NEW DELHI, IndiaONGC plans to invest $66.05 million in developing the North West B-173A field to enhance production from its Western Offshore facilities off India.

The NW-B-173A field is 5 km (3.1 mi) northwest of theB-173A field, in turn around 25 km (15.5 mi) north of the Neelam field, in an average water depth of 55 m (180 ft).

In April 2014, the B-173A-8 exploratory well on NW B-173A flowed 2,246 b/d of oil during a conventional test from Mukta pay.

Development involves installation of a wellhead platform, associated pipelines, and drilling of three wells. ONGC expects the field to come onstream in February 2019, with production reaching a peak of 2,870 b/d of oil and 56.3 MMcf/d during 2019-20.

Both oil and gas will be evacuated through the existing Neelam process facilities.

ONGC has discovered more oil and gas in the Western offshore basin on a shallow-water structure in the Panna formation.

The B154N-1 (B-154N-A) was drilled in the Bombay Offshore seven-year PML license to a depth of 3,417 m (11,210 ft), flowing around 72 b/d of oil and 16 MMcf/d through a ¼-in. choke.

The result has opened up the potential for further exploration in the area north of B154, and should facilitate conversion of the seven-year PML to a long-term regular license.
