Abstract: Purpose of the study is the geoscientific work in the Soan Block using seismic and well log data. The seismic lines cover the Bhangali oil field and Pindori oil field. Both oil fields are productive and Pindori oil field has many wells running for the oil extract ion. Six seis mic lines are used for the seismic interpretation. There are t wo major rocks important for the exp loration and production which are Eocene rocks known to be Chorgali Formation and Sakesar Format ion. Thrust tectonics made this area important for the hydrocarbon exp loration. The two important structural traps here are the back thrust on which there are many Pindori wells and the other is fore thrust on which Bhangali wells are present. Also on this fore thrust, there are some other oil and gas fields which have productive wells, so these two thrust faults are of importance. The fore thrust is correlated with the seismological data which proved its oblique slip nature. Due to thrusting and oblique slip, there is huge fracturing which made the Eocene good reservoir. Three wells are used for the well log interpretation. The logs are used for the conformation of the seismic interpretation and then for the calculation of facies of the reservoir rock. Later the facies are confirmed fro m the well reports. The calculated facies are used for the 3D facies modeling which shows the actual sub surface 3D v iew of the reservoir rock.
