PRELIMINARY STUDY ON THE OIL AND GAS EXPLORATIONTARGETS IN OFFSHORE PAKISTAN

In order to find out the future direction for oil and gas exploration in the offshore areas of Pakistan, a large amount of literatures was collected and analyzed, and the newly collected columnar samples were tested and analyzed. It was found that source rocks are available in offshore Pakistan and reservoirs are mainly composed of Miocene channel sandstones and Eocene reef limestone. In the northern part of Pakistan Seas, however, the sediments were mainly sourced from the fine-grained clastic rocks of the Makran accretionary wedge, and the Miocene channel-levee complex is limited, and thus the oil and gas exploration prospects are quite poor. However, in the Indus fans off eastern Pakistani, the channel-levee complex is widely distributed as high quality reservoirs. Therefore, it is suggested that the Indus fan in the eastern Pakistan Sea be selected as the target area for future oil and gas exploration taking the Miocene channel sandstone on the continental shelf and the Eocene reef limestone in the deep water as main exploration horizons.
