For offshore wells, particularly deepwater completions in depleted reservoirs, the challenges are significantly greater than in virgin reservoirs because reservoir pressure depletion narrows the operating window. This leads to, and increases, the risk of formation damage, losses, well control events, and completion failure. Other issues are dealing with fluid loss pills, assessing risk from mud losses or poor cement behind pipe. Successful completion of depleted reservoirs requires a more holistic approach to its design that takes the whole well history from the start of drilling the reservoir into account. In this SPE Live, the panelists will discuss the critical challenges, technologies available to address these challenges, and any gaps. They will also discuss/evaluate best practices for successfully completing depleted reservoirs.

Technical sections offer SPE members a powerful way to learn, share, connect and grow. From webinars and awards to student programs and global networking, these communities provide opportunities to build technical expertise and lasting professional relationships. Discover why they may be one of SPE’s most valuable member benefits.

This SPE Live will explore whether and how geomechanics plays a critical role in influencing and improving how our industry understands, develops, and manages subsurface resources. Key discussion points will highlight the value of geomechanics, particularly when it is not treated in isolation but integrated with geology, geophysics, petrophysics, reservoir engineering, drilling, completions, and production to build a more comprehensive understanding of formation behavior.We invite practitioners, researchers, users, and service providers to discuss challenging issues surrounding the importance of geomechanics and explore how the exchange of knowledge and best practices can strengthen the profession.

Hydraulic fracturing revolutionized unconventional oil and gas — and the same stimulation science is now being adapted to unlock next-generation geothermal energy. Enhanced Geothermal Systems (EGS) and Superhot Rock (SHR) concepts borrow heavily from decades of shale completions know-how, but operating at temperatures exceeding 300°C, in crystalline basement rock, introduces entirely new engineering challenges: engineering a reservoir volume, proppant and fluid stability, wellbore integrity, reservoir management under extreme thermal and mechanical stress and more that we will find out through time.

In this SPE Live, we will dive into the synergistic approach of subsurface engineering and hydraulic fracturing from the oil and gas world into the geothermal realm. The conversation will explore where oilfield technology has direct transfer capabilities, where it must be reinvented, and what this convergence really means for the future of dispatchable geothermal power.

The Reserves Education Subcommittee (RES) within the Oil and Gas Reserves Committee (OGRC) is a global group of subject-matter experts advancing PRMS education. The RES were recently mandated by the OGRC to update, design, and prepare a reserves education framework in modular presentations. The initiative resulted in the development of thirteen (13) modular presentations encompassing core PRMS principles, reserves classification, maturity distinctions, evaluation methodologies, commerciality/economic criteria, and common areas of misinterpretation observed in industry. The modules form the “PRMS Training Master Slides” and are to be taught by OGRC approved instructors and offer a practical and interactive approach as a third trilateral source on PRMS knowledge and education supported by OGRC.

The “PRMS Training Master Slides” are standardized, committee-endorsed training for global dissemination across operators, consultants, educators, and regulators. It is anticipated they will perpetually improve global alignment on reserves estimation and classification, provide a clearer differentiation between resources and reserves, and finally a more consistent understanding of commercial maturity thresholds. These modular presentations will complement the much-needed training gap identified by OGRC.
