Abstract:
The study includes the comprehensive research conducted to assess the
conventional and unconventional hydrocarbon potential of the Kadanwari Wells 01, 03,
and 10, which were drilled in the Middle Indus basin in Sindh Province's Tajjal region.
In all three wells, Lower Goru was designated as the target lithology. The goal of this
study was to evaluate the reservoir properties of sand and shale intervals in the Lower
Goru Formation using conventional and unconventional methods. The mineralogical
composition of the Lower Goru Formation was determined utilizing three mineral
methods to achieve this goal. Total Organic Content (TOC), Brittleness Index, and
Shale Porosity were used to calculate the production potential of unconventional wells.
The study of the formation's mineralogical composition required Shale cross-plots,
Porosity cross-plots, and Reservoir cross-plots, while the production capacity was
determined by estimating Volume of Shale, Resistivity of Water, Saturation of Water,
Saturation of Hydrocarbons, and different porosities. The lateral variations of reservoir
characteristics were also assessed using stratigraphic correlation. At various intervals,
subsurface geophysical evaluation indicated both conventional and unconventional
shale reservoir potential.
