Abundant energy resources are available in East and South East Asia. Major energy producing countries in the region include China, Malaysia and former OPEC member Indonesia, while Myanmar may potentially join the producing group following the end of military rule and the opening of the nation's petroleum sector to more foreign investments. Brunei, China, Indonesia, Malaysia, Thailand and Vietnam have an estimated 31.4 billion barrels of proven oil reserves and 309.5 trillion cubic feet of proven natural gas reserves as of 2013.
Geophysicists play an important role in the oil and gas industry as they help find underground oil and gas deposits by creating a clear picture of what is below the earth’s surface. Using physical methods (seismic, gravitational, magnetic, electric) they measure the physical properties of subsurface earth to detect or infer the presence of oil or gas. The most common way to create a clear picture of the earth's subsurface is through the seismic method whereby shock waves that are set off at the surface resonate through the earth, and the returning echo can be used to tell what is beneath the surface. Geophysicists are usually classified into three categories: acquisition, processing and interpretation. A strong geoscience, physics, or mathematics background is necessary for a career in geophysics.
