ONGC Drills to More than 3,000 Meters Water Depth

ONGC's deepwater drilling campaign has crossed 3,000 meters water depth mark with the GSDW-2A-1 well being drilled by the Belford Dolphin.

The objective of the GSDW-2A-1 is to explore the hydrocarbon potential of Palaeogene carbonates having two shallow objects at 140 meters, top of carbonate, and 450 meters, intra-carbonate, below mud line respectively.

The well has been drilled and logged in 12 days as against 35-40 days that would have been needed to drill in similar conditions.

ONGC started the deepwater drilling campaign "Sagar Samriddhi" by spudding the well, GKDW-A-1, in 1,860 meters of water, the deepest water-depth well of India.

It launched the multi-billion dollar deepwater oil and gas project mid last year to explore the huge hydrocarbon reserves lying off both the east and west coasts of the country.

The project involves an investment of $2.6 million per day to search for one-third of the estimated 11 billion tons of oil and oil equivalent gas reserves lying unexplored in the deep waters.

Until now, gas has been struck at one well in KG basin while another well is being tested and the corporation is hopeful of finding gas there as well.
