Abstract: An example modeling process of pore pressure and injected waste distribution profile may include several steps. A hydrodynamic flow simulation model may be built according to the geometry and/or physical properties of the subsurface formation. A fluid distribution and pore pressure profile in the subsurface may be affected by the geometry and orientation of hydraulic fractures created as a result of drill cuttings subsurface injection (cuttings re-injection or CRI). A fracture profile may be generated using a hydraulic fracturing simulation and may then be embedded into the hydrodynamic simulation model. In some examples, the nature of injected fluids in the same formation and through the same well, fracture, and/or perforation interval may lead to modification of the subsurface formation properties, and this may be accounted for in the simulation.
