The basement reservoirs always occur on highs or uplifts within the basin, and have been subjected to long periods of weathering and erosion. Younger sediments (presumably source beds) directly overlie basement, providing opportunity for entrapment of oil in the basement rock. Almost all basement reservoirs occur below a regional unconformity.
