ONGC’s KG Gas Field To Touch Peak In July 

The Government-owned Oil and Natural Gas Corp expects to scale peak output of about 5 million standard cubic meters per day from its Vashishta gas field in KG basin by July this year.

Vashishta and S1 gas fields, located in the Krishna- Godavari (KG) Offshore Basin off the east coast of India, began operations in September 2016. "We are producing 1.1 million standard cubic meters per day from the fields currently and hope to reach about 5 mmscmd by July," a senior company official said.

The fields were developed under a greenfield deepwater development project at an investment of USD 751.65 million. The Vashishta field is estimated to produce 9.56 billion cubic metres (bcm) over a period of nine years with peak production reaching 3.55 million metric standard cubic metres a day (mmscmd) during the first five years.

The S1 field is expected to deliver 6.22 bcm over a period of eight years with a peak production of 2.2 mmscmd for the first five years. As part of the Vashishta and S1 field development, ONGC is drilling four wells and shipping the gas from them through a sub-sea pipeline to an onshore terminal at Odalarevu in Andhra Pradesh, he said.

The Vashishta field lies in water depths varying between 500 meters and 700 meters and about between 31-35 km from the Amalapuram coast. The S1 field is located in water depths of between 250 meters and 600 meters, and approximately between 26k-29 km from the Amalapuram coast. While the Vashishta field is a free gas field with estimated reserves of 12.92 bcm, the S1 field lies to the east of G-1 field and is a free gas field with estimated reserves of 10.37 bcm.
