The Speculative Role of Epeirogenic Movements in Oil Migration and Accumulation in Mesozoic Reservoirs of Sulaiman Fold Belt of Balochistan, Pakistan

Abstract

The role of the epeirogenic movements in oil migration and accumulation in the Sulaiman fold belt has been speculated in the light of the evidence provided by the occurrence of subaerial surfaces of weathering and the oil seeps. The area and the horizons of emergence in the Jurassic and Cretaceous have been examined. The study has led to figure out the structures ofthe Chiltan limestone and the overlying formations before and after the Himalayan orogeny.
The oil migration and accumulation from the Sembar source have been depicted and the influence of the hydrodynamic force on the pools has been pointed out along with the recommendations for future exploration in the area.
