Ilam Formation is deposited at the late Cretaceous (Santonian) in a neritic/pelagic environment.
Following the Ilam deposition, a general deepening has occurred and the Gurpi formation (shaly layer) was deposited.
Ilam has thickness variation between 75-110m and structure has created as a result of upward movement of deep seated salt.
Ilam reservoir in this field is regarded as a secondary hydrocarbon potential, and since now, no oil has been produced from this horizon.
petrophysical and Seismic interpretation has been done for the Ilam reservoir, the geological models (structural and property models) are generated, with both deterministic and stochastic approaches.
The seismic attributes as secondary variables, improved the kriging and Sequential Gaussian Simulation (SGS) algorithm results for modeling of Ilam.
This study reveals that Water Saturation is generally high, indicating that Ilam reservoir has low hydrocarbon potential, within the five reservoir potential zones, the zone 5 indicated a good original oil in place potential, especially in the western and central parts of the field.
