Expandable liners enhanced for more precise, reliable refracs


Enventure has launched its enhanced versions of its ESeal RF and ESeal RFHT refrac expandable liners at the 2018 SPE Hydraulic Fracturing Technology Conference and Exhibition, held 23-25 January in The Woodlands, Texas. The Enhanced ESeal RF and ESeal RFHT provide 16% and 45% higher strength, respectively, than the original ESeal RF Liner. This has expanded the operating envelope for installations using higher treatment pressures and in higher temperature reservoirs, which could exceed 300°F. The liners now offer more predictable zonal isolation and better ID preservation, said Matt Meiners, Technology and Product Development Manager at Enventure. The enhancements were made in response to recent surges in refracturing programs as operators seek to increase production and estimated ultimate recoveries of shale wells. Watch ...

Coiled-tubing frac sleeve with collet locating system improve BHA placement in extended-reach laterals


Coiled-tubing frac sleeve systems are gaining popularity due to their ability to deliver stimulation treatments to a large number of stages in extended-reach laterals. However, many of these systems rely on depth correlation for bottomhole assembly (BHA) placement, which can be imprecise. As a result, these systems often cannot accurately locate sleeves once they’re installed downhole. In response to this challenge, Baker Hughes, a GE company, developed the Blitz coiled-tubing frac sleeve system, which was launched at the 2018 SPE Hydraulic Fracturing Technology Conference in The Woodlands, Texas. In this video from the conference on 23 January, Scott Sanchez, Product Line Manager-Unconventional Multistage Completion Systems, explains how the Blitz’s collet locating system enables more accurate BHA placement. He also discusses the results BHGE saw when the system was deployed for an operator in Alberta, Canada...

Self-drilling modules aim to help operators scale up operations, deliver consistency


To eliminate human error and reduce inefficiencies in drilling operations, AI Driller, an automation company that provides self-drilling applications, is gearing up to deliver a series of drilling modules, beginning with an ROP Module and Auto-Slider. The ROP Module, which is certified on National Oilwell Varco’s NOVOS platform, calculates the target weight on bit based on historical drilling data. The Auto-Slider, which is under field testing, applies autonomous directional drilling control for sliding with a conventional drilling motor based on inputs such as distance, inclination and release torque. Both technologies were presented at the IADC ART Spark Tank in December. In this video, DC speaks with CEO Marat Zaripov and COO Joel Dunn about the two modules and how they can ...

Four strategies to consider in rig reactivations


As the offshore drilling industry continues to face difficult economic conditions and an abundant rig oversupply, it’s important to take a strategic approach to rig stackings and reactivations. In a panel session at the 2018 IADC Drilling HSE&T Asia Pacific Conference, Adrin Shafil Bin Ahmad Nasir, Drilling and Completions Manager for Petrofac Malaysia, presented four strategies to consider: condition normalization, taking ownership of the project, creating a safety culture early, and developing strong relationships. Watch DC’s video with Mr Shafil from the conference, held 24-25 January in Ho Chi Minh City, Vietnam, to learn more about these four strategies...

Chevron announces oil discovery in deepwater Gulf of Mexico


Chevron has announced a significant oil discovery at the Ballymore prospect in the deepwater US Gulf of Mexico. Ballymore is located in the Mississippi Canyon area of the US Gulf of Mexico, approximately 3 miles from Chevron’s Blind Faith platform, in a water depth of 6,536 ft. The initial Ballymore well reached a total measured depth of 29,194 ft and encountered more than 670 ft net oil pay with excellent reservoir and fluid characteristics, according to Chevron. A sidetrack well is being drilled to further assess the discovery and begin to define development options. “The Gulf of Mexico deepwater is an integral part of our company’s long-term strategy,” said Jeff Shellebarger, President of Chevron North America Exploration and Production. “This discovery is an important addition to our portfolio, especially with its combination ...

Canadian oil sands production growth set to continue, despite lower investment


Oil sands production growth will continue through the next decade, but a slowdown is anticipated, with investment expected to remain lower than historical levels, according to a new research initiative by IHS Markit. “Oil sands production is akin to base-load power generation, but for the oil market,” said IHS Markit’s Executive Director Kevin Birn, who heads the Oil Sands Dialogue. “Once operational, oil sands facilities are largely unresponsive to the oil price, with production neither ramping up nor ramping down materially. And since oil sands do not have to overcome production declines, every incremental investment in new capacity—no matter how small—can result in growth.” Entitled Scenarios for Future Growth, the Oil Sands Dialogue report forecasts the outlook for oil sands investment and ...
