This is why Brunei is rich of oil, from geological perspective

Brunei, located on the island of Borneo in Southeast Asia, is known for its vast reserves of oil and natural gas. The oil and gas industry is the backbone of Brunei's economy, accounting for more than 90% of its GDP. But why is Brunei so rich with oil? Let's explore the geological factors that contributed to the formation of oil deposits in Brunei.

Oil is formed from the remains of tiny plants and animals that lived in ancient oceans millions of years ago. When these organisms died, their bodies sank to the bottom of the ocean and were buried under layers of sediment. Over time, the pressure and heat from the overlying sediment turned the organic matter into oil.

One of the key factors that led to the formation of oil deposits in Brunei is the presence of source rocks. Source rocks are rocks that contain organic matter that can be transformed into oil and gas. In Brunei, the main source rocks are shales and mudstones that were deposited in a shallow marine environment during the Eocene epoch, which lasted from about 56 to 34 million years ago. These rocks are rich in organic matter, and under the right conditions, they can generate large amounts of oil and gas.

Another important factor is the presence of reservoir rocks. Reservoir rocks are rocks that can hold oil and gas in the tiny spaces between the grains. In Brunei, the main reservoir rocks are sandstones that were deposited during the same time period as the source rocks. These sandstones are porous and permeable, which means that they can hold large amounts of oil and gas and allow them to flow through the rock.

Finally, the presence of traps is also crucial for the formation of oil deposits. Traps are geological structures that prevent oil and gas from escaping to the surface. In Brunei, the main traps are formed by folds and faults in the rock layers. These traps can create a reservoir of oil and gas that can be tapped by drilling wells.

In summary, the formation of oil deposits in Brunei is the result of a combination of geological factors, including the presence of source rocks, reservoir rocks, and traps. These factors came together during the Eocene epoch to create one of the world's largest reserves of oil and natural gas.

I began my career in the banking industry in 1997, and stayed approx 6 years in it. This industry boost his knowledge about the economic condition in Indonesia, both macro and micro, and how to More understand it. My banking career continued in Yogyakarta when I joined in a program funded by the Asian Development Bank (ADB),as the coordinator for a program aimed to help improve the quality of learning and teaching process in private universities in Yogyakarta. When the earthquake stroke Yogyakarta, I chose to join an international NGO working in the area of ?disaster response and management, which allows me to help rebuild the city, as well as other disaster-stricken area in Indonesia. I went on to become the coordinator for emergency response in the Asia Pacific region. Then I was assigned for 1 year in Cambodia, as a country coordinator mostly to deliver developmental programs (water and sanitation, education, livelihood). In 2009, he continued his career as a protocol and HR officer at the U.S. Consulate General in Surabaya, and two years later I joined the Political and Economic Section until now, where i have to deal with extensive range of people and government officials, as well as private and government institution troughout eastern Indonesia. I am the founder and Editor-in-Chief in Good News From Indonesia (GNFI), a growing and influential social media movement, and was selected as one of The Most Influential Netizen 2011 by The Marketeers magazine. I also wrote a book on "Fundamentals of Disaster Management in 2007"?, "Good News From Indonesia : Beragam Prestasi Anak Bangsa di dunia"? which was luanched in August 2013, and "Indonesia Bersyukur"? which is launched in Sept 2013. In 2014, 3 books were released in which i was one of the writer; "Indonesia Pelangi Dunia"?, "Indonesia The Untold Stories"? and "Growing! Meretas Jalan Kejayaan" I give lectures to students in lectures nationwide, sharing on full range of issues, from economy, to diplomacy Less
