Weir Oil & Gas introduces SPM SafeEdge ARC for remote setting and digital control of relief valves

Weir Oil & Gas announced the introduction of its SPM SafeEdge Automated Relief Vale Control (ARC) System. The intelligent valve system enables operators to remotely set and control SPM’s proven line of back pressure relief valves while monitoring treating-line pressure and helping prevent over-pressuring of treating iron...

Simulator-based training can help crews better prepare for complex MPD operations

By Linda Hsieh, Editor & Publisher As the drilling industry increasingly deploys managed pressure drilling (MPD) technologies, particularly in the deepwater arena, the potential for simulator-based training to step in and enhance both the safety and efficiency of such operations is also increasing. “When we look at the (knowledge) retention pyramid, the most efficient way for students is hands-on training, where we tie all the theory together with the practical,” Kim Laursen, Head of Well Control Services for Maersk Training, said in a presentation at the 2019 SPE/IADC International Drilling Conference on 7 March in The Hague, The Netherlands. Even when no new technologies like MPD are involved, the use of high-fidelity drilling simulators provide a safe and cost-efficient environment ...

Friction reduction system aids optimized bent-motor BHA to drill Vietnam’s longest basement section

Operator drilled section to TD and connected all targets despite extreme difficulties encountered in this complex wellbore By Son Bui, Thang Long Joint Operating Company; Ngo Huu Hai, Petrovietnam Exploration Production Corp; Nam Nguyen, Geoff Blackwell and Jake Tretheway, National Oilwell Varco Thang Long Joint Operating Company (TLJOC) was operating a well in the Cuu Long Basin offshore Southern Vietnam and needed to more effectively drill through a difficult section. Granitic basement drilling, where the formation is very hard (35 to 40 kpsi UCS), presented major challenges, as PDC cutters could not drill through the formation, very high levels of vibration were encountered, and rate of penetration (ROP) was limited. Despite the inherent risk of drilling such a well, TLJOC ...

Rotary steerable technology helps operators to beat AFE timelines in Granite Wash, Midland Basin wells

Point-the-bit RSS proves value in drilling of complicated wellbore trajectories in harsh environments, saves 8 days of drilling in one well’s lateral section By John Evans and Brian Jansky, Gyrodata One of the most significant drilling advancements in the petroleum industry in recent years has been the development of rotary steerable systems (RSS), which have proven valuable for directional and horizontal drilling. The first commercial use of Gyrodata’s RSS tool was in 1993. At that time, it was called an automated guidance system. These systems use specialized downhole technologies to replace conventional directional tools, such as mud motors. RSS technology allows guidance of the well trajectory while the drill string continuously rotates. This eliminates the need for an operator to ...

Overcoming learning curve leads to successful deployment of dissolvable plugs in Chinese shales

Understanding reasons why dissolvable frac plugs might not dissolve helps suppliers to address operational challenges, provide better operator experiences By Jack Wang, Vertechs Oil & Gas Technology Unconventional oil and gas development is on fast track. This is rapidly reshaping the technologies we know and continues to encourage performance, competition and innovation. But a learning curve must be overcome before a new technology can become an industry standard. This article will provide an introductory overview of dissolvable downhole technologies, particularly the challenges and failures that were encountered when they were introduced to the Chinese market in early 2016. Three years ago, China expanded the scale of its shale gas development. To maximize production, longer laterals were drilled. However, this came ...

Ocyan pushes forward with MPD/FMCD operations offshore Brazil

In October 2013, Ocyan reached an agreement with an operator to deliver MPD packages on four of its seven rigs. In this video with Leandro Rocha, Rig Performance Coordinator for Ocyan, from the 2019 IADC International Deepwater Drilling Conference in Rio de Janeiro, Brazil, on 20 March, he talks about the drivers for this agreement, lessons learned and areas of improvement for future floating mud cap drilling (FMCD) operations. Watch the video for more information.

Embedding MPD in well delivery plan can help to reduce overall well costs

The industry continues to see a shift in the planning and adoption of managed pressure drilling (MPD) practices. While not every well may need MPD, actively planning for it before drilling begins can provide cost reduction and other well construction benefits, even if MPD is not used at the well site, said Leiro Medina, VP of Technology with Beyond Energy, at the IADC Drilling Engineers Committee (DEC) Technology Forum on 12 March in Houston. In this video, Mr Medina discusses how MPD is being deployed to increase efficiency in Canada, the challenges to more widespread adoption of MPD, and the steps that companies can take to help MPD reach higher market maturity.

Reduce complexity in deployment of MPD will be key for wider adoption

Achieving true integration of  managed pressure drilling (MPD) as a standard in drilling plans will require the industry to making changes in control systems, hardware, processes and training. With these steps, MPD use will likely see wider adoption, said Dwayne Barnwell, Sales Manager with National Oilwell Varco (NOV) at the IADC Drilling Engineers Committee (DEC) Technology Forum on 12 March in Houston. In this video, hear how the NOVOS system could be used to integrate MPD functions to improve operations, and other ways the complexity and cost of running MPD can be simplified.
