Production is expected to begin in May 2014 from a cluster of oil and gas fields in the Mumbai High area offshore western India to be developed by state-owned Oil & Natural Gas Corp.

The B-127 cluster, east of Mumbai High oil field, includes marginal fields B-127, B-157, and B-59. ONGC estimates reserves at 15.35 million tonnes of oil equivalent, with 24.6 million tonnes in place in the Eocene Bassein and Paleocene-Eocene Panna formations.

The company estimates total production of 1.836 million tonnes of oil and 2.093 billion cu m of natural gas over 10 years.

It also will extend development of B-55 field, northeast of Mumbai High and the B-127 cluster, on production since November 1999 and currently yielding about 2.05 million standard cu m/day from nine wells. The exploratory well B-55-5 produced gas from the Oligocene Mukta formation, warranting further development, ONGC said. The operator expects incremental production of 155,000 tonnes of oil and 2.583 billion cu m of natural gas over 13 years.

Also east of B-127, ONGC reported a discovery in the B-127E-1 well, which during drilling to 2,735 m encountered hydrocarbons in “various intervals” of the target Panna formation.

On a test of one of five intervals of interest, at 2,651.5-2,648.5 m, the well flowed 1,076 b/d of oil and 1.9 million cu m/day of gas through a ½-in. choke.
