... the past four years alone [Enverus Prism, 2025]. Most of this produced water, roughly 75%, is disposed into formations shallower than the producing intervals [Smye et al., 2024]. The resulting disposal zone reservoir pressure increase from salt water disposal (SWD) can be hazardous to drilling operations...

... Abstract Storage capacity and injectivity in CCS projects depend on physical properties like porosity and permeability within injection zones, the overall volume of the zone, and whether the system allows fluid flow. In stress-sensitive reservoir rocks, increasing reservoir pressure...

In fact, we propose a triple combo IPR consisting of a set of 3 flow durations (e.g. 30-, 90- and 180-days, or 1-, 3...

... Abstract A new Diagnostic Fracture Injection Test (DFIT) procedure and analysis method was recently introduced whereby flowback data, obtained immediately after pump shut down, is analyzed for closure pressure ( p c ), reservoir pressure ( p r ) and reservoir productivity (well productivity...
