Abstract:
This research work aims to understand the Structural and Petrophysical aspects of
JoyaMair area by using Seismic and Well Log Data. For this purpose, four Seismic Lines
and Well Log Data of JoyaMair-04 was provided by LMKR by the consent of DGPC.
Interpretation of the Seismic Data included generation of a Basemap, selection of a
Control Line, generating TD chart and finally picking horizons and faults and extending
the interpretation by Jump Correlation Technique. TWT contour maps were prepared for
Eocene Formations to understand the structural framework of the subsurface geology. The
interpretation of seismic lines along with contour maps shows the presence of a triangular
zone bounded by a fore and back (F1 and F2) thrusts along with basement decollement
(SRT). The overall trapping mechanism is structural.
Petrophysical analysis revealed presence of two reservoir zones i.e. Chorgali
Formation and Sakesar Limestone with average porosity 1.69% and 2.21%, sonic porosity
1.87% and 1.76%, effective porosity 0.14% and 1.57%, saturation of water 96% and 88.8%
and saturation of hydrocarbons 3.9% and 11.1% respectively.
