Saudi Aramco studied such algorithms to produce images simulating the flow inside a pipe’s cross section, possibly reducing the need for separator-based multiphase flowmeters. A former technical manager with Petrobras discusses the development of the company’s flow assurance philosophies and strategies. Looped lines are used to reduce pressure drop and increase flow capacity, but information on the flow behavior or predictive methods are not available for these systems. Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.
Natural-gas-infrastructure reliability is critical for the energy sector. When capitalizing on old pipelines to transport natural gas, operators run the risk of partial blockage. In this study, the authors develop a multirate test method to detect partial blockage in a gas pipeline. This paper presents the results of tests conducted to design a fast-breaking gelled fluid for a debris-removal operation in a long, large-diameter subsea pipeline in the Asia Pacific region.
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 room for error and cost overruns just got a lot smaller with the escalating need to make operations more efficient and leaner with fewer resources and investors continuing to prioritize ESG alongside profitability.
P-68 is Petrobras’ fourth FPSO to begin operations this year following the startups of P-67 at the Lula field and P-76 and P-77 at the Buzios field. Hydrocarbon processing and treating systems often require large and elaborate surface facilities. When operating in challenging locations, such as deep water or the Arctic, these systems can be expensive. Petrobras and Shell have brought online the Lula field’s seventh FPSO as the firms continue to ramp up production from the pre-salt Santos Basin. The Turritella FPSO (Figure 1 above) is the deepest floating production system in the world and presented many challenges to successful execution of the surface host facilities.
The effectiveness of delivering information about a new energy project to community stakeholders varies based on the method used; how a message is framed can affect individual opinions. Models were developed for these wells for future water-production prediction and a spatial analysis was also conducted. This article explores the outlook for the global market and gives insight into technology trends and the regions that hold the biggest opportunities for water treatment.
In the complete paper, the authors revisit fundamental concepts of reservoir simulation in unconventional reservoirs and summarize several examples that form part of an archive of lessons learned. New report offers guidelines for pressure pumpers of the future. A 3-year study of air quality, soils, groundwater, and waterways found few to no effects as a result of hydraulic fracturing operations in Surat Basin coal seam formations. Not everybody suffers when US oil producers slash production. Among the beneficiaries could be US gas producers who will benefit because less oil production will mean a lot less gas on the US market.
A new idea from Equinor calls for autonomous submarines to transport CO2 from the surface to the seabed. The Norwegian operator says the shuttles could also carry oil and water for injection. Phase 1 is expected to be operational in 2024. For the offshore sector, the collapse in oil demand and prices came just as the market was beginning to look up. Now many companies are focused on survival.
Carbon dioxide (CO2) waterless fracturing uses liquid CO2 to replace water as the fracturing fluid in reservoir stimulation. The continuity and reliability of the blender are key factors determining performance of the operation. The complete paper discusses an advanced matrix-stimulation work flow that brings reliability and flexibility to the acidizing of tight carbonate water injectors and has delivered injectivity improvements tight carbonate onshore reservoirs in the Middle East. The complete paper discusses a method of stimulating deep, high-temperature offshore wells by combining an efficient single-phase retarded acid (SPRA) system and an engineered, degradable, large-sized particulate and fiber-laden diverter (LPFD). Several well-stimulation products and techniques have been seen to benefit well productivity from recent field trials and implementations in carbonate reservoirs, including simpler acid fluid systems, integrated work flows, and coiled-tubing bottomhole assemblies.
An investigator from the US National Energy Technology Laboratory examines the role remotely operated vehicles played in flow rate estimation from the Macondo well. Various incidents that took place between Transocean, the owner of Deepwater Horizon, and BP, the company that leased the rig for use at Macondo, illustrate the gap between work-as-imagined in the drilling program and work-as-done by the well operations crew. The presence of slug flow in the riser of the sunken Deepwater Horizon could make a significant difference in financial penalties for BP in the wake of the Macondo incident, an expert said. Several different factors contributed to the Macondo accident, according to an analysis by the CSB. The understanding of decision-making processes is critical in ensuring project success and safety.
The oil and gas industry must learn to engage with local citizens better if it is to build upon its social license to operate. A joint PFC/HSE luncheon during ATCE addressed this topic. Energy development projects that affect local communities frequently face opposition. This article describes an approach to dealing with local communities that has proved effective. Expectations have continued to rise over recent years regarding how oil and gas projects and facilities analyze, manage, and communicate about their social and environmental performance.
