Abstract:
Chanda field is located in the Shakardara, District Kohat in Khyber
Pakhtunkhwa province of Pakistan. The study area lies in the compressional tectonic
regime exhibiting thrust and folding structure. Datta and Lockhart formations are
acting as a potential reservoir. In the present study hydrocarbon potential of Chanda
Field has been interpreted by evaluating the well logs of Chanda Deep-01 and Chanda
02 in terms of reservoir characterization. Petrophysical interpretation carried on two
reservoir rocks of wells; Chanda Deep-01 and Chanda -02, which illustrates that the
Lockhart and Datta formations have a property of being a good reservoir. Source rock
evaluation is only done for Datta Formation of Chanda Deep-01 well, because Datta
Formation contains some of the shaly portion. For the evaluation of source rock D R
log technique of Passey has been adopted. Cross plots of resistivity deep log (LLD)
vs Density (RHOB), LLD vs Sonic (DT) and LLD vs Neutron porosity (NPHI) log
has been made. By the interpretation of these logs we find that Datta shale is matured
and having good TOC value 2.0 wt %.
