Oilex Ltd. announced Monday that the Cambay Joint Venture has secured the Essar Rig 4 (Rig 4) for drilling Cambay-77H well in its Cambay Tight Hydrocarbon Project in the Cambay Basin, Gujarat, India through Essar Oilfield Services Limited. Rig 4 is one of several rigs proposed as part of the competitive tendering process conducted by Oilex with support from its Joint Venture Partner, GSPC.
Rig 4 is currently located in Dubai and arrangements are being made by Essar to mobilize it to the Cambay-77H site. The estimated mobilization time is 65 to 75 days with an anticipated well spud in mid 1Q 2014.
Cambay-77H is the second horizontal multi-stage fracture stimulated well in Cambay Field and has been designed with a 1,148 foot (350 meter) lateral section that will be fracture stimulated in four stages using the “plug and perf” methodology pioneered in North America. Each stage will have two fracture initiation points such that the lateral section of the well will have a total of eight fractures.
The critical 4.5 inch casing is on schedule for delivery during December 2013. It is anticipated that modifications to the Cambay-76H well location will commence prior to the end of 2013, allowing the site to be fully prepared before arrival of Rig 4. The Cambay-76H site will eventually be expanded to accommodate an additional three horizontal production wells as part of the contingent work program. Evaluation of the other tenders for services and equipment is ongoing and these remain off the critical path to spudding the well.
The Cambay-77H well plan requires an extended production test after completion of the fracture stimulations and arrangements are being made to sell off-spec gas with minimum processing. As previously announced, potential gas buyers have submitted Expressions of Interest for purchasing the off-spec gas and competitive bids have just recently been received with commercial evaluations to commence shortly. Dependent upon the production test results, which may last approximately 6 weeks or more, offspec gas will continue to be sold in addition to associated condensate.
Managing Director Ron Miller said:
"Securing a rig for Cambary-77H has been a priority for management and we are delighted to announce that Essar Oilfield Services will be providing Rig 4. We are also very satisfied with the competitive tendering results which are rationalizing the costs for Cambay-77H while not compromising recommendations received from independent engineering review of the Cambay-76H well. Rig 4 is an ideal rig for this well and we look forward to its arrival and
