Limited studies are available for modeling gas migration in risers. Outdated and small-scale models provide insufficient reliability, and a thorough mechanistic description of the problem is still not available. A significant part of the problem concerns understanding how pressure, temperature, liquid properties, and gas-liquid dynamics effect gas expansion during migration.
This paper provides information on Computational Fluid Dynamics (CFD) simulations performed on gas injections in three static and dynamic vertical fluid columns, with and without back pressure measuring 27-ft. and 330-ft. tall with 6, 12, 19.5 in. diameter. These CFD simulations analyzed the recorded gas expansion, change in pressure and temperature, and the volume fraction of the gas throughout the riser. In addition, these simulations also analyzed the change in flow rate, velocity, and the unloading effect at the inlet and outlet.
The 330-ft. pipe simulation demonstrated explosive unloading behavior with maximum discharge velocity and flow rate of over 2.8-ft./sec. and 6617.5-gpm., while the shorter pipes demonstrated relatively slower overflow. The case with a 330-ft. pipe also recorded a rapid change in temperature close to the top. Back pressure application at the surface minimized the effects of unloading and slowed down expansion.
During the recently held 2020 SPE Annual Technical Conference and Exhibition (ATCE), winners of SPE regional student paper contests competed for the international prize in three categories: undergraduate, master's, and PhD. Winners were announced at the Student Award Ceremony held the next day. SPE coordinates 14 regional contests at the undergraduate, master's, and PhD levels. Students compete against other students in their region for the opportunity to advance to the International Student Paper Contest held during ATCE. Contestants enter an abstract of their paper and present it on the day of the competition.
As technical people working in the Montney, most of our focus has been on drilling performance, completion improvements, and overall cost reduction in all aspects. But what other trends are occurring that need to be on our radar screens? Our opening panel will be bringing many perspectives, including the funding side, the importance of ESG, consulting trends and an overview of the North American market as a whole. Exploitation design is a product of interlinked decisions on well design, completion design, well spacing and cost structure. How are Montney operators pursuing the right balance of resource recovery and profitability?
Temitope Ajayi is a full time Graduate Student/Researcher at the Craft and Hawkins Department of Petroleum Engineering, Louisiana State University, Baton Rouge USA. He was born in Lagos, Nigeria where he studied for a bachelor's degree in Petroleum Engineering at the University of Lagos. Thereafter, he earned a master's degree in Petroleum Engineering at the Petroleum Institute (now Khalifa University of Science and Technology), United Arab Emirates (UAE). He has been an active member of SPE since 2014 and has served in various capacities in the student chapters of the institutions he has attended. He has research interests in a broad range of technical topics and has worked on topics ranging from carbon dioxide storage, enhanced oil recovery, reservoir simulation and well integrity.
Decisions in E&P ventures are affected by Bias, Blindness, and Illusions (BBI) which permeate our analyses, interpretations and decisions. This one-day course examines the influence of these cognitive pitfalls and presents techniques that can be used to mitigate their impact. Bias refers to errors in thinking whereby interpretations and judgments are drawn in an illogical fashion. Blindness is the condition where we fail to see an unexpected event in plain sight. Illusions refer to misleading beliefs based on a false impression of reality. All three can lead to poor decisions regarding which work to undertake, what issues to focus on, and whether to forge ahead or walk away from a project. Strategic thinking and planning are key elements in an organisation’s journey to maximise value to shareholders, customers, and employees. Through this workshop, attendees will go through the different processes involved in strategic planning including the elements of organisational SWOT, business scenario and options development, elaboration of strategic options and communication to stakeholders. Examples are provided including corporate, business unit and department case studies. This seminar will teach participants how to identify, evaluate, and quantify risk and uncertainty in everyday oil and gas economic situations. It reviews the development of pragmatic tools, methods, and understandings for professionals that are applicable to companies of all sizes. The seminar also briefly reviews statistics, the relationship between risk and return, and hedging and future markets.
SPE, through its Energy4me programme, will present a free one-day energy education workshop for science teachers (grades 8–12). A variety of free instructional materials will be available to take back to the classroom. Educators will receive comprehensive, objective information about the scientific concepts of energy and its importance while discovering the world of oil and natural gas exploration and production. Energy4me is an energy educational public outreach programme that highlights how energy works in our everyday lives and promote information about career opportunities in petroleum engineering and the upstream professions. SPE’s Energy4me programme values the role teachers and energy professionals play in educating young people about the importance of energy.

This course covers the fundamental principles concerning how hydraulic fracturing treatments can be used to stimulate oil and gas wells. It includes discussions on how to select wells for stimulation, what controls fracture propagation, fracture width, etc., how to develop data sets, and how to calculate fracture dimensions. The course also covers information concerning fracturing fluids, propping agents, and how to design and pump successful fracturing treatments. Learn more about training courses being offered. Current and future SPE Section and Student Chapter leaders are invited to engage and share.
Thank you for attending the SPE Workshop. High rate water injectors with sustained injectivity, in unconsolidated and loosely consolidated sand reservoirs, are critical for the economic success of many projects around the globe. The objective of this workshop was to discuss and share the latest: understanding on impairment and containment mechanisms; injector conformance and performance results in the field; well completion design selection, considerations, and deployment lessons learned; well surveillance and operating best practices; and advances from the industry and academia for injectors in upstream and environmental applications. Accelerate understanding to sustain high injection, deliver fluid conformance, and maintain fluid containment for both upstream and environmental injectors.
