India: Cambay tight sands well due multifracs

By OGJ editors
– A group led by Oilex Ltd., Perth, will drill a proof-of-concept horizontal well to a tight sand in Cambay field in India and conduct 2 months of tests following an eight-stage frac stimulation.

Cambay-76H, to spud in May 2011, is to have a 610-m lateral in the areally extensive Eocene Y zone reservoir at 1,800 m on the 161 sq km Cambay production sharing contract area. A rig is being moved from another location in Gujarat.

A data package for Cambay field “tight” reservoirs has been submitted to a US independent reserves certifier that expects to complete the certification process in May. Vertical wells have yielded gas-condensate from Eocene at subcommercial rates on the block, which is 10 km from India's gas grid.

Cambay PSC participating interests are Oilex Ltd., operator with 30% interest, Oilex NL Holdings (India) Ltd. 15%, and Gujarat State Petroleum Corp. 55%.
