Using Dipole Sonic Logs and Rock-Physics Principles for Enhanced Detection of Thinly Laminated Gas Sands

G002 USING DIPOLE SONIC LOGS AND ROCK- PHYSICS PRINCIPLES FOR ENHANCED DETECTION OF THINLY LAMINATED GAS SANDS R. BASTIA (RELIANCE INDUSTRIES) AND Abstract 1 Deep-water exploration in the Krishna-Godavari offshore basin India has resulted in the largest gasfield discovery in the world in recent years. The Krishna-Godavari basin is located in the east coast of India bordering the state of Andhra Pradesh. The basin consists of a sedimentary area of approximately 100 000 sq. km in both land and sea. Eight exploration wells intersected numerous gasbearing formations consisting of highly porous and permeable unconsolidated blocky sands and thinly laminated shale-silt-sand
