India’s Oil & Natural Gas Corporation (ONGC) has achieved first gas from its Block 98/2 deep-water development in the Krishna-Godavari basin, offshore India.
Project engineering contractor McDermott International considers this to be the country’s largest subsea project so far.
The American engineering company secured the end-to-end project delivery contract from ONGC in October 2018.
Delivering early first gas involved tying back one well to the existing ONGC Vashishta facility.
McDermott’s package covered supply of all subsea production systems. These included 26 deepwater trees, and the installation of subsea umbilicals, risers and flowlines (SURF) equipment in water depths of about 1,300m.
The company said the water depth of 1,300m is the deepest of any ONGC operations offshore India.
