Often it is too difficult to create the fault conditions necessary for training a predictive maintenance algorithm on the actual machine. A digital twin generates simulated failure data, which can then be used to design a fault-detection algorithm. 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 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.
In addition to the well-recognized elements of digital transformation such as real-time monitoring, remote intelligence, and extraction of insights from data, there is a need to evolve the industry hardware through application of enhanced edge computing. Unlike shale, deepwater plays—which are highly front-loaded investments with long project cycles—will be least affected by the current round of severe investment reductions. Large offshore plays in safer regions have become essential elements of the core business of large oil and gas players. In 2004, US oil production was in decline, Facebook did not exist, and attitudes toward climate change were in flux. Despite the global downturn, the long-term transition to net zero presents a major opportunity to create new multibillion industries based around the North Sea. Cross-sector collaboration and major state/private sector intervention, together with strong leadership, will be key.
The complete paper demonstrates the benefits of honoring data measurements from a multitude of potential sources to help engineers do a better job of including more diagnostics into routine operations to provide additional insight and result in improved models and completion designs. This paper updates a previous case study and presents the results of actual implementation of an optimized steam-injection plan based on the model framework. By measuring which tests best predicted the fractures observed at the Hydraulic Fracturing Test Site, Laredo Petroleum developed a method it hopes will improve fracture modeling in other places. In the complete paper, a new, fully coupled implicit tool was used to model an onshore Omani asset with multiple reservoirs, each featuring different fluids and multiple networks. The complete paper aims at a better understanding of the effect of channel content in complex fluvial channel systems on well-test-derivative responses.
Looking to market your technology? Engage partners, pursue all paths, and learn to catch smaller fish. Its reward for years of struggling to adapt to low prices and weak demand for its oil and gas has been an epic crash. Canadians selling change say it is time to consider possibilities that seemed inconceivable in the past. Many confuse “an” innovation model for “the” innovation model, and we have confounded innovators with entrepreneurs.
The complete paper reviews the results of gas hydrate engineering and production testing studies associated with northern Canada and Alaska. Automated image-processing algorithms can improve the quality and speed in classifying the morphology of heterogeneous carbonate rock. Several commercial products have produced petrophysical properties from 2D images and, to a lesser extent, from 3D images. The complete paper provides an approach using machine-learning and sequence-mining algorithms for predicting and classifying the next operation based on textual descriptions. Imagine the time when we are no longer concerned about the digital-transformation issues we face today, such as data availability, security, and many others. This would be the time when companies make the best out of digital infrastructure. This era might be here sooner than expected. The complete paper describes the hurdles that have prevented single-trip installation of upper and lower completions in the complex world of subsea and deepwater applications and examines the processes, technologies, and risk-mitigation steps that took a concept from pilot to successful deployment. Specifically targeting ingrained thinking, the selected papers demonstrate the game-changing results that can be achieved even when targeting long-established norms. They demonstrate everything that our industry should be proud of and what we strive for. With reduced new unconventional well activity, practices such as frac-hit mitigation—pressurization of parent wells during child-well fracture stimulation—have become increasingly important to reduce parent-well proppant cleanouts as well as to maximize production from both parent and child wells. Sand control has evolved over the years; however, the fundamentals of screen sizing have not changed.
The proposed restructuring plan aims to eliminate about $74 million of the company’s debt. For the upstream industry, where improvement in efficiency or production can drive significant financial results, there is no question that the size of the digital prize is huge. In this study, the authors use a quantitative seismic interpretation work flow (QSI) based on a rock-physics template in estimating the uncertainty of the geochemical properties of organic mudrocks of the Shublik formation of the Alaskan North Slope. In this paper, the authors propose a least-squares Q migration (LSQM) method that combines the benefits of both LSM and Q prestack depth migration (QPSDM) to improve the amplitude fidelity and image resolution of seismic data. This paper demonstrates how maintaining investment in high-quality 3D seismic during the last downturn, together with selective exploration, quality geoscience, application of new technologies, and efficiently maturing discoveries to early cash flow, was successful in sustaining future production.
After 2 years of testing, Shell is going all in on using high-flying technology to catch methane leaks to reduce its overall emissions to less than 1%. Just 3 years after its landmark merger, GE has announced that in the next 3 years it plans to sell of all its remaining shares in Baker Hughes. A lot about the blowout preventers used for offshore drilling has changed since Macondo in 2010, but the essentials remain. This evolution serves as a case study on why some oilfield technology is hard to change. Halliburton and Schlumberger write-off billions in asset value and signal that more job cuts are coming during the second quarter.
Phase 1 involved a feasibility study for a facility capable of capturing 750,000 tonnes of carbon dioxide annually. The next phase will explore building a facility capable of more than twice that amount. Winning innovators focused on environment, safety, and operational efficiency. Operators celebrate first major deepwater project sanctioned since the early-2020 oil crash. Nearly everything’s on the table as companies aim to shore up portfolios by curtailing investments and dumping low-priority assets.
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.
