SCHLUMBERGER will carry out the fracture stimulation contract on a well being drilled by Oilex in the onshore Cambay basin, in India’s Gujarat state.
The Cambay 77H well was being drilled by the Essar Land Rig 4 at the time of going to press, targeting 167 million barrels of oil equivalent from gross 2C contingent resources after reaching a total depth of 2,357 metres.
Oilex said the Schlumberger method would incorporate the lessons it learned from drilling the Cambay-76H well, as well as recommendations from a forensic engineering report.
The Cambay-76H horizontal well underwent a successful multiple staged fracture stimulation program along its 633 metre lateral section in 2012, but was suspended prior to testing due to downhole mechanical problems.
“It is a simpler, more robust design consisting of four stages with two fracture initiation points in each stage representing eight fractures in the 350 metre lateral section,” the company said. “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.”
Oilex managing director Ron Miller said the fracture stimulation would align with the well drilling program, adding that he was looking forward to working with the company.
The company said Schlumberger equipment and personnel will move to the site after drilling and completion operations were completed and the rig demobilised from site.
“The flow test is targeting commercial production from the first successful application of multi-staged fracture stimulated horizontal wells in India,” Oilex said.
The company recently raised A$6.8 million through a share issue to fund development of the well and other projects, issuing 94.75 million shares at 7.2 cents each to institutional and sophisticated private investors in order to raise the money.
Oilex holds a 30 per cent operating stake in the project, with UK-based Magna Energy holding a 15% stake. The remaining 55% is held by India’s Gujarat State Petroleum Corporation.
