Abstract

Mumbai High, a giant oil field located in western offshore, is considered in the world oil industry as one of the most complex field , especially from geological and geophysical ( G&G ) point of view. In view of this, optimising oil production from this field, has been a challenging task to geoscientists over the years. In recent times the industry has witnessed significant advances in geo-scientific areas such as 3D seismic, Logging While Drilling ( LWD ), reservoir simulation etc. Of late, some of these high end technologies have successfully been attempted for micro level understanding of Mumbai High reservoirs. The results, though encouraging, still fall short of requirement. However, advances made in drilling and completion technologies, to a great extent are helping in achieving higher per well production rates, G&G complexities notwithstanding. This paper addresses, in brief, the results of geo-scientific understanding of this matured multi-layered carbonate reservoir and technological achievements towards optimising oil production from Mumbai High field.
