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.
The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings. The data analytics firm projects US dry gas output growth will shrink to 2 Bcf/D next year from 8–9 Bcf/D in 2018 and 2019. The complete paper describes a recent directional coiled-tubing drilling (DCTD) job completed for an independent operator in the Appalachian Basin.
JPT Technology Minute Poll: To Which of the Top Five UN Sustainability Development Goals Do You Think the Oil and Gas Industry Will Contribute the Most? The papers identified in the article cover sustainable development of oil and gas resources in various aspects. Flaring and emissions challenges have recently made news headlines around the world. The goal of this article is to engage you with this important topic by presenting a selection of recent SPE papers which address these challenges through various approaches. Operators face a dilemma in balancing the need for mud weight (MW) to remain below the fracture gradient to avoid losses, while also providing sufficient density to block influxes into the well. JPT Technology Minute Poll: Which Technology Would You Choose for Offshore Compression?
Discussed are real-world examples of the less often considered but valuable environmental benefits delivered via MPD. Managed-pressure drilling (MPD) challenges the conventional drilling paradigm, along with drilling-contractor and operator policies and standards. Conventional drilling practices for connections, flow checks, tripping, and well control have been long understood and standardized. More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
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.
It is a myth that blowouts only occur in high-pressure wells. Being able to investigate the blowout and kill potential on every well as part of the well construction process is an opportunity to increase safety awareness among drilling engineers. The industry worldwide has been swayed by the digitization wave. Extreme downhole conditions may lead to rapid degradation of pumped cement. The understanding of degradation of cement under such conditions is imperative to bring about improvements in the cement formulation.
