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.
Helix Energy Solutions Group Inc. (HLX) is turning into a takeover target after streamlining the company to focus on its expanding operations for offshore oil-well support.
The Houston-based company agreed last month to sell its oil-and-gas unit and earlier exited a pipe-laying business, helping Helix reduce debt and center its operations on deepwater vessels and robotics for well maintenance. The divestments make the $2.2 billion company more appealing to a potential suitor such as Aker Solutions ASA (AKSO) or Technip SA (TEC) that may want to expand in marine contracting, said Capital One Financial Corp.
Helix also may attract other oilfield-services providers, according to Stephens Inc., while Iberia Capital Partners LLC says a rig owner such as Diamond Offshore Drilling Inc. (DO) could be interested. Even after Helix’s moves led to a 31 percent gain in 2012 that beat U.S. energy equipment and services stocks, the company trades at a 23 percent discount to its closest competitor Oceaneering International Inc. based on this year’s estimated earnings, according to data compiled by Bloomberg.
“It’s a cleaned-up company,” Trey Stolz, an analyst at Iberia Capital in New Orleans, said in a telephone interview. “Helix would be attractive as an add-on for existing offshore service providers to immediately get a head start on the well intervention side. It’s the next step forward in further specialization of the offshore equipment.”
Terrence Jamerson, director of investor relations at Helix, didn’t return phone or e-mail messages seeking comment.
Helix, which traces its roots to a group of oilfield divers in the 1960s, evolved into an offshore energy company with operations spanning deepwater construction, oil-and-gas production and well maintenance and repair.
The company in October said it sold off its pipe-laying vessels and in December announced that it had agreed to sell its oil-and-gas unit as part of a plan to shift its focus toward so- called well-intervention services. This business, which encompasses undersea well maintenance, salvage and repair using floating vessels and robotics, is more profitable than pipe- laying while requiring less capital outlays than are needed for exploration and production, Chief Financial Officer Anthony Tripodo told investors during a presentation in November.
The asset sales spurred gains in Helix shares that contributed to the biggest advance last year among the 11 members in the Standard & Poor’s Midcap Energy Equipment & Services Index. The stock closed yesterday at $20.86.
By helping to center Helix’s operations on a single, growing business, the disposals also have bolstered the company’s allure as a potential takeover target, said David Streit, an Appleton, Wisconsin-based equity analyst at Thrivent Financial for Lutherans. The firm oversees about $76 billion in assets, including Helix shares.
“This focuses the company and provides potential acquirers with a much more focused and simpler package of assets,” Streit said in a phone interview. The sale of the oil-and-gas unit “removed the last major impediment to an acquisition. The balance sheet will be net cash positive after the divestiture of the business is complete. And beyond that it’s a very straightforward and clean business.”
Including its current net debt of $589 million, Helix’s enterprise value as of yesterday was 6.64 times its 2013 estimated earnings before interest, taxes, depreciation and amortization, according to data compiled by Bloomberg. The multiple for its Houston-based rival Oceaneering International (OII) was higher at 8.64 times this year’s estimated Ebitda, the data show.
“It’s trading at a multiple out of whack with other offshore asset-based service companies,” Iberia Capital’s Stolz said.
In its streamlined form, Helix may appeal to some contractors already operating in deepwater oil fields, Stolz said. The addition would give them a leg up as demand grows for well-intervention services, which use equipment sent down from vessels on the water’s surface to tap into aging wells on the sea floor and boost production.
Well-intervention vessels are in demand because they’re a cheaper alternative to drilling rigs, which have long been the standard and are now able to charge near-record leasing rates due to higher oil prices, Stolz said. The market for well intervention could experience growth similar to the past five years, when the number of aging wells nearly doubled to 3,500, he said.
Aker Solutions, a Lysaker, Norway-based oil-services company with well-intervention operations, could be a potential suitor for Helix, said Joseph Gibney, a Houston-based analyst with Capital One. The $5.8 billion company has a fleet of three deepwater well-intervention vessels, according to its website.
Paris-based Technip, with a market value of $13 billion, also could be a logical buyer because of its experience working in deep waters offering construction and engineering services for oil fields, Gibney said.
Ivar Simensen, a spokesman at Aker Solutions, declined to comment on whether the company is interested in Helix. Christophe Belorgeot, a spokesman for Technip, didn’t respond to an e-mailed request for comment.
Other oilfield-services companies may want to buy Helix to augment their businesses and gain technical expertise, said Michael Marino, an analyst at Stephens Inc. in Houston. Rig contractors such as Diamond Offshore may be interested in Helix as a way to recapture some of the work lost to lower-priced well-intervention vessels, Gibney and Stolz said.
Darren Daugherty, a spokesman for Diamond Offshore, declined to comment on whether the company is interested in Helix.
With Helix now focused on well intervention, the company could look to stay independent or even seek out acquisitions itself, said Todd Smurl, president and chief investment officer of Houston-based Ascendant Advisors.
“It might put them in play down the road but now they might actually be strong enough to be an acquirer as opposed to being acquired,” Smurl said in a phone interview. What’s more, after the stock rose 19 percent in the past month alone, “it’s not the screaming bargain it was,” he said.
Still, Stephens’s Marino estimates the company could fetch $25 in a takeover, a 20 percent premium to yesterday’s close.
“A takeout at those levels doesn’t seem crazy,” said Marino, who recommended that investors buy the stock after Helix announced plans to sell its oil-and-gas unit. “It makes a lot of sense for someone who wants to increase their presence internationally and offshore.”

