The buoyancy force produced by the difference in density between water and hydrocarbons drives migration. Migration will cease, and a hydrocarbon reservoir ... Ayoluengo structure is a faulted anticline. Oil and gas are reservoired within a series of thin lenticular sandstone packages of Late Jurassic-Early Cretaceous age. More than 50 separated reservoir beds have been identified. Reservoir properties are fair to good, with porosities commonly ranging 12 to 18%.A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements …Abstract. K field is a faulted anticline structure lying in a turbidite environmental setting, which consists of two main sand bodies of 50-100ft gross thickness. Two main challenges during development stages were, 1). The narrow thickness of the fault block requiring accurate landing, well placement and characterization. 2).
