3D Reservoir Modeling to Evaluate Tight Gas Potential of Miano Field, Central Indus Basin, Pakistan (T-1517) (MFN 5012)

Abstract

Miano gas field located in Central Indus Basin, Pakistan, was selected to evaluate Tight Gas potential and to estimate Gas in place using static model with the aid of geophysical dataset comprising of PSTM 2D Seismic lines (01 strike line and 05 Dip lines) and Wireline logs of 03 wells (Miano-02, Miano-07 and Miano-09). B sand Interval deposited as tidal channel sands in a shoreface/ Barrier island complex setting is acting as reservoir in this field. The methodology adopted for this study comprised of Seismic Interpretation, Petrophysical analysis and Modeling. Time and Depth contour maps for C-sand, B-sand and A-sand interval were prepared during Seismic interpretation which were then used as inputs to define the external architecture of the model. Petrophysical analysis was performed to determine reservoir properties (Phie, Water saturation, Permeability & Net/Gross) of B-sand and were subsequently incorporated in 3D model during property modeling phase. 3D static modeling comprised of three main steps namely Structural Framework Modeling, Corner Point Gridding and Property Modeling. Based on the interpretation of available dataset the study concluded that the B-sand is acting as a conventional reservoir throughout the study area.
