Reservoir Characterisation of Lower Cretaceous Clastic Succession of Nizampur Basin, Eastern Tethys, Pakistan
Keywords:
Kala Chitta Ranges; Lower Cretaceous sequence; Petrography; Reservoir characterisationAbstract
The present integrated study is held to carry out the control of depositional and diagenetic processes on the reservoir potential of the Lower Cretaceous sequence within Nizampur Basin (Kahi Village section) and Kalachitta Range (Tora Stana section). This study was carried out in order to analyse the effect of the depositional and diagenetic processes on the reservoir potential of the studied strata. The Lower Cretaceous sequence at the western part of the Kala Chitta Ranges is mainly composed of sandy limestone and sandstone facies. Petrographic details show that the sandstone is mineralogically mature in both sections while it is texturally immature to sub-mature at Tora Stana section and sub-mature to mature at Kahi Village section. The microscopic details indicate that the sandstone at Tora Stana section is deposited in inner to middle shelf setting, while it indicates moderate to high energy condition of beach to inner shelf setting in Kahi Village section. The results of Image J software show that the porosity of this clastic succession ranges from 2-5% at Kahi Village Section, while in the fractured and dolomitic samples the porosity exceeds up to 13.5%. The dolomites are in the form of small patches which will not add pronounced contribution to the overall porosity. At Tora Stana section the average porosity ranges from 4-7%
