HOUSTON, Nov. 10
-- Reliance Industries Ltd., Mumbai, reported a Miocene oil discovery in the Cambay basin southwest of Ahmedabad, India, that Reliance said “is expected to open future potential within the block.”

CB10A-A1, Reliance’s fifth well, went to a total depth of 1,451 m in Part A of the two-part block and flowed at a rate of 500 b/d of oil from the Babaguru formation of Miocene basal sand on a 6-mm bean with 360 psi flowing tubinghead pressure. The well has a gross reservoir thickness of 15 m.

Block CB-ONN-2003/1, won in India’s fifth licensing round, has two parts in Gujarat. Part A to the west covers 570 sq km, and Part B to the east covers 65 sq km. Reliance, which holds 100% participating interest, named the discovery Dhirubhai-43.

Reliance has shot 3D seismic data over 80% of the block and 2D data over its entirety. Based on interpretation of the 3D data, Reliance has identified several prospects at different stratigraphic levels to fulfill the minimum work obligation under the production sharing contract.
