Abstract:
Mari gas field is one of the largest gas fields of Pakistan, located in Central Indus basin.
The Mari Gas Field comprises of two major reservoir rock units, namely Habib Rahi
Limestone and Goru Sandstone. Along with them, other reservoir rock units such as Sui
Main Limsestone and Pirkoh Limestone also exists which are producing Natural Gas.
This study includes a Formation evaluation of two of the Mari Wells, namely Mari Deep
6 and Mari Deep 9.In this study , we calculated different petro physical parameters
including Shale Volume, Density porosity, Neutron Porosity, Average Porosity, Effective
Porosity, Formation temperature, Resistivity Of water, Saturation of water, Saturation of
Hydrocarbon, Permeability, Gross Sand ,Net Sand and Net pay by using different logs
such as CNL log, Gamma ray log, Neutron log, Density log, LLD, LLS.
