ENSCO has received contract extensions from Apache that will keep jackups ENSCO 86 and ENSCO 87 with the operator thru 2010. The new term for ENSCO 86 is effective from July 31, while the new period for ENSCO 87 began May 23. ENSCO 86 is currently working in Vermilion 78, and ENSCO 87 just began work in Main Pass 296. The rig likely will also have work in Main Pass 140 and in the West Delta area later in the year. The two extensions now give ENSCO five of seven marketed jackups in the Gulf with contracts that run through 2010. ENSCO 75, also with Apache, and ENSCO 82 and ENSCO 68, both with Chevron are the other three.
Seahawk Drilling reports jackup Seahawk 2504 will finish its contract with Mariner Energy around the end of May. At present, no follow-up work is in place, but Seahawk intends to take the rig to West Cameron 38 for seven to ten days of surveys and repairs. After that, the company expects to have work for the rig. Seahawk also will likely have multiple contracts signed possibly this week for idle jackup Seahawk 3000. Repairs to the rig have been pushed back slightly and are now expected to be completed by June 10. The company’s only jackup affected by the recent permit moratorium appears to be the Seahawk 2004. It is understood that Dynamic Offshore does not have a permit secured for its planned well in Vermilion 196. As a result, the rig will likely go idle for a brief period after it completes its current contract with Arena Offshore around the end of the month.
Pride International newbuild drillship Deep Ocean Ascension has reached Curacao and after a crew change will continue its voyage to the U.S. Gulf. The rig is expected to arrive offshore Galveston later this week, after which it will complete acceptance testing prior to starting its five-year contract with BP in August. The next delivery for Pride will be the drillship Deep Ocean Clarion, scheduled to be completed by Samsung Shipyard in the third quarter this year. It also has a five year contract in the U.S. Gulf with BP starting in the first quarter of 2011. Both newbuilds are rated to drill in up to 12,000 fsw and have rated drilling depths of 40,000 feet.
Noble Drilling newbuild semi Noble Danny Adkins is scheduled to begin its 1,348-day contract with Shell by the end of May. The rig’s first assignment will be development drilling in Shell’s Perdido field in Alaminos Canyon 857. The field’s SPAR platform lies in 7,817 fsw and is the deepest producing facility in the world. The structure began production in March and will also process production from the Great White, Silver Tip and Tobago fields. To date, five development and one injection well have been drilled in the fields, although it is expected that ultimately 35 wells will be drilled between the four fields. The SPAR is designed to process 100,000 b/d of oil and 200 mmcf/d of natural gas.
Rowan has finished its contract with Devon Energy with jackup Rowan Alaska in Eugene Island 337 and the contractor has decided to cold stack the rig. As previously reported, two potential work locations for the jackup were not approved for hurricane season, leaving it with no follow-up work. The rig will join the Cecil Provine as Rowan’s only two cold stacked units.
