Abstract

In the Kalol Formation of Nawagam Field in Cambay Basin, significant hydrocarbon bearing wells have been drilled but even at present, its true potential remains untapped. Nawagam field lying to the south of Ahmedabad- Mehsana Block of Cambay Basin has mainly produced from KIX and K-X pays. However, K-III+IV Pays lying about 30-40m above K-IX pay remains mostly unexplored. Merely seven wells have been tested in this pay which has evoked the interest to relook and to bring out an understanding of the extent of this reservoir for the future development of this pay. With changing times, it becomes pertinent to relook into such pays which were difficult to exploit and remained sub-economical in the past. The real challenge is faced due to varied log responses, low resistivity and the reservoir thickness which could not be resolved in seismic. The process involved amalgamating seismic data along with petrophysical interpretation and well data analysis. Static Geo-cellular model for this pay has been prepared integrating well data of 340 wells. This integrated workflow has been carried out for the first time focusing on this pay and has successfully brought out the prospective areas which will play as a vital input for future exploration and exploitation for tapping the true potential of this reservoir
