Oilex Ltd. announced Monday that the Cambay Joint Venture has awarded the fracture stimulation program for Cambay-77H in Cambay Production Sharing Contract (PSC) in the Cambay Basin, Gujurat, India to Schlumberger. Schlumberger was one of a number of international services companies operating in India that participated in the competitive tendering process. Oilex, as Operator, will be working with Schlumberger on the fracture stimulation program details for Cambay-77H which shall be implemented after the drilling rig has been demobilized from site.

The “plug and perf” completion design incorporates the lessons learned from Cambay-76H and recommendations from the forensic engineering report. It is a simpler, more robust design consisting of four stages with two fracture initiation points in each stage representing eight fractures in the 1,148 feet (350 meter) lateral section.

Subsequent to completing the four stages of fracture stimulations, the isolation plugs between the stages will be removed and Cambay-77H will then be flow tested to complete the proof of concept activities for the Cambay Joint Venture. The flow test is targeting commercial production from the first successful application of multi-staged fracture stimulated horizontal wells in India. This technique is widely used in North America and recognized as a key enabler
in the significant increase of domestic oil and gas production from tight reservoirs in the United States.

Managing Director of Oilex, Ron Miller, said;

“Schlumberger is a well-known and experienced service contractor for fracture stimulation work around the world and have an extensive fleet of equipment and capable personnel in India. Oilex looks forward to working with them to ensure a successful fracture stimulation program. Although awarded after the spud of Cambay-77H, the schedule for the fracture stimulation work will align to the drilling program as Cambay-77H is currently being directionally drilled to the 9.625 inch casing point.”
