Reliance completed the exploration program by drilling 64 wells to the depth below the targeted Barakar seams. For each Corehole, gas content data were gathered, geophysical logging was conducted, and in-situ permeability testing ( first time in India) was also performed in most of the wells. Coring operations were done in a very efficient and timely manner, utilizing a wireline retrieval coring system which minimize the trip time to reduced the Lost Gas.
Key message- Studies beyond MWP

5. World Class Find
Reliance
Industries Limited
Geological assessment of the area from information of data package
Surface Studies:
Lineament Studies from satellite images by ARI-USA.
Structural delineation (fractures, joints and faults).
Cleat, joint and fracture mapping.
Subsurface Studies:
Exploratory core holes located and preliminary CBM fairways identified
Geological modelling and risk assessment
Resource estimation and validation by RIL and external agencies
Fairway delineation
CBM experts of ARI and Higgs Technologies after working with Sohagpur field termed it as a ‘’World Class Find”.
