Integrated workflow for feasibility study of Deblais Reinject based on three-dimensional geomechanical analysis

摘要

Methods and systems are presented in this specification for a feasibility study of a spoil reinjection process (CRI) based on three-dimensional (3-D) geomechanical analysis. The location of an injection well for the CRI and a true vertical depth (RST) interval of an injection section along a trajectory of the injection well can first be determined. Then we can calculate a window of values for an injection pressure for hydraulic fracturing carried out in connection with the injection well. We can analyze the reactivation of faults due to hydraulic fracturing, and we can calculate a fracture volume produced by hydraulic fracturing. The IRC can be performed for the fracture volume at the determined injection well location for the RST interval, taking into account the injection pressure window and the fault reactivation analysis.
