Abstract:
Choti 01 is located in Punjab province, in the district of Dera Ghazi Khan, and is
part of the Sulaiman depression of the Middle Indus Basin, which has monoclinal features.
The following study combines seismic and well log data methodology to evaluate
hydrocarbon potential. Making the TD chart with Choti-01 well tops identified the
objective horizons. The available stacking velocities on the seismic sections are used to
convert time to depth. The Monoclinal structure has become shallower in the east and
deeper in the west. The reservoir rocks are the Late Eocene Sui Main Limestone and the
Early Paleocene Dunghan Formation. The Eocene shale of Ghazij acts as a regional seal.
The Sui Main Limestone, which is Eocene in age, was the research area's main formation.
The presence of a Monocline from east to west has been confirmed by two-way time and
depth contour maps generated as a results of interpretation. For formation evaluation and
possible hydrocarbon bearing zones, a petrophysical investigation is performed on the well
Choti-01. On logs, just one zone, the Sui Main Limestone of 50 m thickness, has been
recognised. Through the results of petrophysical analysis, is very promising for
hydrocarbon potential., an average hydrocarbon saturation of 31.6 percent, and water
saturation of 68.3 percent. This well is abandoned due to tight effective porosities and high
water saturation in the zones.
