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.
In the complete paper, the authors reduce nonuniqueness and ensure physically feasible results in multiwell deconvolution by incorporating constraints and knowledge to methodology already established in the literature. 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. In the complete paper, a novel hybrid approach is presented in which a physics-based nonlocal modeling framework is coupled with data-driven clustering techniques to provide a fast and accurate multiscale modeling of compartmentalized reservoirs. Machine learning enables fast, cost-effective, and accurate methane emissions detection in remote areas. This paper describes a smart-tracer-portfolio testing and design solution for multistage hydraulic fracturing that will, write the authors, enable operators to reduce operating cost significantly and optimize production in shale wells.
Will Blockchain Become the New Operational Backbone in Energy? Energy companies are looking to distributed ledger technology—otherwise known as blockchain—to help navigate the complex transactional systems that make up their operations. What is blockchain, and what makes it valuable to our industry? Statoil’s integrated operations center on the Norwegian continental shelf is one of several initiatives operators and service companies have set in motion to improve condition monitoring and maximize production on their assets. The company’s 31 licenses highlight a record-high total awarded during the latest APA round, which is aimed at developing mature areas of the NCS.
Pemex and Talos Energy have 120 days to decide how to share a massive offshore field that both companies claim they should operate. Failure to come to terms means the government will decide the matter. Barbara Burger says the key interest areas for the supermajor’s portfolio of startup investments remains unchanged despite a new industry downturn. However, the environment is tighter and the way in which deals are made has already seen notable change. Have Oil Sands Producers Found an On-Off Switch for Their Wells?
If you have used the random forest algorithm, then you already have used the Ensemble Machine Learning (EML) method, probably without realizing it. This article will explain, in very simple terms, the principle behind this relatively new ML paradigm. Can Data Science Help Solve One of the Oil Industry’s Thorniest Problems? Water-in-oil emulsions cost millions in maintenance, reduce oil recovery, and create excess carbon. These economic and environmental burdens may finally be resolved. The evaluation of waterfloods often is focused on issues at the well level.
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.
A new licensing round will open up 136 blocks in the Arctic Barents Sea. Because the greenfield can use existing infrastructure, the Norwegian operator says it will count as a low-carbon development. The first of three major unconventional developments in Saudi Arabia has been given the green light. The project will underpin the country's goal to become a top gas exporter by 2030. The Italian oil and gas company has found its second big well offshore Mexico and is setting its sights on several more in the near future.
A new licensing round will open up 136 blocks in the Arctic Barents Sea. The complete paper describes the overall project execution of the Aasta Hansteen field development on the Norwegian Continental Shelf (NCS) north of the Arctic Circle. It is the deepest field yet developed on the NCS in 1300 m of water. Many forms of remote sensing imagery can be used, along with data sets and the resultant products, to improve the efficiency and safety of upstream oil and gas operations on the North Slope of Alaska. The $5.6-billion deal includes the Prudhoe Bay field and the Trans Alaska Pipeline and vaults Hilcorp to be the second-largest Alaska producer and reserves holder, behind only ConocoPhillips.
A new licensing round will open up 136 blocks in the Arctic Barents Sea. Country had hoped to boost oil output and bring in much-needed revenues. Two discoveries offshore Mexico add to April’s finding in the Norwegian Sea. Oil companies large and small have pulled out the stops to stay on solid ground. The move to combine forces comes amid the fastest contraction in drilling activity the US shale sector has ever seen while Gyrodata will retain its international business.
After a career in risk management in the oil and gas industry, 1997 was a turning point in which she took a sabbatical to volunteer in post-Soviet Armenia with a grassroots Franco-Armenian aid agency called Solidarité Protestante France-Armenie. Her return to Schlumberger, where she had previously been a risk manager for the seismic and wireline businesses, took her formally into a field in which she had long had an informal interest – the impact of business on society. For six years, starting in 1998, she lived in New York and held management responsibilities for the first global community outreach program – Schlumberger Excellence in Educational Development (SEED) - leading implementation, development and promotion, internal and external communications, development of peer relationships, and incubation support of other outreach activities. In 2004 she returned to Paris to take on a double role. One of her roles was transforming the Schlumberger Foundation into a strategic philanthropic vehicle.