Specialist bolt tensioner manufacturer Boltight Ltd has put together a new tool hire service that allows customers to trial hydraulic bolt tensioners, hydraulic nuts, pumps and ancillary equipment before making a final decision on whether to buy the equipment. The costs of hire can then be offset against the final purchase price.
The ‘try before you buy’ initiative has been launched in response to growing interest from companies from a wide range industry sectors who are contemplating making the switch from older types of legacy tools to the latest bolt tensioning technology.
Offshore oil and gas companies are increasingly using hydraulic tightening systems for subsea applications and working on compact flanges. The tools offer the end user a quick, precise and reliable means of bolt tensioning in difficult conditions, making it much easier to work quickly and achieve even flange and gasket compression.
Boltight’s tools are a popular choice because they are lightweight, easy-to-use, flexible and reliable. All the products are manufactured to exacting standards to strong and robust designs to ensure durability and a long operating life. The tools use the latest technology like low friction long life composite material seals that need little maintenance and simplify piston retraction. In addition, Boltight is able to provide comprehensive product and application support and technical back up at all times.
Explained Boltight director Fred Heaton: “We believe the best way to appreciate how far bolt tensioning technology has moved forward in recent years is to use these tools in a day-to-day workplace environment. Customers can conduct their own technical trials and compare our bolt tensioning tools with their existing equipment. If they like what they find, we can agree a special purchase price that takes into account the initial hire costs already incurred.”

Sep 13, 2012 – The Gurame SE-1X well is expected to spud towards the end of September, according to MEO Australia. Success of the appraisal well could lead to early development of the Gurame oil and gas field situated offshore northern Sumatra in the Seruway PSC. The well was identified via 3D seismic as the lowest risk drill-ready candidate with the highest potential for commercial development. Drilling will be undertaken by the Hercules 208 (200′ MLC). Two attractive targets in the well, the Baong and Belumai reservoirs, are expected to be naturally fractured and gas bearing. These attributes should improve the possibility of achieving commercial flow rates. MOE maintains a 100% interest in Seruway.

Sep 12, 2012 – Shell’s much anticipated Chukchi Sea drilling campaign is underway marking the first attempt in 20 years to explore offshore U.S. Arctic petroleum resources. Currently, the Noble Discoverer (mid-water drillship) is being used to drill the mud line cellar and top-hole sections of the first well. This is expected to take two weeks, after which the Discoverer will either continue drilling the Burger prospect or will move to another location to drill the top-hole section. Part of that decision will rest on whether or not the company is able to obtain a permit to drill past the surface sections into the oil bearing portion of the well. Shell has plans to drill three wells in the Chukchi Sea and two wells in the Beaufort Sea if the weather cooperates.

Aug 17, 2012 – Premier Oil reported that the Chim Sao North West appraisal well, CS-3X, has reached a total depth of 13,894 feet (4,235 meters). The well has been plugged and abandoned after encountering oil shows in the Middle Dua sands. The appraisal well was drilled to determine whether the Chim Sao North West discovery extended into a separate fault segment to the north. The well targeted the Upper and Middle Dua sands. While 443 feet (135 meters) of sandstone reservoir were penetrated in the Upper Dua interval there was no indication of hydrocarbons. In the Middle Dua interval 541 feet (165 meters) of sands were drilled, but only oil shows were encountered. The CS-N17XP well, which was completed immediately prior to the appraisal well, was drilled to produce from the North West extension to the Chim Sao Field. That well was brought on-stream earlier this month with initial extended production test rates averaging 4,000 barrels of oil per day from four Upper Dua reservoirs.
