ONGC to Invest US$5 million in Deepwater
India’s Oil and Natural Gas Corp. (ONGC) has received approval from its board of directors for the development of its proposed US$5.1 million deepwater oil and gas project, offshore east India.
The field development plan (FDP) for Cluster 2 of the deepwater NELP Block KG-DWN-98/2. Cluster 2 consists of Cluster 2A and Cluster 2B, and is expected to reach a total oil and gas production of 23.53 million tonne, and 50.71 Bcm, respectively during the life of the project.
Cluster 2A has an estimated 94.26 million tonne of crude oil, and 21.75 Bcm of associated gas in place. ONGC anticipates production to peak at 77,305 b/d, and 3.81 MMcum/d of associate gas through 15 producer wells along with 12 water injection wells with a peak water injection rate of 9400 cu m/d from Cluster 2A oil fields.
Cluster 2B has an estimated 51.98 Bcm in place. Peak production of gas is expected to reach 12.75 MMcum/d from eight wells.
The peak daily production rate from the Cluster 2 works out to 16.89% and 27.60% of ONGC’s current production rate of crude oil and natural gas respectively, the company said.
Facilities at the project include one gas process platform with a bridge-connected living quarters platform, FPSO for processing, storage and evacuation of oil and gas from Cluster 2A fields, about 430km subsea pipelines, about 151km umbilicals, 10 manifolds, and onshore gas handling terminal. ONGC has also planned 35 drilling and completion wells, consisting of 15 oil producers, 12 water injection, and eight fee gas producers.
First gas is expected to be produced by June 2019, with first oil by March 2020, and overall completion in June 2020.
