McDermott International McDermott International has achieved the early first gas on the Oil and Natural Gas Corporation’s (ONGC) 98/2 block in the Krishna Godavari Basin, offshore India.

Awarded in October 2018, the largest subsea project in India brings together leading subsea equipment and services to provide ONGC with end-to-end project delivery.

The production from a deepwater well has been achieved in less than 14 months. The project has been undertaken with zero lost-time injuries on over 200,000 workhours.

The integrated subsea package includes supply of all subsea production systems (SPS), including 26 deepwater trees, and the installation of subsea umbilical risers and flowlines (SURF) at a water depth between zero ft to 4,265 ft (1,300 mtr).

Early first gas involved the tie-back of a single well to the existing Vashishta facility. At 4,265 ft, the first well that has been opened for early first gas is the deepest water depth opened by ONGC.
