Abstract

Compressional and Shear wave velocities (Vp & Vs ) have been measured on dry and brine saturated core plugs of GS-15 and 23 structures of KG Basin under ambient as well as insitu confining pressure conditions. The data generated demonstrate simple linear relationships between Vp and Vs . For dry core plugs, the Vp -Vs curve passes through zero and it indicates a nearly constant Compressional to Shear wave velocity ratio. However, for brine saturated core plugs, the relationship between Vp and Vs is found to be as follows: For GS
