The find has been made in well number GS-15#9, being drilled on the GS-15 prospect, southwest of the Ravva field, also discovered by ONGC in 1987. It is located approximately 12 kilometers from the Amalapuram coast.
The well was spudded on May 28, 2005 at a water-depth of 17.8 meters with a target depth of 2500 meters. At the present depth of 2000 meters, it has indicated a significant hydrocarbon column (pay zone) of around 45 meters in the interval of 1684 meters to 1760 meters.
While most of this is Gas, the lower interval could comprise of an Oil leg.
The location has been drilled on its prospectivity evaluation being similar to the adjoining Ravva field, using the latest 3 D Ocean Bottom Cable (OBC) seismic acquisition program.
ONGC has already taken up the country's first integrated deepwater development, with smart well technology, in the G1-GS-15 area. The open architecture of this 'digital' development will facilitate early production from the new field, once the appraisal is completed.
