Evolution of Geosteering Technology Helped in Successive Development of a Brown Field - Case Study from Mumbai High

Mumbai High, a highly heterogeneous multi-layered carbonate sequence with shale intercalation, played a critical<br>role to quench the energy thirst of a big developing country like India. Mumbai High field is divided into two blocks<br>i.e., Mumbai High North (MHN) and Mumbai High South (MHS) by a major WNW-ESE trending graben containing<br>impermeable shale.
