Abstract

The objective of this study is to analyze whether fluid and lithology discrimination is possible using Extended Elastic Impedance (EEI) logs within a complex low porosity, low permeability Class I sands. The presence of compressible fluid (gas) in the pore space of rock is known to have considerable influence on elastic parameters like P-impedance and Simpedance but is not often observed in Class I reservoirs. In the East Coast of India wells have also targeted the Class I reservoirs sands. The Well ?A
