Abstract:
The main purpose of the study is to evaluate hydrocarbon potential of a well named
Choti-01, Central Indus Basin, Pakistan. This has been achieved by using complete suite of
wire line logs and available well data. This complete set of data is issued by Land Mark
Resources, Pakistan with the prior permission of Directorate General of Petroleum
Concessions, Pakistan. To complete the above mentioned task all logs were correlated to
mark the zone of interest i.e. reservoir zone. In our case the reservoir is lying in Sui Main
Limestone. After the demarcation of reservoir (Sui Main Limestone), this zone was then
divided into sub zones according to the quick look interpretation.These zones were evaluated
for the hydrocarbon potential in detail using set of equations. The methodology adopted to
accomplish this task includes; the measurements for the Shale volume by using Gamma Ray
Log, Porosities by Sonic Log, Resistivity of water by using Rwa method, Saturation of water
in the zone of reservoir and Hydrocarbon saturation using Archie equation. The results for the
dissertation were then displayed in the form of excel sheets and graphs for the better
approach towards the task. These all displayed results show that the Sui Main Limestone of
Choti-01 well has considerable amount of hydrocarbon.
