Abstract: A free-space well connection method of determining parameters for modeling a reservoir is disclosed. The method is conducted by a computer system (100) having a processor (110) and non-transitory memory (120) that stores data including instructions to be executed by the processor (110), the processor (110) executing a modeling module (102) stored in the memory (120), the modeling module (102) having data representing a grid with a well-cell (202) and at least one link-cell (204), each of the at least one link-cell (204i) having a common face (Γi) with the well-cell (202), the well-cell (202) and the at least one link-cell (204) being a local cell array. The method comprises steps of modeling, by the modeling module (102), the local cell array as having an infinite outer boundary by modeling the grid as an infinite space around the local cell array for determination of parameters for the well-cell (202) and determining, by the modeling module (102), one or more of a well connection transmissibility factor (Tw) and at least one inter-cell transmissibility multiplier (Mi).

Abstract: The present invention relates to a method of providing a geologic model representing geologic features based on geologic measurement dataset constituted by a number of data points sampled in a chosen region. The method includes the following steps: a) receiving at least one user selected control point (1) representing a geological feature in the measurement data set, b) providing an initial guide surface (2) with a predetermined shape, the control point (1) being positioned in said initial guide surface, c) comparing said initial guide surface shape with the sampled data points (4) for detecting measurement data points being similar to the measurement data of said control point (1), providing a vertical difference value representing the vertical difference between the depth of the guide surface and the depth of said corresponding data points for each compared data point in said set, d) from a selected set of said difference values, generating a new guide surface (5) corresponding to the control and data points.

Abstract: Method of providing a geologic model (1′) representing a geologic feature based on geologic measurement data, such as seismic or electromagnetic data. The method comprises the following steps determining an initial model estimate. Further the method comprises, by means of a metric function, comparing features of a plurality of candidate traces (19) with known features of a model control point (3). For the candidate traces (19) where the metric function returns a similarity value above a similarity metric threshold, a model guide point (9) is arranged on the candidate trace (19) in question. The geologic model (1, 1′) is adjusted towards or onto such model guide points (9).
