HOUSTON, Jan. 21 -- An Indian and a Canadian operator have gauged another deepwater gas discovery on Block D6 in the Krishna-Godavari basin off eastern India.
F1, 10 km due east of the edge of the giant A1 discovery, cut 27 m of net gas pay and flowed 41 MMcfd of dry, sweet gas through a 60/64-in. choke on an equipment constrained, cased-hole drillstem test. Technical problems prevented evaluation of a deeper potential oil target.
Reliance Industries Ltd., Mumbai, and Niko Resources Inc., Calgary, drilled F1 to TD 3,630 m in 1,756 m of water in the Bay of Bengal. It is the block's fifth well.
Integrated 3D seismic and well interpretation indicates that F1 was drilled on a distinctly separate anomaly from A1, the original discovery on D6, Niko said.
A reserves report on A1 field, delineated by the block's first four wells, is expected from DeGolyer & MacNaughton consulting engineers in March 2003 (OGJ Online, Nov. 7, 2002).
Niko said it also completed the fourth and fifth wells on its Surat Block in western India. The fourth well flowed 1.4 MMcfd of gas from a shallow horizon, and the fifth well flowed a combined 2.4 MMcfd of gas from three shallow zones. The shallow play appears to cover 15 sq km on 3D seismic, Niko said.
