Technology Focus: Well Integrity (January 2026)

_ Two critical facets of the discipline of well control and wellbore integrity—decarbonization and groundbreaking automation of essential processes—are highlighted in the three primary paper selections presented at SPE and SPE-affiliated conferences during the past year. These authors advance studies dedicated to heightening safety and embracing the energy transition, two goals that must be interwoven as the industry enters the second quarter of the century. In paper SPE 221116, the authors describe a methodology for analyzing blowout-preventer (BOP) pressure charts that leverages computer vision to decode image captures of data in conjunction with a BOP-inspection application. Their findings indicate that an average of 90 minutes can be saved per test while the accuracy of readings is simultaneously improved. Additionally, the operator deploying the technology has reported a 300% return on investment. Plugged and abandoned (P&A) wells are already playing a crucial role in CO2-storage projects, but they pose special challenges because of the potential for corrosion and decreased casing thickness once they are exposed to CO2. The authors of paper SPE 222449 present a modeling framework that provides a quantitative, risk-based assessment of the long-term integrity of P&A wells. The framework includes three newly developed modules (centered on geochemical, geomechanical, and corrosion concerns) customized for CO2 storage. The authors of paper SPE 225550 adopt a broad scope in addressing the discipline’s ability to accommodate and enhance the energy transition. The paper summarizes their findings from laboratory experiments conducted in recent years on wellbore integrity for geothermal projects, geological CO2 storage, and hydrogen storage. A wide range of concerns, approaches, and options are reviewed, from existing salt-cavern-storage projects to methods of drilling new wells that better accord with net-zero goals.
