Abstract
The studied well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform marks the eastern part of Central Indus Basin, tectonically it is stable part of Indus Basin and was least affected during Tertiary Himalayan orogeny. The well under study is the only exploration well of the area. This study attempts to decipher reservoir potential for hydrocarbon exploration. It aims to delineate a subsurface hydrocarbon bearing zone and estimation of reservoir properties. A complete suite of wireline logs containing Caliper log (CALI), Gamma ray log (GR), Spontaneous Potential log (SP), Neutron log (ØN), Density log (ØD) and Resistivity logs (MSFL, LLS, LLD) with all drilling parameters and well tops were utilized. The methodology adopted to accomplish this task includes; the calculation of volume of shale (Vsh) by using Gamma Ray Log, effective porosity (ØE) by using Density and Neutron Logs. Resistivity of water (Rw) was calculated by SP method. Saturation of water (Sw) and Saturation of hydrocarbons (Sh) is calculated with the help of Archie’s equation. According to log signatures Lumshiwal Formation of early Cretaceous age encountered in well at the depth of 5433ft to 5797ft marked as possible reservoir, this zone is evaluated for its reservoir potential in detail using set of equations. The average values calculated for different parameters are; Vsh is 30%, ØE is 17%, Sw is 46% and Sh is calculated as 54%. Analysis shows that the Sh is low so it is inferred that Lumshiwal Formation have low potential and economically not feasible for hydrocarbons production
