Abstract

There are number of small oil fields located in western onshore undergoing a fast-track development campaign, wherein wells have witnessed NPT due to various drilling challenges such as tight hole, stuck pipe etc. Bad borehole condition has affected the data quality being recorded for formation evaluation and poor cement quality. Most of these drilling problems are reported in shallow shale formations like Tarapur, Post-Kand and Babaguru. Target reservoirs like Kalol and Cambay shale are relatively silty with porosity in range of 6%-10% which requires hydro-fracturing jobs to enhance production. Simulations for Hydrofracturing operations to estimate the fracture height and width are primarily dependent on rock mechanical properties such as anisotropic Young
