THE MAKING OF A WORLD CLASS CBM PROJECT Reliance Industries Limited

HSE at Reliance Industries Limited

Block Location Reliance Industries Limited Area overview • Blocks located in tribal notified districts of Shahdol & Annupur • ~ 300 sq. km out of total block area of 995 sq. km is occupied by forest • Total population of Shahdol is 1, 064, 989 with ~79% people living in rural area • District has coal mining & few industries Current portfolio includes only first CBM round blocks 3

MWP Vs Actual Activities Performed Reliance Industries Limited MWP Actual Performed Block Area Completed 16 64 160 1374 16 213 • Remote Sensing / Fracture, Joint and Cleat Mapping • Core Hole Drilling/ Wireline logging • Gas Desorption/Residual / Bulk density Study • IFT Test /skin • 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 Completed 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 • Coal Properties • Coal Rank- HV A to MV A Bituminous • Seam depth (350 -1200 m) • Thickness( 10 -32 m) • 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 Reliance Industries Limited • Reservoir Property • • Reservoir temperature & Pressure Bottom hole pressure Drainage area-Well spacing Skin factor

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. • Infrastructure development : • 5 & 9 spot Test wells and Appraisal wells. • Evaluation of different technologies.

CBM O&M Facilities • Well site facilities • Gas pipeline network • Water network • GGS facilities • Power network • Instrumentation & SCADA network • Fire & gas detection system Reliance Industries Limited
