The U.S. Geological Survey estimated mean volumes of 1.6 billion barrels of undiscovered conventional oil and 17 trillion cubic feet of undiscovered conventional natural gas in three geologic provinces of Thailand using a geology-based methodology. Most of the undiscovered conventional oil and gas resource is estimated to be in the area known as offshore Thai Basin province.
Conventional accumulations represent oil and gas accumulations that are buoyant upon a water column, whereas unconventional accumulations generally do not rely on buoyancy.
