Pore and Fracture Pressure Risks, Technologies, and Operating Strategies

Tuesday, 2 May
Technical / Poster Session
Accurate characterization of pressure and stress in the subsurface is essential for safe and efficient well design and operations. The exchange of non-proprietary ideas and open discussions facilitate common understanding amongst PPFG practitioners as we attempt to safely execute operations without damage to human life and the environment. This session is aimed at technical professionals who create and/or use pore pressure and fracture gradient (PPFG) predictions. PPFG predictions are critical to managing the uncertainties and risks in various business stages, including drilling, well construction, intervention, and abandonment operations. Presentations will focus on cross-discipline integration and uncertainty management in difficult geologic and drilling environments. Topical areas will include incorporation of geomechanics and complex stress environments, impacts of clay diagenesis, geologic plumbing, and data science applications to drilling parameters for real-time guidance during operations.
