Gulf of Mexico: Halliburton’s ESTMZ System Used on Chevron’s Three Wells

Halliburton announced today the successful completion of three wells in the Deep Water Gulf of Mexico utilizing Halliburton’s Enhanced Single-Trip Multizone (ESTMZ™) FracPac™ System.

ESTMZ™ downhole tool system enables the operator to stimulate and gravel pack multiple production zones in a single trip. Designed for use in Dee Water and Ultra-Deep Water offshore completions, the ESTMZ™ system allows the highest treating rate with the greatest volume of proppant in the industry.

Halliburton developed the multi-zone completion technology in collaboration with Chevron U.S.A. Inc. The two companies conducted numerous system integration tests and two field trials to prove the technology.

The time savings realized for each of the three Chevron-operated wells completed with the ESTMZ™ system averaged 18 days, equating to approximately $22 million.

“ESTMZ™ system allows more reservoir to be stimulated in a shorter amount of time, thus increasing efficiency, reliability and production, which is key to the success of the Lower Tertiary,” said Ron Shuman, Senior Vice President of Halliburton’s Southern and Gulf of Mexico regions.

 “In addition, this system allows us to deliver a very aggressive stimulation with rates up to 45 barrels per minute and volumes greater than 400,000 pounds of 16/30 high strength proppant. We deliver this with weighted frac fluid and 10,000 horsepower per interval for up to five intervals, providing a total cumulative proppant volume of greater than two million pounds per well with one service tool. Having to make multiple runs in and out of the wellbore equates to a large expense for operators. The ‘single trip’ element of this system provides significant time savings with improved reliability and better asset optimization,” Shuman concluded.

Providing wellbore assurance through various critical operations such as wellbore cleanout, completion services, pumping and fluids also contributed to the success of these three wells. This integrated approach in planning and execution mitigated risks while promoting efficiency and providing an optimal conduit for the reservoir to flow.

The proven reliability of Halliburton’s ESTMZ™ tool system and the continual evolution of these smart technologies are critical to the changing landscape in the Gulf of Mexico. To date, Halliburton has successfully deployed nearly 20 ESTMZ™ systems around the globe including the Asia Pacific region.

Gulf Island Fabrication to Construct Jacket for Gulf of Mexico Project

Gulf Island Fabrication, Inc. , announced today that, through its subsidiary Gulf Marine Fabricators, it has received a Letter of Intent in anticipation of a contract for the fabrication of a 1200’ jacket from Walter Oil & Gas Corporation for its Coelacanth Project located at Ewing Bank 834 in the Gulf of Mexico.

Revenue backlog and man-hours associated with this project will be included in the Company’s consolidated backlog and will be reported when the Company announces its earnings results for the year ended December 31, 2012.

Gulf Island Fabrication, Inc., based in Houma, Louisiana, is a fabricator of offshore drilling and production platforms, hull and/or deck sections of floating production platforms and other specialized structures used in the development and production of offshore oil and gas reserves.

InterMoor Completes IRIS Installation and Recovery for Apache in Gulf of Mexico, USA

InterMoor, an Acteon company, has completed an installation and recovery project for Apache Deepwater LLC (Apache) in Mississippi Canyon Block 148, Well 5 in the Gulf of Mexico.

The work scope included the overboard, wet transfer, deployment and recovery of a 30-ton interchangeable riserless intervention system (IRIS) owned by Blue Ocean Technologies. InterMoor undertook the work in water approximately 168 meters deep from Cal Dive’s Uncle John semisubmersible vessel.

InterMoor delivered the project using its compensated anchor handler subsea installation system (CASIM) which reduces heave motions relative to vessel motions. CASIM units are pre-charged at the surface to deliver the needed heave compensation for the load at depth. InterMoor’s proprietary CASIM method requires less deck space and demands fewer deck operations than the traditional buoy-based heave-compensated landing system. The company also provided the associated rigging equipment and a technician to help facilitate the subsea compensation.

“Apache selected InterMoor for this project on the basis of our service record, the fact that we had the necessary equipment available and because of our experience in subsea operations of this kind,” said InterMoor project manager Jacob Heikes. “Although we have used CASIM to deploy and recover many types of subsea equipment, this is the first time that we have used CASIM for IRIS deployment and recovery, and the project’s success shows that this proven installation method is suitable for a wide range of subsea equipment.”

Titanium Explorer Drillship Starts Petrobras Contract in U.S. Gulf

The ultra-deepwater drillship, Titanium Explorer, started  its drilling contract with Brazil’s Petrobras in the U.S. Gulf of Mexico, on Friday, December 7. 

The Titanium Explorer, formerly known as the Dragonquest, owned by Vantage Drilling, is contracted for eight years.

Under the contract, Brazilian-state controlled oil company Petrobras has the right to re-locate and utilize the Titanium Explorer on a worldwide basis.  Expected revenues over the eight-year contract term, excluding revenues for mobilization of the rig and costs escalations, are approximately $1.6 billion.

The drillship is a self-propelled, dynamically positioned vessel suited for drilling in remote locations because of its mobility and large load carrying capacity. It is currently equipped for drilling in water depths up to 10,000 feet, and is designed to drill in water depths up to 12,000 feet.

Noble Energy Makes Oil Discovery at Big Bend Prospect in U.S. Gulf

Noble Energy, Inc.  today announced a discovery at the Big Bend exploration prospect in the deepwater Gulf of Mexico. The well, located in 7,200 feet of water on Mississippi Canyon Block 698, was drilled to a total depth of 15,989 feet. Open-hole logging identified approximately 150 feet of net oil pay in two high-quality Miocene reservoirs.

Charles D. Davidson, Noble Energy’s Chairman and CEO, said, “The discovery at Big Bend is an exciting follow-up to our recent success at Galapagos. The well results appear at least as good as our pre-drill mean resource expectations and de-risked our offset prospect Troubadour. The combination of excellent reservoir properties, fluid characteristics and our high working interest in this project will contribute significant production and cash flow for our business.”

Noble Energy operates with a 54 percent working interest in Big Bend. Other interest owners are W&T Energy VI, LLC (a wholly owned subsidiary of W&T Offshore Inc.) with 20 percent, Red Willow Offshore, LLC with 15.4 percent and Houston Energy Deepwater Ventures V, LLC with 10.6 percent.
