ONGC spuds first KG-DWN-98/2 project well

State-owned Oil & Natural Gas Corporation has spudded the first of 34 subsea wells planned in its US$5-billion KG-DWN-98/2 deep water oil and gas development.

The Vantage Drilling International Platinum Explorer drillship is drilling the KDG-A well to a target depth of 2,346 metres in 518 metres of water off eastern India.

In addition to the drilling, the project includes 425 kilometres of 6-22-inch pipeline, 150 kilometres of control umbilicals, an offshore process platform able to process 6.5 million standard cu m/day of gas, and a floating production, storage, and offloading vessel to process oil and gas.

Water depths are 300-1,400 metres. The FPSO will be in 413 metres of water.

ONGC expects the project to produce 78,000 b/d of oil and 15 million standard cu m/day of natural gas at peak. Flow will start in 2019 for gas and in 2020 for oil.

Of the planned wells, 15 will produce oil, eight will produce gas, and 11 will inject water.

Cluster 2A of the project will have peak production rates of 78,000 b/d of oil and three million standard cu m/day of associated gas.

Cluster 2B will produce 12.25 million standard cu m/day of free gas at peak.

ONGC expects production from the project to total 25 million tonnes of oil and 45 billion cu m of gas.
