OREANDA-NEWS. April 26, 2012. ONGC Board in Meeting held on April 25, 2012 has approved investment proposal for Development of Western Periphery as a part of Mumbai High South Field, Phase III Redevelopment, at an estimated cost of 600.17 Crore. The project, scheduled to be completed by December 2014, is expected to result in incremental production of 1.031MMt of oil and 213.817 MMm3 of gas by March 2030. The project envisages installation of one 12 slot four-legged unmanned platform, drilling of 10 wells and associated modifications and pipelines for well fluid, gas lift and water injection.

 It may be noted that Phase-I of the Redevelopment project which was completed in 2007 helped significantly arrest the decline in production and increased it from level of 131,400 bopd in June 2001 to 173,000 bopd by beginning of 2007. The phase -II which was launched after the completion of Phase-I to further improve the recovery factor is in advance stage of completion and is expected to improve oil recovery to 34.5% by March 2030.
