2D-SEISMIC REFLECTION DATA INTERPRETATION OF LINES GO-017-SNJ-03, GO-017-SNJ-08 AND GO-017-SNJ-22 OF SANJHORO AREA PAKISTAN

Abstract

The dissertation work includes seismic data interpretation, seismic attribute analysis, Petrophysical analysis using well logs data; identification of possible resource plays as well as use of rock physics to estimate physical properties of rocks.Seismic and well log interpretation used for study of structural style, physical properties of rocks and identification of possible petroleum system of Sinjhoro area (Lower Indus Basin) Pakistan. The seismic section shows Horst and Graben structure bounded by normal faults Time and depth contour maps were prepared to analyze the overall behavior of the structure. There are small anticlinal structures bounded by two normal faults which is clue towards either horst and graben structures to some extent. Well locations are proposed by constructing time and a depth contour map which shows faulted anticline in study area. Seismic attribute analysis is then applied to confirm both structural and stratigraphic interpretation. Petrophysical analysis of wells Chack66-01 is carried out for Lower Goru in order to depict the probable hydrocarbon producing reservoir. The results suggest that Lower Goru Formation is more producing reservoir rock.Rock physics will be performed on Reservoir zone to find out the rock characterization. Elastic Modulus decreases in the interested zone which shows that it is hydrocarbon saturated. Petrophysical results are confirmed by rock physics. Seismic attributes analysis of seismic section helps in identifying the different lithological boundaries and further confirmed the structural and stratigraphic interpretation and petroleum play of the study area
