Source rock evaluation and reservoir characterization of Chanda oil and gas field, upper Indus basin, Pakistan (T-1387) (MFN 4281)

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 %.
