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.

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.”

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.

Gulf of Mexico: Quest Offshore Sees Bright Future for Deepwater GoM (USA)

The Gulf of Mexico, more than any other major deepwater region in the world, has experienced massive changes in the last five years with long-term implications for the future of the region and the GoM’s supply & demand effects on the global deepwater oil and gas market, Quest Offshore says in its report.

The worldwide financial crisis and subsequent recession, shale gas’ implications on U.S. natural gas prices and the aftermath of the Macondo incident have led to significant changes in the outlook for the region. Despite those overwhelming obstacles, the U.S. GoM’s future is bright with a pronounced recovery expected in all major market segments from drilling to subsea, floating production and marine construction.

Overall spending in the region is expected to increase significantly starting in 2013 up nearly 30 percent to $40 billion. Total expenditures are expected to reach a significant $167 billion in the 2013 to 2016 period. For the first time, 2012 is expected to represent an investment shift with deepwater CAPEX and OPEX spending surpassing that in shallow water. In the under developed ultra-deepwater frontier areas of the region, challenging technical and reservoir conditions will result in increased spending across the board, a trend expected to continue through the foreseeable future.

Five years ago the region was a mix of major and independent oil companies executing both oil and gas standalone and subsea tieback projects. In 2013 and beyond, Quest sees more oil dominance with offshore gas waning. Large international oil companies will play a larger role with the execution of standalone (hub) projects with niche-focused independents looking to infrastructure-led drilling around existing hubs and mega-independents continuing to grow their strategic portfolios in select basins.

In Quest Offshore’s latest market report, Quest Deepwater Review: Gulf of Mexico 2013 and Beyond, the reader will gain a comprehensive understanding of current trends and expectations from one of the leading deepwater basins, the U.S. Gulf of Mexico.

Leasing Activity Positive for Deep and Ultra-deepwater

Leasing activity is rightly seen as the furthest leading indicator for prospective oil and gas activity not only in the Gulf but throughout the world. Due to the relatively long lead times between leasing, drilling and production, leasing trends can be expected to provide insight on future activity for years to come. With one-third of active deepwater leases, oil majors and national oil companies are expected to continue to be the driving force for pushing the boundaries of the Gulf of Mexico’s development. Excluding Anadarko and Conoco, all recent frontier projects have been undertaken through operatorship’s of one of the majors or national oil companies (BP, Chevron, Exxon, Shell, Total, Statoil, Petrobras), and we expect this theme to persist moving forward.

Drilling Permitting on an Upward Trend

Drilling permit approvals are showing noticeable increases over the past six months with total counts back to pre-Macondo levels. As of the end of September there have been 78 new exploration drilling permits and 36 new development drilling permits approved over the year.

While raw permit counts are showing positive movement this year, the comparison in permits issued per project highlights the underlying cause for such steep increases in the first half of 2012. Multi-well projects (defined as five or more wells) have seen a record permitting pace since late 2011; examples of this trend include Chevron’s Jack/St. Malo Project, Shell’s Mars B Project, Hess’s Tubular Bells project, Chevron’s Big Foot and most recently the BP’s Atlantis North development, while true wildcat exploration permit numbers are still well below levels seen prior to the drilling moratorium.

Drilling Market Accelerating

Notable discoveries of ultra-deepwater fields in the Lower Tertiary continue to increase the reserve and production expectations for the region. The shift in the Gulf is most apparent in the floating rig market with four operators now possessing 50 percent of the contracted rig fleet. Ninety percent of rigs operating are high-spec and rated for ultra-deepwater.

Robust Outlook for Deepwater Development

Since 2008, the U.S. Gulf of Mexico has undergone a shift in project development mix from heavy in small, independent-operated subsea tiebacks to one that is grounded in fewer, larger subsea tiebacks and high-investment standalone developments developed by international oil companies and mega-independents.

This shift towards fewer, larger subsea tiebacks as well as increased FPS units will have profound effects on the future of the subsea sector as the hardware installed evolves as a direct result of fewer gas developments and deeper, more challenging fields. Subsea equipment manufacturers will experience fewer, but larger scope, award opportunities through the forecast period. As these developments move into more challenging areas, the value of these subsea production packages are expected to increase significantly as HP/HT trees and subsea processing become an enabler for these complex, capital-intensive projects.

This next wave of FPS developments is, for the most part, in ultra-deepwater and in more remote areas not currently connected to shallow water or onshore infrastructure. These developments will materially impact the pipeline and marine construction markets (SURF) as these production hubs are connected to existing export infrastructure through 2016 and beyond. The subsea tieback potential for these hubs is most likely to be seen in the latter half of this decade and into the following, with these latest hubs laying the foundation for the next generation of deepwater developments in the region.
