India’s Oil and Natural Gas Corporation (ONGC) has approved the Field Development Plan (FDP) for the development of fields falling under Cluster 2 of the deepwater block KG-DWN-98/2, in the Krishna-Godawari Basin offshore India, with plans to complete the project in 2020.
According to the company, the development will involve a capital expenditure of $5.076 billion.
The field will be developed with one gas process platform with a bridge connected living quarters platform for processing gas from free gas wells, FPSO for processing, storage and evacuation of oil/ gas from Cluster 2A fields, about 430 km subsea pipelines of various sizes from 6” to 22”, about 151 km umbilical and 10 manifolds, riser base manifolds and onshore gas handling terminal.
In addition, drilling and completion of 35 wells have been planned. Out of those 35 wells, 15 will be oil producers, 12 water Injection, and 8 free gas producers.
Production of first gas is planned by June 2019, first oil by March 2020, with overall completion in June 2020.
Cluster 2 of the Block has been divided into two parts, Cluster 2A which has estimated in-place reserves of 94.26 MMt of crude oil and 21.75 BCM of associated gas; and Cluster 2B, which has estimated in-place reserves of Free Gas of 51.98 BCM.
ONGC said that peak oil rate would be 77,305 bopd and 3.81 MMSCMD of associated gas through 15 producer wells along with 12 water injection wells with a peak water injection rate of 9,400 m3/d from Cluster 2A oil fields. Peak production rate of free gas is envisaged at 12.75 MMSCMD from 8 wells of Cluster-2B free gas fields.
Further, total oil and gas production planned is 23.526 MMt and 50.706 BCM respectively during the project life from the Cluster 2. 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.
