end engineering design (Pre-FEED) studies for the Abadi field development based on an onshore concept. The LNG project will produce 9.5 MM tons of LNG annually.

When developed, the Abadi field may become the biggest deepwater gas project in Indonesia. It is expected to produce more than 1 billion SCF of gas per day and 20,000 barrels of condensate per day for 24 years.

2. Gula Field

The Gula field is an offshore gas field discovered by Unocal in its Ganal production sharing contract area located in the Kalimantan strait in 2000. With an estimated ultimate recovery (EUR) of 545 MMBOE, it is a giant gas field.

The Gula field, along with the Gendalo discovery and the Gada discovery, is one of the many discoveries made by Unocal in the deep-water area between Kalimantan and Sulawesi. These discoveries confirm that the Central Delta play contains world-class gas resources.

The Gula field is currently an undeveloped discovered resource.

3. Ubadari Field

Ubadari is a giant offshore gas field discovered in 1997. The Ubadari field has an EUR of 500 MMBOE and it is located at Bintuni Bay in West Irian province.

The Ubadari field will supply its gas to the Tangguh LNG plant when the Tangguh LNG Train-3 project is completed in 2020. The Tangguh expansion aims at meeting the ever-increasing demand for energy in Indonesia and accelerating the development of West Irian.

PLN, Indonesia’s electricity company, has signed a sales and purchase agreement to buy up to 1.5 million tons of LNG produced by Tangguh LNG plant annually.

Tangguh LNG plant is scheduled to process the gas produced from the six gas fields located at Bintuni Bay: Vorwata, Wiriagar Deep, Ofaweri, Roabiba, Ubadari, and Wos.

4. Vorwata Field

Vorwata is an offshore giant gas field located in Bintuni Bay in West Irian Province. The Vorwata field, with an EUR of 1833 MMBOE, was discovered by ARCO in the Berau block in 1997. BP became the operator of the Vorwata field after it acquired ARCO.

Gas production from the Vorwata field started in 2009. The field is capable of producing more than 1 BCF of gas per day and the gas is processed into LNG by the Tangguh LNG plant.

5. West Seno Field

The West Seno field is a deepwater oil field discovered by Unocal in 1996. Having an EUR of 553 MMBOE, it is a giant oil field and is currently operated by Chevron.

Lying in water depths of 2,400 to 3,400 feet, the West Seno field is Indonesia’s first deepwater development. It lies in the Makassar Strait PSC off Kalimantan on the continental slope of the northern Mahakam Delta.

The oil is produced using a tension leg platform and a floating production unit, tied back by two export pipelines to onshore infrastructure.

6. Peciko Field

Peciko is a gas field located offshore in the Mahakam Delta in East Kalimantan. The field was discovered by Total with INPEX as its partner in 1991. The Peciko is a giant gas field having an EUR of 1180 MMBOE.

Of all the producing fields in the Mahakam River delta, the Peciko field is unique in that its reservoir trap is both structural and stratigraphic.

The Peciko wells are highly productive having an average well productivity of 80 MMSCF of gas per day. Total daily gas production exceeded 1 BSCF during its peak. A substantial quantity of condensate is being produced along with the gas.

7. Tunu Field

The Tunu field is a supergiant gas field discovered by Total along with Inpex as its partner in 1977. It is located in the shallow waters along the outer limits of the delta offshore Mahakam Block in East Kalimantan. It has an EUR of 4378 MMBOE.

Started in 1978, the Tunu field produces gas and condensate having negligible CO2 or H2S, with the main productive reservoirs lying at depths from 2,200 to 4,900 meters.

Developing the large Tunu field is challenging and producing the gas requires drilling a large number of wells. The field has a large surface area of 20 Km wide and 75 Km long and it is located at the wetland of Mahakam swamp.

8. East Natuna Field

The offshore East Natuna gas field was discovered by AGIP in 1970. It is located 140 miles northeast of the Natuna Islands, Indonesia’s northernmost territory. It is a super-giant gas field with estimated recoverable reserves of 46 trillion cubic feet (TCF) of gas.

There were serious studies done and attempts made by Exxon-Mobil and Pertamina to develop this field.

The field is currently undeveloped due to its very high CO2 content of 71%. To produce the gas will require removing the CO2 from the gas and injecting it back into the reservoir. Production can be commercially viable when the price of oil is above $100 per barrel.

9. Attaka Field

The Attaka field is a giant oil and gas field discovered by Unocal in partnership with Inpex in 1970.   Chevron became the field operator after it acquired Unocal in 2005. Having an EUR of 1000 MMBOE, the Attaka field is located 12 miles from the shore of East Kalimantan.

The huge Attaka reservoir, formed in the very prolific Kutei basin, has an areal closure of 8000 acres. Due to its large areal extent, originally the oil and gas were produced from more than 100 wells located in 6 remote wellhead platforms.

Ten years later, five subsea wells were completed in 1981-1984 to produce the untapped oil accumulation in areas out of reach of the existing remote platforms. These are the first subsea completions in Indonesia.

Attaka field daily oil production was 110,000 BOPD at its peak and gas production was 150 MMSCFPD. Now the Attaka field is quite depleted.

10. Ardjuna Field

The Ardjuna Field is a giant oil field having an EUR of 698 MMBOE. This is the first offshore giant field discovered since the birth of the Indonesian PSC system in 1966.

The Ardjuna field was discovered by ARCO in the Offshore North West Java (ONWJ) production sharing contract area in 1969. Subsequently, it was operated by BP when it acquired ARCO in 2000. Now the field is operated by Pertamina Hulu Energy ONWJ Ltd.

Interesting facts about the Ardjuna field include the drilling of the first horizontal well in Indonesia in 1985 and supplying gas to PLN’s power plant in Muara Karang in Jakarta in 1993.

Pertamina’s refinery in Cilacap began using crude oil from the Ardjuna field in 1986.
