New rotary steerable system designed for high performance in long laterals

Rotary steerable systems (RSS) are often built with sensors and capabilities that are “nice to haves” but not mission critical. Stripping away such non-essential features can lower the cost of an RSS without compromising performance, Paul Neil, Director of Steerable Technologies at National Oilwell Varco (NOV), explains in this video from the 2018 OTC in Houston on 2 May. NOV has developed the VectorEDGE RSS to deliver strong performance in long laterals in a cost-efficient manner. In this video, he discusses the key features of the system, including its closed-loop control system. He also describes the testing that has been done on this RSS in advance of its commercialization later this year...

New subsea valve actuator combines electro-hydraulic, electro-mechanical elements

Bosch Rexroth seeks to combine the best of electro-hydraulic and electro-mechanical actuator solutions with its new subsea valve actuator. The actuator works in the same way as an electric actuator, except that the customer provides the electric power to the system, while Bosch Rexroth provides the mechanical force to open and close valves via a hydraulic transmission inside the actuator, said Alexandre Orth, Senior Manager, Sales Industry Sector, Marine & Subsea Technologies, on 1 May at the 2018 OTC...

Wood Mackenzie: Operators taking a deliberate approach to offshore exploration and development

If the number of final investment decisions (FIDs) taken by operators is an indication of the health of the offshore market, then things are looking up. Wood Mackenzie anticipates that roughly 30 offshore projects will receive an FID in the coming year. This is roughly flat from 2017, when 32 projects were sanctioned, and a significant increase from 2016, when fewer than 15 projects received FIDs. The newly sanction projects this year are likely to be developed more quickly and at lower costs than pre-downturn projects, Julie Wilson, Research Director, Global Exploration at Wood Mackenzie, said at the 2018 OTC in Houston on 30 April...

Electric roller screw-activated choke delivers quick, accurate response when installed in manifold

Many existing hydraulic and electric chokes used to control surface backpressure during managed pressure drilling (MPD) weren’t specifically designed for use in MPD operations. Tolomatic set out to design a choke that would deliver a quick and accurate response in the face of changing pressure demands encountered during MPD operations. In this video from the 2018 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference on 18 April in New Orleans, La., Ryan Klemetson, Business Development Manager for Tolomatic, explains the drivers for developing ServoChoke, an electric roller screw-activated choke, and how it works. He also discusses the company’s collaboration with Pruitt Optimal to build the choke into Pruitt’s manifold, as well as the results observed when the manifold was deployed...

Condition monitoring system under development to predict wellbore seal failures

Often, operators aren’t aware that a wellbore seal needs to be replaced until a leak or loss of pressure occurs. AFGlobal is developing and testing a condition monitoring program for seals in an active wellbore sealing device to determine when a seal is nearing the end of its useful life before any leaks or pressure losses occur, leaving hours to spare before a change is required...

Operators, contractors must work together to define MPD-readiness, boost adoption of MPD

Over the years, operators have increasingly turned to managed pressure drilling (MPD) not only to manage narrow pressure windows but also to enhance kick detection and save rig time. During this downturn, in order to stand out from the competition, drilling contractors began outfitting more of their rigs with the equipment needed for MPD, Ben Pomford, Head of Drilling Solutions for Maersk Drilling, said at the 2018 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference in New Orleans on 17 April. In this interview with DC at the conference, he explains that while there’s an eagerness to make rigs MPD-ready, there’s also a lack of consensus on what exactly “MPD-ready” means. He also discusses how operators and contractors can come together through groups like the IADC UBO/MPD Committee to harmonize conflicting viewpoints on what constitutes MPD-ready and further drive MPD adoption...

Noble Drilling looks to ‘traveling MPD package’ to prepare multiple rigs for MPD

Operators are increasingly looking to their drilling contractors to supply the bulk or entirety of a drilling rig’s managed pressure drilling (MPD) package. However, outfitting a rig – much less a whole fleet – with such equipment can be cost prohibitive, especially in the current dayrate environment, Jason Custer, Mechanical Engineer at Noble Drilling, said at the 2018 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference in New Orleans, La., on 17 April. Other challenges Noble is addressing include training the rig crew to operate and maintain MPD equipment, as well as managing additional third-party personnel on the rig...

IADC UBO/MPD Committee to finalize training curriculum, establish categories for MPD-readiness

This year, IADC’s committee for Managed Pressure Drilling (MPD) and Underbalanced Operations (UBO) will continue its work on API recommended practices 92M and 92P. The former pertains to MPD with surface backpressure, while the latter relates to pressurized mudcap operations with a subsea BOP. Committee Chairman Andre Alonso Fernandes, Technical Advisor at Petrobras, provided an update on this work, as well as other projects the committee is pursuing, on 18 April at the 2018 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference in New Orleans, La. In this interview from the conference, Mr Fernandes discusses the committee’s ongoing work, as well as efforts to develop an MPD training curriculum and to define the readiness of different drilling rigs for MPD functions...

Proposed JIP would create standard for sensor verification and validation

As the drilling industry increasingly relies on sensor data to feed rig automation, it’s essential to ensure sensor accuracy. However, there is currently no industry standard for independently verifying and validating sensor accuracy, Maria Araujo, R&D Manager for Southwest Research Institute, said at an IADC Drilling Engineers Committee Technology Forum on 21 March in Houston. Southwest Research Institute is proposing a new joint industry project (JIP) to establish such a standard. In this video from the forum, Ms Araujo outlines the timeline and key deliverables of the first phase of this three-phase JIP, including prioritizing the sensors to be validated and verified. She also explains how companies can get involved in the JIP...

New acoustic listening platform equipped with full-spectrum sensors

Acoustic technology has been used in the oil and gas industry to detect leaks and evaluate cement bonding for years. However, the sensitivity of these technologies has been limited, so low-energy leaks weren’t always detected. At the 2018 SPE/ICoTA Coiled Tubing and Well Intervention Conference, Archer launched the VIVID acoustic listening platform, equipped with sensitive, full-spectrum acoustic sensors. In this video from the conference on 27 March, Peter Kleinbichler, Wireline Vice President of Sales and Marketing, discusses how the platform’s sensors enable it to detect a broad range of frequencies. This ability, he explains, allows the VIVID platform to not only verify the presence of cement but also detect the quality of the cement job. Further, he describes the testing performed on the platform at the International Research Institute at Stavanger...
