NEW DELHI, India – ONGC has discovered gas and condensate in India’s shallow-waterWestern Offshore basin.

Well MBSO51NBA#1 was drilled in NELP block MB-OSN-2005/1 to a depth of 4,181 m (13,717 ft).

During a test, the 2,596.5-2,599.5 m (8,518-8,527 ft) interval in the Upper Oligocene Daman formation flowed 171,630 cm/d (6.1 MMcf/d) of gas and 93 b/d of condensate through a ½-in. choke.

The location is respectively southwest and northeast of the C-37 and B-9 finds, opening a large area for future exploration, ONGC claims.

Earlier this month, the company farmed out 26% of a deepwater exploration block in the Krishna Godavari basin offshore eastern India to Japan’s INPEX.

KG-DWN-2004/6, 300 km (186 mi) off the Andhra Pradesh coast, was awarded to an ONGC-led consortium under the NELP-VI licensing round. It extends more than 10,000 sq km (3,861 sq mi) in a water depth of around 3,000 m (9,842 ft).

ONGC has completed most of the Phase-I exploration program except for the drilling of one well. The company will remain operator with a 34% interest. Partners are GAIL (India), Gujarat State Petroleum, Hindustan Petroleum, and Oil India.

Last month, ONGC’Mumbai High North (MHN) production platform was officially inaugurated. It was installed next to the BHN platform in the Arabian Sea.

The new facility includes equipment for separation, compression, dehydration, and sweetening. It will add 48,000 b/d of oil and gas compression at 6.9 MMcm/d (243 MMcf/d) to output from the MH North field.

During the platform design program, ONGC also discovered the nearby B-series satellite field nearby, and opted to include facilities for processing B-series sour gas. When onstream this will add 1.6 MMcm/d (56.5 MMcf/d) of gas.
