Abstract

Cambay basin has been proven to be a prolific hydrocarbon bearing area in western part of India. The basin is producing hydrocarbons from mostly strati-structural traps located in in different tectonic segments which are bounded by major faults. The study area is located in Cambay-Tarapur tectonic block where Miocene basal sand and Eocene pay are the prime reservoir units. Due to the presence of coastal marshland in the inter-channel lows, coal is present within the Middle Eocene reservoirs throughout the area. The presence of coal units masks the amplitude response of siltstones and hence it is important to quantify coal and siltstone to characterize the reservoir. Using available seismic (5-60Hz), the coal and siltstone layers cannot be identified due to resolution. The goal of the present study is the quantification of coal and siltstone units in the undrilled area.
