Ten years ago, news reports frequently cited peak oil as a looming problem facing our world. Technology and innovation has since been developed that allows us to tap into rocks that were previously deemed impossible to extract oil from, reversing this trend. The Western Canadian Sedimentary Basin has been a leader in this movement with entrepreneurs using new technology to develop our resources in a safe and reliable way.

This course will provide a general overview of current and emerging heavy oil recovery methods with emphasis on field experiences in Alberta and steam assisted gravity drainage (SAGD). Participants will learn about the concepts, field development, reservoir performances, applicability, challenges, and issues of the various in-situ recovery methods. Discussions in this session focus on carbonate reservoir recovery processes and mechanisms, from field experiences to laboratory observations. Topics include thermal casing and cement, Sand control, well intervention, and wellbore simulations. This session addresses the fundamentals and tools for predicting benefits of and usage of solvent for enhanced recovery.Â Topics include both water-soluble solvents and the more traditional hydrocarbon solventsâ€™ viscosity, relative permeability, heat and mass transfer, sampling, and reservoir performance prediction.
A new licensing round will open up 136 blocks in the Arctic Barents Sea. 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. The Offshore Technology Conference was cancelled for the first time ever due to the COVID-19 pandemic. But the flow of ideas continues.
This paper presents a state-of-the-art review of scale-inhibitor-analysis techniques and describes how these techniques can be used to provide cost-effective scale management. Calcium sulfate (CaSO4) in the form of gypsum and anhydrite is one of the more prevalent evaporite minerals typically found in the carbonate rocks of the western Canadian sedimentary basin (WCSB).
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. 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. This article discusses how various market segments, regions, and companies are faring in “the new reality.” This paper presents a fatigue-prediction methodology designed to extend the life of unbonded flexible risers and improve the accuracy of floating production, storage, and offloading vessel response analysis.
The complete paper discusses the importance of adequate preparation and the approaches used to overcome challenges of EOR operations, including handling back-produced polymer. 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. Researchers use novel methodology to measure the thermo-electric properties of native crude. Business Development VP Kirstie Boyle joins The SPE Podcast to talk startups. Recently part of a $4.5-million funding round, Kirstie shares what makes Interface Fluidics flow.
This comprehensive course is an introduction or refresher for the techniques of evaluating Canadian oil and gas properties, but the techniques used in this course also apply to oil and gas properties elsewhere in the world. There is ample opportunity to work problems in class. By the end of this course, participants will be able to evaluate an oil and gas property and interpret evaluations done by others. The material in the course is very practical, with many tips and insights in evaluating wells, groups of wells, properties and companies. This course is for engineers, geologists, geophysicists, land negotiators, accountants, technologists, and anyone who wants to understand the process and results of evaluating Canadian oil and gas properties.
The development of unconventional basins across North America for the past decade initially caused some in the industry to wonder if challenges found in unconventional basins would require new chemistries and technologies. As the basins have been produced and water chemistries evaluated and treated, it has become clear that established scale inhibitor chemistries and methodologies are suitable to treat unconventional scaling scenarios. However, the number of applicable chemistries can be limited as some of the most common scale inhibitor chemistries have been found lacking in iron tolerance. The biggest lesson learned over the course of the past decade has been to not underestimate the role that iron can play as spoiler not only in performance of scale inhibitor chemistries, but also in test methodologies and monitoring techniques. While the need to account for iron in conventional programs has not been taken for granted, the amount of iron produced in unconventional production basins has led to a re-evaluation of just how severely iron in solution can impact scale programs from product testing and selection all the way through to program monitoring.
This paper highlights the brine chemistries in major North American unconventional basins, especially regarding iron. Test methods and results from dynamic scale loop and anaerobic static bottle testing will be highlighted as well as the limitations of using field brines in product evaluations. Field observations will be discussed to support the importance of proper product selection as well as monitoring techniques.
This subject has implications for the industry as unconventional basins across North America continue to search for program improvements to drive reductions in total operational costs. Additionally, as unconventional basins are developed outside of North America, the lessons learned can be applied to efficiently develop best in class scale inhibitor programs. As appreciation for the impact of high levels of iron on scale inhibitor performance continues to evolve, there is a possibility that a smaller amount of iron tolerant scale inhibitors will limit the treatment options available in unconventional production basins.
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 injecitons. The Offshore Technology Conference was cancelled for the first time ever due to the COVID-19 pandemic. But the flow of ideas continues. As proof, this curated summary of technical papers highlights unique concepts that might someday reduce the offshore sector’s heavy cost burdens.
