摘要： A method for performing a modified two point flux approximation scheme is disclosed. The method includes: obtaining a first pressure value for a first neighbor cell and a second pressure value for a second neighbor cell, where the first neighbor cell has a first value of a reservoir property and the second neighbor cell as a second value of the reservoir property; determining a first weight using the first pressure value and a second weight using the second pressure value; calculating a third value of the reservoir property as a weighted average of the first value and the second value; and applying the third value to the first neighbor cell.

摘要： A method for performing a field operation of a field. The method includes obtaining historical parameter values of a runtime parameter and historical core datasets, where the historical parameter values and the historical core datasets are used for a first simulation of the field, and where each historical parameter value results in a simulation convergence during the first simulation, generating a machine learning model based at least on the historical core datasets and the historical parameter values, obtaining, during a second simulation of the field, a current core dataset, generating, using the machine learning model and based on the current core dataset, a predicted parameter value of the runtime parameter for achieving the simulation convergence during the second simulation, and completing, using at least the predicted parameter value, the second simulation to generate a modeling result of the field.

摘要： Using a CPU and at least one GPU to simulate geomechanical reservoir deformation due to a change in force on the reservoir is presented. An example method includes obtaining a stiffness matrix representing a finite element mesh for a grid of the reservoir, obtaining a load vector representing the change in force, determining a displacement vector representing the deformation of the reservoir, by computing, as a setup process apart from a conjugate gradient solver iteration, and by the CPU and the at least one GPU, at least a portion of a deflation operator and iterating, by the CPU and the at least one GPU, a conjugate gradient solver applied to a system of linear equations defined by at least the deflation operator, the stiffness matrix, the load vector, and the displacement vector, such that a deflated solution corresponding to the displacement vector is produced.
