摘要： System and method for implementing a reservoir simulation system are described. One embodiment is a computer-implemented method of coarsening a fine grid including a plurality of fine gridblocks, the fine grid representing a geological model having at least one discontinuity therein. The method comprises grouping a number of fine gridblocks together to form coarse gridblocks, wherein at least one of the coarse gridblocks is a nonstandard-shaped gridblock; and calculating a transmissibility for each pair of adjacent coarse gridblocks in which at least one gridblock of the coarse gridblock pair is a nonstandard-shaped gridblock. The calculating comprises calculating a transmissibility for each pair of adjacent fine gridblocks; mapping each of the fine gridblock pairs to a coarse gridblock pair; and for each gridblock pair, summing the transmissiblities of the fine gridblock pairs mapped thereto.

摘要： A suite of processes and tools for preprocessing data prior to seismic interpretation including: voxel connectivity mapping, seismic response reduction, voxel suppression and voxel density. Voxel connectivity is used to assist with removing insignificant data. Seismic response reduction is used to reduce the seismic response of a given reflector to a lobe, such as a main lobe. Voxel suppression assists with highlighting and enhancing lithologic boundaries to aid in human and computer-aided interpretation. Voxel density scores the local significance of data trends within a volume, such as a 3-D seismic volume, to assist with the enhancement of these trends.

摘要： Distinct paths (40), e.g., locally optimal, are determined in a heterogeneous velocity field (32) between a source object and a target object (33) using gradients (35) of a two-way total arrival time field (34). The foregoing technique may be used to assess hydrocarbon reservoir connectivity.

摘要： Methods for analyzing the connected quality of a hydrocarbon reservoir are disclosed. A model of a portion of the reservoir is divided into cells, each cell having a volume and some attributes, and wherein a speed function is assigned to a portion of the cells. A reference cell is chosen. A connectivity between cells in the reservoir is determined by solving an Eikonal equation that describes the travel time propagation, said propagating front progressing outward from a reference cell until an ending condition is met, said Eikonal equation being solved by a fast marching method with propagation velocity as a function of spatial position being provided by the speed function. Regions of the reservoir are characterized by their connective quality to the reference cell using the connectivity.

摘要： A method is disclosed for determining the connectivity architecture of a hydrocarbon reservoir in terms of locally optimal paths between selected source points, e.g. wells. In one embodiment of the invention, a fast-marching method (133) is used to compute the distance field (or the time of arrival field) from N selected source points in a heterogeneous media, i.e. in a non-uniform velocity field. This is done by propagating N labeled (132) fronts simultaneously from N objects. Then, a method (134) is disclosed for detecting Voronoi curves or Voronoi surfaces, where fronts of differing labels meet each other. Then, saddle points are found on the Voronoi curves or surfaces (135), and each saddle point is used to determine a locally optimal path (136) between a pair of equidistant (from the saddle point), closest (to the saddle point) source points.

摘要： A method of determining a migration pathway of a subterranean fluid through a geological volume is provided. The starting object is located within the geological volume. The starting object defines an initial fluid boundary. Data points are distributed through the geological volume. The data points are associated with values of one or more geological attributes. The method includes the steps of: defining an expression which determines a change in position of the fluid boundary at the data points over an iteration based on the values of the one or more attributes; and applying the expression at the data points for successive iterations to evolve the fluid boundary over the successive iterations. The migration pathway of the subterranean fluid through the geological volume can then be determined from the evolution of the fluid boundary.

摘要： Various implementations described herein are directed to a method for assessing risks of compartmentalization. In one implementation, the method may include receiving seismic data for a formation of interest; identifying areas in the formation having a dip angle greater than about 30 degrees; performing a plurality of downhole fluid analysis (DFA) within a wellbore around the formation having the dip angle greater than about 30 degrees to identify areas experiencing mass density inversion; and determining the areas experiencing mass density inversion by DFA as having one or more risks of compartmentalization.
