RIL makes fifth oil discovery in block CB-ONN-2003/1

Reliance Industries Limited (RIL) announced its fifth oil discovery in exploration block CB-ONN-2003/1 (CB 10 A&B), awarded under the NELP-V round of bidding. The block CB-ONN-2003/1 is located at a distance of about 130 kms from Ahmedabad, Gujarat, in the Cambay basin.

RIL drilled the well CB10A-J1 to a total depth of 1957 metres in Part A of the block, with the objective of exploring the play fairway in the Miocene Basal Sand (MBS) of Babaguru formation and Eocence Pays of Kalol formation. Hydrocarbon bearing zone was identified at a depth of 1376-1385.5 metres in the Miocene Basal Sand (MBS) of Babaguru formation. Conventional production testing was carried out in the interval of 1376-1381.5 m. The well flowed at a rate of 255 barrels of oil per day (bopd), through a 6-mm bean with a flowing tube head pressure of 180 psi.

The discovery is significant as this play fairway is expected to open more oil pool areas, leading to better hydrocarbon potential within the block.  The block covers an area of 635-sq km in two parts viz., Part A & Part B. RIL, as Operator, holds 100% Participating Interest (PI) in the block. While the entire block was covered with 2D seismic, nearly 80% of the block area also has 3D seismic coverage. Of the fifteen (15) exploratory wells drilled in the block by RIL so far, 11 are located in Part-A and the remaining 4 in the Part B of the block. RIL is continuing further exploratory drilling efforts in the block.

This discovery, named ‘Dhirubhai–48’, the fifth oil discovery in the block so far, has been notified to the Government of India and to the Director General of the Directorate General of Hydrocarbons. The potential commercial interest of the discovery is being ascertained through more data gathering and analysis.

This discovery supplements RIL’s understanding of the petroleum system in the Cambay basin in general and the block in particular. Based on interpretation of the acquired 3D seismic campaign in the contract area, RIL has identified several more prospects at different stratigraphic levels with upside potential.
