Geology/Hydrocarbon traps from OIl FIelds in PAkistan


Aoa. Sir, can you please quote the different type of structural and stratigraphic traps from Upper, MIddle and Lower Indus Basin in Pakistan ?
Have we obtained any oil production from SALT DOME type traps in Pakistan ? I have one more question in mind but I want to clear my mind about this first.


In Kohat-Potwar area (Upper Indus) we mainly have structural traps. Fault-bounded pop-up structures are common in the eastern Potwar (like Adhi). Fault-bounded with dip closure on three sides are encountered towards west.

In Middle Indus region the Sulaiman Range offers relatively narrow but long N-S oriented anticlines (Zindapir etc). In Sulaiman Lobe region we generally have broad domes like Sui. Kandhkot, Qadirpur, Mari etc.  Along the eastern flank of Jcobabad-Khairpur high we do find stratigraphic-cum-structural traps. While in Punjab Platform the possibility of up-dip pinchouts towards east exist; horst-graben geometry is also common.

In Lower Indus basin, we have broad domes in Kirthar fold belt, while dominantly horst-graben geometry traps are productive in Badin area; east of Badin area updip pinchouts may provide stratigraphic plays.

I am not aware of oil production from a salt dome type of trap in Pakistan.
