Green Hydrogen



Hydrogen is a clean and efficient energy source. It is being used to power hydrogen cars and buses in several environmentally conscious countries. Hydrogen cars are very clean. They have zero emission and they emit only water vapor. As an example, the city of Aberdeen in Scotland is using hydrogen buses to reduce emission and boost air quality at the city centre.

As energy carrier, hydrogen stores and delivers energy efficiently. Hydrogen cars uses fuel cells to convert the chemical energy stored in the hydrogen into electricity, whereas electric cars use the electricity stored in the car batteries to power the electric motors.

Although many compounds, especially hydrocarbons and water, contain lots of hydrogen atoms, free hydrogen is very scarce in nature. Our air has only .00005% of free hydrogen. Currently most hydrogen is produced from fossil fuel by stripping off the hydrogen atoms from the hydrocarbons. Therefore, hydrogen cars are not considered as totally green.

To make hydrogen cars truly green, people are considering using green hydrogen. Green hydrogen is hydrogen which is produced using electricity generated from renewable energy resources such as wind, solar and geothermal.

New Zealand is currently experimenting powering hydrogen cars using hydrogen produced using geothermal resources.

Toyota expects 30% of vehicles to be hydrogen powered by 2050.

Why People Need Oil Price Forecasts


People, companies and even countries want to know future price of oil because oil price influences what they do.
Individuals use the information for his or her investing such as whether to buy oil related shares.
Banks need it for giving out oil related loans.
Transportation companies use it to manage its fuel expenditures such as whether to buy or sell oil futures.
Oil companies need it to manage their operating and capital expenditures such as whether to drill or not to drill.
Oil exporting countries use it to determine its GDP.
Oil importing countries need it for planning its annual budget.
Perhaps the greatest role of oil price forecast is in IPOs and M&A.

US Shale Oil Hitting New Highs



US shale oil output is projected to hit above 6.5 million barrels of oil per day in February 2018 and is leading a recovery in US oil production.

Oil output from shale is projected to increase by 111,000 BOPD in February according to US Energy Information Administration. With this increase, the total shale oil output is expected to reach 6.55 million BOPD in February 2018.

US total oil production is also reaching new highs. EIA forecast that total US oil output will hit annual average of 10.3 million BOPD in 2018 and 10.8 million BOPD in 2019.

At 10.8 million barrels of daily oil production, the US would be one of the world’s top oil producers along with Saudi Arabia and Russia.

What Profession Is Best For You or Your Children?


Robert Kiyosaki said A students become professionals such as engineers, accountants, lawyers, scientists, consultants, doctors, IT specialists etc.

He then said B students work for government and C students become entrepreneurs.

Let’s analyse the characteristics of each of these three categories of profession.

In category A, as a professional, you have very good income and decent job security. This is a low- risk yet high income profession.

In category B, as a government worker, you have adequate income but excellent job security. This is also a low- risk profession providing sufficient income.

In category C, as a business entrepreneur, you can become very rich but you have low job security. This is a high-risk profession. As a business person, you may suffer losses or have negative income. This is a high reward and high-risk profession. The positive correlations of high rewards with high risks is a proven economic theory.

So then, what profession is best for you?

Since I have been a professional and an entrepreneur, I like to share with you my thoughts and suggestions. There is no such a thing as the best profession in the world; but for everyone, there is one profession which is best just for him or her. To determine the best profession for you, you should consider these factors:

  1. What are your dreams?
  2. What are your objectives in life?
  3. What profession will fulfil your dreams and life objectives?
  4. What are you good at?
  5. What do other people say you are good at?
  6. How well do you handle stress?
  7. How important is job stability to you?
  8. How healthy are you?
  9. Are you good at problem solving?
  10. Are you a multi-tasking person?
  11. Are you good in handling rejections?
  12. Are you a generalist or a specialist?
  13. Are you a people person or a task person?
  14. Are you a risk-taker of risk avoider?
  15. Are you good in managing money?
  16. Are you the sole breadwinner, the only person who supports the family financially?
  17. Can you afford to fail or lose money?

After you have considered these factors and you still have not found the answer, you should follow your heart. Your body and soul will tell you what is best for you.

You shouldn’t be afraid to fail if you can afford to fail. You will have challenges and failures in your journey to reach your dream; but with each failure you face, you are closer to where you want to be.

Finally, since nowadays most people will change job 3-5 times in their working life you shouldn’t worry too much which profession you choose. Every profession you are in is a bridge or a stepping stone to a better profession. Very often as you go forward in your career, the path leading to your dream will appear in front of you.

10 Interesting Facts About The Super-Giant Oil Field of Attaka

Attaka platform - 22051165_10203849223866343_116962473911316990_o

This is the Attaka field, a super-giant offshore oil field located 12 miles from the shore of East Kalimantan in Indonesia. It was discovered by Unocal in August 1970. Unocal, and later on Chevron, was the operator of the Attaka unit on a 50-50 interest basis with Inpex. Attaka field is considered a super-giant oil field having 1023 MMBOE of recoverable reserves.

Here are the interesting facts about the Attaka unit:

  1. Two years after its discovery, Attaka field started producing oil in November 1972, making it as the first offshore field in Indonesia.
  2. It has 10 platforms, 6 of which are remote well head platforms producing oil and gas from 109 wells.
  3. Five subsea wells were completed in 1981-1984 to produce the oil accumulation in areas out of reach of the existing remote platforms. These are the first subsea completions in Indonesia and in Asia.
  4. Following the first discovery well, the Attaka Well 1A, seven appraisal wells were drilled to assess to size and potential of the hydrocarbon accumulation.
  5. The huge Attaka reservoir, formed in the very prolific Kutei basin, is a faulted anticline. It has an areal closure of 8000 acres. Attaka field is one of five super-giant fields discovered in the Kutei basin.
  6. Its oil reserves are attributed to oil found in 22 separate sands at depth between 2800 feet and 7600 feet.
  7. Attaka sands have very high permeability. It is as high as 5 Darcy in some wells.
  8. Attaka field daily oil production was 110,000 BOPD at its peak and gas production was 150 MMSCFPD.
  9. A significant milestone was reached when cumulative oil production of 600 million barrels was recorded at 6:42 PM in March 7, 2001. Cumulative gas production in that same year was 1.3 trillion SCF.
  10. Attaka field has more than 50 sands with variable oil reserves. Reservoir sand thickness ranges from 5 to 100 feet. To produce them economically, multiple zone completion method using dual tubing strings and multiple packers was selected. This method allows the engineers the flexibility to select from which of the 2 to 4 perforated zones in each well they would like to produce from.
