CB/OS-2 Block Cambay Basin, Western India (Cairn, Oil & Gas vertical of Vedanta Limited is the operator with 40% participating interest)
Located on the western coast of India, Cairn’s operations in CB/OS-2 block are centred on the Lakshmi and Gauri oil and gas fields. Gas production commenced from the Lakshmi gas field in 2002 and in 2004 from the Gauri field. In 2005 Gauri commenced crude oil production. Exploration, development and production in the CB/OS-2 block is governed by a PSC that runs until 2023. This is developed in partnership with ONGC and Tata Petrodyne Limited.
Since inception in 2002, Cambay has produced approximately 22 mmbbls of crude and over 223 bcf of gas. Application of advanced geophysical tools have transformed the CB/OS-2 block from a predominantly gas field to an oil field through the discovery of an oil leg. In the past Cairn’s technology driven approach helped in doubling the production of the block.As part of Cairn’s optimal asset utilisation strategy, the facilities have also enabled early gas production from ONGC’s North Tapti and Olpad fields, which are outside the CB/OS-2 acreage.
An 82-acre onshore processing facility at Suvali processes natural gas and crude oil from the Lakshmi and Gauri fields. It can process 150 mmscfd of natural gas and 10,000 bopd of crude oil. It includes three stage separator trains, three storage tanks with total capacity of 28,300 bbls as well as two 2.4 MW captive power generation plants. The processing plant and offshore infrastructure are certified to ISO 14001 and OHSAS 18001 standards.
