The single independent riser (SIR) is a hybrid riser configuration optimized for ultradeepwater field development. The SIR is composed of a flexible jumper and a rigid part vertically tensioned by means of distributed or continuous buoyancy. This paper describes an automated work flow that uses sensor data and machine-learning (ML) algorithms to predict and identify root causes of impending and unplanned shutdown events and provide actionable insights. The Monument well represents the Norwegian operator’s first deepwater drilling project in US waters in 5 years. Transocean reported a long list of reasons why the deepwater drilling business is coming back strong.
Discussed are real-world examples of the less often considered but valuable environmental benefits delivered via MPD. The biggest drilling company appears interested in becoming the most innovative. It is testing inventions ranging from a blowout preventer that is not hydraulically powered to power systems designed like a hybrid car. The session will cover an area of growing interest, given increasing concern about wellbore integrity and well control. As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.
Personnel are returning to platforms in the Gulf of Mexico after Hurricane Sally was downgraded to a tropical depression late Wednesday, but the threat of another major hurricane remains as a tropical storm may form in the Gulf of Mexico today. The new well control rule is evidence that memories of the Macondo blowout remain a powerful force for caution. Despite the rhetoric on both sides of this hot-button issue suggesting big changes, the final changes were incremental. With the US Bureau of Safety and Environmental Enforcement as a cochair of the steering committee, SPE held a 2-day summit in April to discuss the development and implementation of an industrywide safety-data sharing framework. More precise measurement can create a dilemma.
The service companies plan to co-market an emerging well control system that can integrate with established managed-pressure-drilling components to enhance well construction safety and efficiency. A former chief operating officer at Exterran Corp. will take the helm of the Houston-based oilfield services company in October. Weatherford announced that Mark A. McCollum, president, CEO, and a director, has left the company, effectively immediately. With US oil prices struggling to top $25, oil companies and service providers are making deeper cuts this month to cope. The biggest come from Halliburton which may have shed 5,000 total jobs since the start of the year.
The service companies plan to co-market an emerging well control system that can integrate with established managed-pressure-drilling components to enhance well construction safety and efficiency. Wireline formation tests are a critical piece of the exploration and appraisal process, yet they come with a degree of uncertainty. The supermajor has tapped a new software developer to see if it can clear things up. The technology is being proven in millions of phones and homes across the world. Now, a small group of software startups wants to introduce chat bot technology to oil and gas professionals.
Traditionally, a wellhead system requires a drilling lockdown sleeve (LDS) during drilling operations to ensure that the seal assembly is rigid and prevents dynamic movement. By eliminating the LDS, however, the operator will save multiple trips into the well. The US Chemical Safety Board will investigate the blowout that killed three workers at a Chesapeake Energy well in central Texas. This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained. Fiber-optic technologies—distributed temperature sensing and distributed acoustic sensing—have been experiencing an ever-increasing number of applications in the oil and gas industry as monitoring systems.
For an industry that deals with a lot of both, the technology has many potential use cases. In the complete paper, the authors seek to understand the effect of triazine on the electrochemical response of a carbon-steel surface in a mixed-gas system. Energy Transfer pursued the stay and expedited appeal after its emergency request for a stay was denied by the US District Court for the District of Columbia. The court said it was mindful of the disruption the shutdown will cause but said the seriousness of deficiencies from the US Army Corps of Engineers outweighs the negative effects of shutting down the pipeline. The $20.7-billion agreement is the single-largest energy infrastructure investment in the region.
The service companies plan to co-market an emerging well control system that can integrate with established managed-pressure-drilling components to enhance well construction safety and efficiency. The next step is to move toward optimization, then automation. An intelligent drilling optimization application performs as an adaptive autodriller. In the Marcellus Shale, ROP improved 61% and 39% and drilling performance, measured as hours on bottom, improved 25%. A real-time deep-learning model is proposed to classify the volume of cuttings from a shale shaker on an offshore drilling rig by analyzing the real-time monitoring video stream.
The service companies plan to co-market an emerging well control system that can integrate with established managed-pressure-drilling components to enhance well construction safety and efficiency. This latest find means the offshore driller has averaged at least three new discoveries each year since it began drilling offshore Guyana where it plans to recover up to 8 billion barrels of crude. The next step is to move toward optimization, then automation. The new geothermal project development company will offer expertise in subsurface and drilling, project development, and risk mitigation. A new licensing round will open up 136 blocks in the Arctic Barents Sea.
