S1 and Vashista fields are free gas fields located 30-35 km off Amalapuram, Andhra Pradesh in water depths ranging from 300-700 meters with in-place reserves of estimated 19.692 BCM of gas to be realized through 4 wells, connected through dual 14” pipelines tied back to onshore terminal at Odalarevu in coastal Andhra Pradesh. Onshore Terminal at Odalarevu has capacity to process 6 MMSCMD gas with a provision for expansion up to 10 MMSCMD.

Integrated Development of S1 Vasishta fields included building of Gas processing facilities at Onshore terminal, drilling and completion of 4 deep water wells, engineering, procurement, installation and commissioning of dual 14” Pipelines and Umbilicals and other associated subsea structures to transport the gas from the ocean floor to the Onshore Terminal at Odalarevu. Connecting subsea deep-water gas wells to onshore terminal through a network of underwater pipelines and control Umbilical had been one of the most strenuous tasks. About 86 KM of 14” pipelines were installed on seabed in offshore and about 8 KM on land.
