2D-INTEGRATED SEISMIC INTERPRETATION, ATTRIBUTE ANALYSIS, PETROPHYSICAL ANALYSIS & ROCK PHYSICS BASED FACIES ANALYSIS OF MISSA KESWAL, INDUS BASIN, PAKISTAN

Abstract

Missa Keswal area is part of Potwar sub-basin or Upper Indus hasin which is known for hydrocarbons and structural traps. TIle area is important for its hydrocarbon (oil and gas) Slntctural traps. Missa Keswal oilfield is located at the distance 01'60 kIn's in the Smuh East oflslamabad.ll1c field was diScovered in June 1991 und came on regular production from December 1992, The present study has been done on seismic and well log datu provided by the Directorate General of Petroleum Concession (DOpe). For the interpretation of seismic data, the I!-IS Kingdom software is used. The horizons were identifil!d using formalion lOpS from wells and their depths were confirmed through correlation with synthetjc seismogram, four reflectors named as Murrec, Chorgali, Sakesar, Lockhart and basement have been marked depending on prominent wiggles & information of Missa Keswal-03. Faults were also marked Lo examine the subsurface structure. Compressional regime in the area cause faulting and salt of Pre-Cambrian age disturbed the basement creatjng popup structures. 111esc Pop-up (anticlinal) structures can be seen in the area, they act as a trap and considered best for hydrocarbon accumulation. Time and depth conlour maps of all Fonnalions are also prepared 10 analyze the variations on the basis of time and depth. Seismic attribute analysis is also pcrfonned for the confirmation of 2D Seismic interpretation and it also highlights lhe zone of interest. Petrophysical analysis is done which shows hydrocllrbon and water saturation in Missn Kcswal-03. Rock Physics cross-sections huve gencmted to further confirm the interpretation.
