Expandable liners enhanced for more precise, reliable refracs

screen-shot-2018-01-30-at-10-12-52-pm

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

screen-shot-2018-01-30-at-10-13-15-pm

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

screen-shot-2018-01-30-at-10-13-55-pm

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

screen-shot-2018-01-30-at-10-12-18-pm

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...
