Malaysia is the second largest oil and gas producer in Southeast Asia, with proven oil reserves of 3.7 billion barrels and proven natural gas reserves of 38.5 Tcf as of 2013. Its western coast runs alongside the Strait of Malacca, a significant energy corridor linking the Indian and Pacific Oceans, while the eastern part of the nation contains the states of Sabah and Sarawak. Nearly all Malaysiaâ€™s oil is produced from offshore fields. These are located on a continental shelf comprising the Malay basin in the west and the Sarawak and Sabah basins in the east. Major companies active in Malaysiaâ€™s oil and gas industry are national oil company Petronas, ExxonMobil and Shell.
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.
