Offshore staff

NEW DELHI, India ONGC has notched two hydrocarbon discoveries offshore India’s east coast.

In the deepwater Krishna Godvari basin, the company drilled well KG-DWN-98/2-M-4 25 km offshore to a depth of 3,246 m (10,650 ft).

Based on subsurface geological, MDT/Mini DST and electro-log data, the well established six hydrocarbon-bearing zones with net pay of 78 m (256 ft). The objective in the interval 2,900-2,908 m (9,514-9,541 ft) tested conventionally flowed oil at 3,160 b/d and gas at more than 3 MMcm/d.

The discovery has opened a new up area for exploration and appraisal, ONGC claimed.

In block KG-OSN-2004/1, well KG-OSN-04/1-NASG-1, drilled in 69 m (227 ft) of water, 19 km (12 mi) south of Antarvedi in Andhra Pradesh, encountered significant gas volumes.

Subsurface geological, electro log data and MDT indicate net pay of 25 m (82 ft) within Pliocene sands. Object-I in the interval 1,727-1,737 m (5,666-5,699 ft) tested around 2.09 MMcm/d through a 24/64-in. choke.

This was the sixth discovery in the block.
