Noble, GE collaborate to create digital rigs that leverage predictive analytics and digital twins to take maintenance off the critical path

Noble is currently monitoring seven systems onboard the Noble Globetrotter I: the BOP system, power system, drawworks, mud pumps, top drive, thrusters and dynamic positioning system. These systems were selected for monitoring because they had the greatest potential to cause downtime in the event of a failure.

To improve the efficiency of its asset management and operational productivity, Noble Corp announced in February that it had partnered with GE to outfit four of its high-specification rigs with an advanced data analytics system that can detect anomalies and potential failures weeks in advance. Seven key critical systems are now being monitored – the BOP system, power system, drawworks, mud pumps, top drive, thrusters and dynamic positioning system. Noble expects that it can achieve improved reliability and up to a 20% reduction in the maintenance spending on these systems as early as the second half of this year, according to Bernie Wolford, Senior VP Operations...

State of offshore rig market is all about rig supply – yet nobody knows how many offshore rigs there are in the market anymore

If the market returns to somewhere near its high demand of 397 jackups, then there will need to be 467 rigs in the fleet compared with today’s high supply number of 518, in order to achieve an 85% utilization rate. Bassoe estimates that the jackup fleet will shrink by 90 rigs over the next two years, while estimated attrition for semisubmersibles is 25. To achieve 85% utilization in the drillship segment, only four rigs would have to be removed, after removing the remaining non-competitive units. Bassoe believes that, even while it remains hard to forecast the supply side, scenarios that yield an 85% utilization are feasible.

What’s the state of the offshore rig market today? In four words, it’s not that bad. Sure, rig demand hasn’t risen as much as it was forecasted to do. When rigs do get drilling contracts, they don’t make much money. There are a lot of stacked rigs sitting around. There’s still a need for more contractor consolidation...

Fracturing innovations target improved equipment durability, optimized proppant placement

PackersPlus’ TREX QuickPORT IV sleeve has been deployed in the Permian Basin to address wireline and coiled-tubing issues in plug-and-perf in well laterals over 20,000 ft.

The oil and gas industry’s goals of reducing nonproductive time (NPT) and increasing production of unconventional resources are driving the evolution of hydraulic fracturing technologies. Especially as operators start to hit the natural physical limits of unconventional production, the need to optimize the fracking process has grown stronger, James West, Senior Managing Director for Oil Services, Equipment and Drilling with EvercoreISI, said. The optimization process differs by play, but overall, companies are looking for better well and fracture placement, as well as different sizing and staging of frac clusters...

Planning, temporary mitigation critical for industry to effectively comply with revised API standards

Traceability is a key theme across API 16A, 16AR and 20E, but wear and corrosion can often make bolted connections untraceable.

Over the past 18 months, there have been several revisions to the guidance, specifications and standards released by the American Petroleum Institute (API) relating to BOP and well control equipment (WCE). Previous industry incidents and issues prompted these revisions, as well as a more holistic approach to the design, inspection and traceability of this safety and environmentally critical equipment...

Roles, scope of real-time operating centers, support technicians evolve within modern drilling ecosystem

The need for increased competency among support personnel has expanded in recent years, along with the scope of real-time operations centers. Pictured is Canrig’s Houston training center.

The wider use of robotics, remote controls, real-time remote monitoring systems, artificial intelligence and other techniques are setting new standards of performance. The culmination of these engineering and technological efforts have yielded highly efficient, advanced-technology rigs. However, how should we develop and manage the support systems to leverage this modern drilling technology? Do we have the people, processes, tools and infrastructure needed to successfully apply these technologies?...

Offline operations in the Eagle Ford help Marathon Oil to reduce flat time on critical path of drilling rig

Adrian Binnion advised that strict consistency is necessary to maintain the economic benefit of offline surface casing running, due to the extra equipment costs incurred and the small margins associated with the operation. Marathon Oil also has field-tested offline production casing cementing on five wells in the Eagle Ford, which has also proven to be a technical success.

The beauty of unconventional drilling in North America today is that it is highly repetitive, which gives operators the opportunity over and over again to optimize their processes. The flip side of that coin, however, is that progress is typically incremental because the entire business of North American onshore drilling is already so highly efficient...
