Key message- Studies beyond MWP MWP Vs Actual Reliance Industries Limited Activities Performed MWP Actual Performed Remote Sensing / Fracture, Joint and Cleat Mapping Block Area Completed Core Hole Drilling/ Wireline logging 16 64 Gas Desorption/Residual / Bulk density Study 160 1374 IFT Test /skin 213 Pilot Production Well 2 10 Adsorption isotherms  16 137 Coal Petrographic - Proximate/Ultimate/Maceral/Cleat/ Vro /SEM analysis 160-1268 Mechanical property analysis   184 Gas composition analysis 43 Water Composition/ isotopic study 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

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”.

Key Properties & Parameters- Input For Reservoir Modelling Reliance Industries Limited Coal Properties- Reservoir Property- Coal Rank- HV A to MV A Bituminous Reservoir temperature & Pressure Bottom hole pressure Seam depth (350-1200m) Drainage area-Well spacing Thickness( 10-32 m) Skin factor Gas Content Matrix shrinkage Desorption pressure Absolute Permeability-Cleat Porosity Saturation- Langmuir Volume and Pressure Gas Saturation Sorption time Water production limit Pore volume compressibility

Development Approach Reliance Industries Limited CBM exploration is amalgamation of coal mining and oil industries techniques. Technology selection : Technology for drilling and testing. Reservoir characterization, production forecast and field development approach. Some of the technologies were used first time in India. Infrastructure development : Infrastructure development Vendor development. 5 & 9 spot Test wells and Appraisal wells. Evaluation of different technologies. Halliburton, Jacobs and Saipam were consultants in field development Air Drilling, Deeper HQ coring, Injection fall-off Testing, Inseam Drilling, Cavity Completions, Used Ball & Baffle for zonal Isolation.
