Abstract:
The main purpose of the study was to characterize the Upper Sands of Lower
Goru Formation, Badin Area and Lower Indus Basin, Pakistan. This was achieved by
using complete suite of wire line logs and available well data. This complete set of
data was issued by LandMark Resources, Pakistan in the digital form, with the prior
permission of Directorate General of Petroleum Concessions, Pakistan. To complete
the above mentioned task, the LAS files and the well tops were loaded into the
Geographix software and then correlated to mark the horizon of interest i.e. reservoir
zone. Then isopach maps of Upper Goru and Lower Goru formations were prepared.
After that the Upper Sand of Lower Goru Formation was manually correlated. The
reservoir zones were evaluated for the hydrocarbon potential in detail using the
software, set of equations and different formation evaluation charts made by
Schlumberger. The methodology adopted to accomplish this task include; the
measurements for the shale volume by using gamma ray log, porosities of the
reservoir zone by density, sonic and neutron log, resistivity of water by using
spontaneous potential log, saturation of water in the zone of reservoir and the net pay
of the reservoir zones. The results for the dissertation were then displayed in the form
of excel sheets and graphics for the better approach towards the task.
