India’s state-owned Oil and Natural Gas Corp. (ONGC) has achieved first gas at 98/2 Block in Krishna-Godavari (KG) basin, offshore India, producing 14 months after work began. First gas involved tie-back of a single well in 4,265-ft water depths to existing Vashishta field infrastructure.
ONGC awarded the contract for combined subsea work on its KG-DWN-98/2 deepwater development off eastern India to a consortium of Baker Hughes, McDermott International Inc., and L&T Hydrocarbon Engineering, a subsidiary of Larsen & Toubro.
The $1.69-billion package included supply of all subsea production systems, including 26 deepwater trees, and the installation of subsea umbilicals, risers, and flowlines in 984-10,500 ft of water. Baker Hughes agreed to provide subsea hardware and precommissioning services. McDermott provided pipelay and construction vessels and engineering, procurement, construction, and installation services. L&T Hydrocarbon Engineering coordinated local work and services.
The well is the deepest opened by ONGC. Peak production rates are estimated at 16 million standard cu m/day of natural gas and 80,000 b/d of oil (OGJ Online, Oct. 4, 2018).
