摘要： A variable discretization method for general multiphase flow simulation in a producing hydrocarbon reservoir. For subsurface regions for which a regular or Voronoi computational mesh is suitable, a finite difference/finite volume method (“FDM”) is used to discretize numerical solution of the differential equations governing fluid flow (101). For subsurface regions with more complex geometries, a finite element method (“FEM”) is used. The invention combines FDM and FEM in a single computational framework (102). Mathematical coupling at interfaces between different discretization regions is accomplished by decomposing individual phase velocity into an averaged component and a correction term. The averaged velocity component may be determined from pressure and averaged capillary pressure and other properties based on the discretization method employed, while the velocity correction term may be computed using a multipoint flux approximation type method, which may be reduced to two-point flux approximation for simple grid and permeability fields.

摘要： A method and system are described for generating a geologic model having material properties for a faulted subsurface region. The method and system involve parameterizing corresponding fault surfaces and solving an energy optimization equation and/or conservation law equation for the corresponding fault surfaces based on parameterized nodes on the fault surfaces to generate a displacement map. The displacement map is used to map a geologic model from the physical space to the design space, where it is populated with material properties. The resulting populated geologic model may be used for hydrocarbon operations associated with the subsurface region.

摘要： Method for transforming a discontinuous, faulted subsurface reservoir into a continuous, fault-free space where a complete geological model based on selected geological concepts can be built and updated efficiently. Faults are removed in reverse chronological order (62) to generate a pseudo-physical continuous layered model, which is populated with information according to the selected geological concept (68). The fault removal is posed as an optimal control problem where unknown rigid body transformations and relative displacements on fault surfaces are found such that deformation of the bounding horizons and within the volume near the fault surface are minimized (63). A boundary-element-method discretization in an infinite domain is used, with boundary data imposed only on fault surfaces. The data populated model may then be mapped back to the original faulted domain such that a one-to-one mapping between continuous and faulted spaces may be found to a desired tolerance (72).

摘要： The disclosure provides a method for dynamically loading a relocatable file, comprising: analyzing the relocatable file; searching for a relocation section according to the information obtained through the analysis; obtaining a relocation target address after the relocation section is found and calculating an address to be relocated and a skipping distance; determining whether the skipping distance exceeds a range of a short skipping, and if the skipping distance does not exceed the range of the short skipping, then writing the relocation target address into the address to be relocated to perform relocation loading; if the skipping distance exceeds the range of the short skipping, then adding a veneer code segment and making the skipping whose distance exceeds the range of the short skipping indirectly skip to the relocation target address to perform relocation loading. Accordingly, the disclosure provides a device for dynamically loading a relocatable file, comprising: an analyzing module, a calculating module, a searching module, a determining module, and a relocation dynamic loading module. With the solution, dynamically loading a relocatable file can be realized when the calling distance of a function exceeds the range of the short skipping.

摘要： A method and apparatus for generating a simulation grid for a reservoir model based on a geological model comprising horizons, constraints and multiple geological grid cells. A pre-image is generated corresponding to the geological grid cells, the pre-image comprising a surface and the modeling constraints being mapped onto the surface. A constrained two-dimensional grid is generated on the pre-image, the two-dimensional grid comprising multiple grid cells. Simulation layer boundaries are selected from the geological model and the constrained two-dimensional grid is projected onto the simulation layer boundaries. Prismatic cells are then generated to form the three-dimensional simulation grid. The method of generating a grid as herein described may be incorporated in existing reservoir simulators to improve their accuracy.
