MUMBAI, Oct. 10 -- India's state-run Oil & Natural Gas Corp. is planning to spend $1.43 billion for the second-phase redevelopment of Mumbai High South (MHS) field.
ONGC proposes to increase recovery from the field to arrest the 7-8%/year decline rate trend. The 25-year-old field currently is producing about 160,000 b/d of oil.
Plans also are afoot to enhance capacities of the company's 40 million standard cu m/day Hazira gas processing plant in Gujarat and its 12 million standard cu m/day Uran plant in Maharashtra by 5-6 million standard cu m/day each. The plant expansion is expected to cost about 16 billion rupees. The gas processed is produced from western offshore fields.
Sources indicate that ONGC plans to set up five production platforms and one processing platform in the second-phase redevelopment. The project is expected to be completed in 2010-11.
"The redevelopment of MHS will lead to recovery of an additional 21 million tonnes of oil from the field" during 2011-30, said a company official, speaking on condition of anonymity. Total recovery may increase to 34-35%, he said.
The 65-billion-rupee first phase, completed in May, included the drilling of 140 wells, installation of 10 well platforms, addition of pipelines, and upgrading of existing facilities.
On the proposed enhancement of the gas processing capacities, the official said, "We have already taken up a project to develop 28 marginal fields in western offshore, leading to an additional production of 15 million standard cu m of gas and 6 million tonnes of associated oil in the next 3 years. To accommodate this increased production, we are planning to set up two more trains at Hazira and Uran. It may take us another 3 months to finalize the project."
