摘要： A system and method for summarizing data corresponding to properties of interest on an unstructured grid that includes active cells and inactive cells on an output surface. An exemplary method comprises identifying an aggregation direction through a region of interest of the unstructured grid and identifying at least one active cell along the aggregation direction. The exemplary method comprises assigning an aggregated value for the at least one property of interest to a face of the output surface on a line along the aggregation direction based at least in part on the data corresponding to the at least one property of interest for the at least one active cell. The exemplary method further comprises filling the at least one data hole by identifying at least one face associated with an inactive cell on the line along the aggregation direction and assigning it an aggregated value.

摘要： In solving linear systems of billions of equations resulting from reservoir simulator pressure equations for giant reservoirs organized into fine-grid models, a multi-level methodology acquires a fast and coarser grid solution to be used as a more accurate initial estimate for the fine grid problem. Solver iterations performed on the coarser grid in reduced processing time generate a better initial estimate, resulting in fewer of the more expensive iterations at the fine-grid level.

摘要： Disclosed is a method of modelling a subsurface volume. History data for one or more parameters over a first period of time is obtained. The first period of time comprises a plurality of schedule periods, each schedule period having associated with it a sampled value of the considered parameter at the corresponding time. A merge error value is attributed to plural pairs of consecutive schedule periods, the merge error value representing a magnitude of the error in a merged value of each parameter over the duration corresponding to a pair of schedule periods being considered, relative to the sampled values for said pair of schedule periods being considered. The pair of schedule periods which have the smallest error value attributed thereto is merged, and the merged schedule period has attributed to it, the corresponding merged value of the corresponding parameter. The error value calculation and merger steps are repeated so as to reduce the total number of schedule periods.

摘要： A method for editing a volume-based model imaging geological structures. An initial volume-based model comprising a volumetric mesh and updated geological data defined within a region of the model is received. The volume-based model is decomposed by converting the volumetric mesh into surface meshes linked by stratigraphic fibers to generate a surface-based model. The defined region of the surface-based model is edited by editing positions of control nodes of the surface meshes along the stratigraphic fibers in the defined region of the model so as to fit the updated geological data. The plurality of stratigraphic fibers are updated based on the edited positions of the control nodes so as to fit the updated geological data. The edited surface-based model is meshed to generate an updated volume-based model comprising a volumetric mesh defined by the edited positions of the control nodes. The updated volume-based model is stored and/or displayed.

摘要： There is provided a system and method for automatically identifying potential compartments of a reservoir based on the reservoirs geological structure. A method of identifying compartments of a reservoir structure includes obtaining structural data corresponding to a geological structure of a reservoir. The method also includes generating a topological net based on the structural data, the topological net comprising critical points and poly segments connecting the critical points. The method also includes identifying potential compartments of the reservoir structure based on the topological net. The method also includes identifying spill or break-over relationships among the potential compartments based on the topological net.

摘要： A method of generating a model of a turbidity current in a fluid is disclosed. A first flow layer in the turbidity current is defined. The method successively defines at least one more flow layer in the turbidity current. Each successive flow layer includes the previously defined flow layer. A set of depth-averaged flow variables for each flow layer is defined. A model is developed that describes the turbidity current. The model uses fluid flow equations and the set of depth-averaged flow variables for each flow layer to predict fluid flow in each flow layer. The model is then output.
