State-owned Oil and Natural Gas Corp (ONGC) plans to invest over US$ 8.8 billion in bringing to production its much-touted KG-basin oil and gas discoveries by 2018-19.

ONGC has divided 12 oil and gas finds in the block KG-DWN-98/2 or KG-D5 and gas discovery in an adjacent G-4 block the Bay of Bengal into three clusters to quickly bring them to production, a senior company official said. The 7,294.6 sq km deep-sea KG-D5 block has been broadly categorised into Northern Discovery Area (NDA - 3,800.6 sq km) and Southern Discovery Area (SDA - 3,494 sq km). The company plans to develop the 11 oil and gas finds in the NDA together with one gas find in G-4 block at an investment of US$ 8.843 billion, he said.

“The investment will be for drilling 45 development wells, an array of sub-sea pipelines carrying gas to a fixed platform for processing and a pipeline to carry gas from it to an onshore terminal. Oil will be transported to a floating production system (FPSO) that will transfer it to ships for taking to refineries,” he said.

ONGC plans to develop the discoveries in the block in three clusters -- 14.5 million standard cubic meters per day of gas for 15 years from Cluster-1 comprising of D&E finds of NDA in KG-D5 block and G-4 find in the a neighbouring area. Cluster-2A mainly comprises of oil finds of A2, P1, M3, M1 and G-2-2 in NDA which can produce 75,000 barrels per day (3.75 million tonnes per annum).

Cluster 2B, which is made up of four gas finds -- R1, U3, U1, and A1 in NDA -- envisages a peak output of 14 mmscmd of gas, with cumulative production of 32.5 bcm of gas in 14 years.
