摘要： Methods for generating a surrogate model for subsurface analysis may include identifying input parameters for the subsurface analysis, and selecting a range of values for the identified parameters. The methods also include selecting a design of experiments method for filling sampling points within the ranges of values for the identified input parameters. The design of experiments method may be a classical method or a space-filling technique. The methods also include filling sampling points within the ranges of values for the identified input parameters. The sampling points are filled based on the design of experiments method selected. The methods further include acquiring output values for each of the selected sampling points, and constructing a surrogate model based upon the output values for at least some of the selected sampling points. The surrogate model is a mathematical equation that represents a simplified model for predicting solutions to complex reservoir engineering problems.

摘要： Methods of predicting earth stresses in response to pore pressure changes in a hydrocarbon-bearing reservoir within a geomechanical system, include establishing physical boundaries for the geomechanical system and acquiring reservoir characteristics. Geomechanical simulations simulate the effects of changes in reservoir characteristics on stress in rock formations within the physical boundaries to determine the rock formation strength at selected nodes in the reservoir. The strength of the rock formations at the nodes is represented by an effective strain (ε eff ), which includes a compaction strain (ε c ) and out-of-plane shear strains (Υ1-3, Y2-3) at a nodal point. The methods further include determining an effective strain criteria (ε eff cr ) from a history of well failures in the physical boundaries. The effective strain (ε eff cr ) at a selected nodal point is compared with the effective strain criteria (ε eff cr ) to determine if the effective strain (ε eff ) exceeds the effective strain criteria (ε eff cr ).

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.
