Abstract

The deeper exploratory plays are presently considered as one of the thrust areas of exploration in Bombay Offshore Basin. These include Paleocene-Early Eocene clastic play, Paleocene-Early Eocene carbonate play, Fractured basalt play and possible Basin Centered Gas Accumulations (BCGA) in the basinal lows. Hydrocarbon accumulation in the deeper sequence is mainly strati-structural, controlled both by the development of reservoir facies, its continuity and the structural configuration. Unconventional plays like fractured basement along the Eastern Homocline and possible Basin Centered Gas accumulations (BCGA) are also envisaged in the Daman low and Central graben. The rising flanks of Daman low, Navsari low, Diu depression, Central graben and South Bombay depression would be encouraging for the deeper plays. The major challenges in exploration of deeper plays include geological modelling of the deeper plays, seismic imaging and mapping of the thin and discontinuous sands, combating high pore pressure and establishing the unconventional plays like Basin Centered Gas Accumulations (BCGA). Intensive adoption of new technologies for imaging deeper plays, sound well completion technology for handling HPHT related problems and modern electro-logging suites including LWD has to be hastened for exploration and exploitation of deeper plays
