Another Bassein platform on ONGC drawing board

Vol 20, PW 4 (03 Nov 16) Exploration & Production

ONGC wants to set up an additional $350m booster compressor platform at its Bassein gasfield on the west coast.

This report learns ONGC technical teams are preparing a feasibility report for the proposed platform called BCPB-3 that it wants installed in water depths of 60 metres with a capacity to handle a minimum 10m cm/d. In Ahmedabad, ONGC's Institute of Reservoir Studies is putting together estimates for gas recovery through the platform.

Once ready, the proposal is likely to be sent to the Board for financial approval sometime in March or April 2017 after which tenders will be issued. ONGC sources explain this project is needed because of depleting pressure and gas reserves at Bassein.

"One day well pressure will drop to 10-kg/cm2," we hear. "When that happens we will need to raise it to to 30-kg/cm2.

This new platform is to meet that eventuality." This new BCPB-3 platform will join established Bassein compression platforms BCPA, BCPB, BCPA-2 and BCPB-2. Soon to join them will be process/compression platform BCPA-3 complete with living quarters for 50 people, 13-km of oil/gas pipelines and a 9-slot BH unmanned wellhead platform contract awarded to L&T in June 2015 for $419m.

Through BCPA-3, ONGC believes it can recover another 19bn cubic metres gas from Bassein before 2030 when it predicts the economic life of the producing layers of the field will come to an end.
