摘要: Publisher Summary This chapter explores the geology of abnormal pore pressures in several geographical locations world. The Jhatla area Punjab—in northern Pakistan east Indus river and south foothills Himalayas—shows that it contains a thick, dominantly regressive Tertiary sequence with non-marine Oligocene to Upper Pliocene sandstones silts lying on marine paralic Eocene limestones marls Nummulitic series. prevailing opinion India Burma for overpressures is these are caused by weight superincumbent strata. Abnormal pressure serious problem because causes blow-outs boreholes being drilled petroleum. There much learn about pressures; its proper understanding important exploration development those areas have certain play significant role migration crude oil gas formation traps.
