摘要： Methods for injecting a fluid into a subsurface formation are provided. Each of the methods includes the obtaining data, including formation parameters and operational variables, related to an injection well. A regime of operation for the injection well is determined. The regime of operation is determined using a heuristic model. In one aspect, one or more operational variables, including completion design, reservoir development procedures, and/or injection procedures, is designed based at least in part on the determined regime of operation. Water or other fluid may then be injected into the subsurface formation. The step of determining the regime of operation for the injection well may use a full physics computational simulation to construct a mathematical model that can estimate the operating regime for the water injection well. Alternatively or in addition, field data may be used.

摘要： A method of predicting earth stresses in response to changes in a hydrocarbon-bearing reservoir within a geomechanical system includes establishing physical boundaries for the geomechanical system, acquiring logging data from wells drilled, and acquiring seismic data for one or more rock layers. The well and seismic data are automatically converted into a three-dimensional digital representation of one or more rock layers within the geomechanical system, thereby creating data points defining a three-dimensional geological structure. The method also includes (a) applying the data points from the geological structure to derive a finite element-based geomechanical model, and (b) initializing a geostatic condition in the geomechanical model, and then running a geomechanics simulation in order to determine changes in earth stresses associated with changes in pore pressure or other reservoir characteristics within the one or more rock layers.
