"A piece of writing that has been copied from someone else and is presented as being your own work." "The unauthorized use or close imitation of the language and thoughts of another author and the representation of them as one's own original work." "Text recycling, also known as self-plagiarism, occurs when sections of the same text appear (usually un-attributed) in more than one of an author's own publications. The term'text recycling' has been chosen to differentiate from'true' plagiarism (i.e. when another author's words or ideas have been used, usually without attribution)." SPE expects that authors will credit all sources used in their writings and will not represent the work of another as their own.
Advanced machine-learning methods combined with aspects of game theory are helping operators understand the drivers of water production and improve forecasting and economics in unconventional basins. What Damage Is Wrought by the Rush to Shut In Wells? The Permian Basin is now influencing the upstream water market on the way down, while many questions swirl around the implications of unprecedented shut-ins. Autonomous Inflow Control Valve technology demonstrates significant benefits within first year. As operators feel the pinch of low oil prices, so, too, do their service providers.
The company said its goals underscore its strong environmental, social, and governance performance as it responds to rising global energy demand. In addition, it said, the goals are aligned with the United Nation’s Sustainable Development Goals. Working to lower sulfur dioxide and carbon monoxide emissions is beneficial from an environmental point of view, but it is not free. In fact, it comes with a substantial cost increase. This paper explores options for emission reduction at ADNOC’s Habshan gas-processing plant along with their costs.
Many two-phase and three-phase separators in the oil and gas industry continue to underperform. This article explores the weaknesses in different sizing methodologies and proposes manageable approaches to quantifying each. This paper provides details of comprehensive computational-fluid-dynamics (CFD) -based studies performed to overcome the separation inefficiencies experienced in a large-scale three-phase separator.
Mark Bothamley's series quantifying separation performance in the August-December 2013 issues represents a significant addition to the literature in two-phase separator design. Ken Arnold proposes additional areas of study to take our knowledge even further. In this second article of a three-part series, methods for improved quantification of operating performances of the gas gravity separation, the mist extraction, and the liquid gravity separation sections of gas/liquid separators are discussed. Setting optimal surface separation pressures are crucial for maximizing the surface liquid production from the wellstream feed. Where separator tests are not available, empirical calculations are often used, but with limitations.
Two Gulf of Mexico incidents occurred that were related to compressors not being purged properly prior to startup. BSEE issued a Safety Alert outlining the circumstances and made recommendations for prevention. Failure of a dry-gas seal in the compressor can result in plant outage and considerable revenue loss to the operating company. This paper discusses design considerations to minimize risk of failure. Compressor stations often consume 3-5% of the gas they are transporting as fuel.
Learn about the guidelines for early stages of projects and a method for evaluating the effect of inlet piping and devices on gas/liquid separator performance and useful tools to evaluate the adequacy of a proposed design. Efficient separation assumes uniform flow, but the reality of inlet geometries can invalidate this assumption, leading to separation problems and loss of separation efficiency.
Can Oversized Separators Do More Harm Than Good? Large separators are often designed to meet the requirements of higher-capacity facilities. But these vessels bring with them consequences on the operating conditions over the full life cycle of a field. Operators must take a more practical and less theoretical approach to the design and construction of three-phase separators, with an honest assessment of their separation needs. Lessons learned by the members of the SPE Separations Technology Technical Section, representing more than 250 years' experience, are presented so that the same mistakes are not repeated in the future.
Lessons learned by the members of the SPE Separations Technology Technical Section, representing more than 250 years' experience, are presented so that the same mistakes are not repeated in the future. Reliable separation is becoming an enabling technology to help develop remote location resources and more difficult applications, such as heavy oil, produced water, sand disposal, and back-produced fluids in enhanced oil recovery. In this third article of a three-part series, the results of selected gas/liquid separation case studies/sensitivities are presented to show the effects of key separator selection/sizing decision parameters, fluid properties, and operational parameters. This paper provides details of comprehensive computational-fluid-dynamics (CFD) -based studies performed to overcome the separation inefficiencies experienced in a large-scale three-phase separator. A realistic computational fluid dynamics (CFD) simulation of a field three-phase separator has been developed.
The main drivers for sizing gas scrubbers have been performance requirements, process conditions, and project specifications. An underperforming scrubber that was suffering from too much oil carry-over is described along with options for debottlenecking and improving performance. Learn how different inlet designs affect fluid dynamics and ultimately scrubber performance. "Gas Scrubber Design and Validation for Robust Separation Duty" is the title of a special session planned by the Separations Technology Technical Section. The SPE Separations Technology Technical Section (STTS) continues its study of gas scrubbing technology with a special session at the 2015 SPE Annual Technical Conference and Exhibition on 28–30 September in Houston.
