CAMBAY OVERVIEW
Located in the prolific Cambay Basin, the Cambay Asset is the most significant component of the Company’s portfolio, covering 161 km² (~40,000 acres) in Gujarat State, the industrial heartland of India.
The geology in the Cambay Asset is proven to contain hydrocarbons and has a prospective section of 2,800m. 36 wells have penetrated the Eocene Formation, a tight silt stone section with 16 vertical wells testing oil and gas to surface. The contract area is covered by a high quality 3D seismic survey acquired by Oilex in 2007. Oilex is committed to implementing proven North American technology to achieve commercial production from the Eocene Formation.
CAMBAY IN DEPTH
The national oil company, ONGC drilled the first well in 1958 and there have been a significant number of subsequent wells targeting conventional reservoirs in the Cambay Basin.
A discovery of oil in Ankleshwar structure in 1960 provided a further boost to the exploration in the Cambay Basin and out of 244 prospects drilled, 97 are oil and gas bearing.
Oilex became one of the first foreign companies into the basin when it farmed into a PSC with Niko and GSPC in 2005 as an operator with a 45% interest.

Between 2006 and 2011, the Company conducted an extensive work programme in the contract area, including 3D seismic, five wells and a study to evaluate the application of shale gas technology to the Eocene reservoirs. Netherland Sewell & Associates, Inc. (NSAI), conducted an independent assessment in 2011 which identified significant Contingent Resources and Prospective Resources.
Cambay-73 was originally drilled in 2008 with a single stage fracture stimulation and was subsequently shut in. During an extended production test in 2012 it had a peak production rate of 1MMscfd and 23.5 bbls of condensate.
