Embodiment Construction

[0016] figure 1 A system 10 configured to estimate the geological structure of a geological body of interest is illustrated. The geologic structure of the geologic volume of interest is estimated by generating and / or selecting one or more numerical simulation models of the geologic volume of interest representing properties of the geologic volume of interest as a function of position within the geologic volume of interest. Estimation of the geological structure of the geologic body of interest can be achieved during reservoir exploration and / or development. In one embodiment, system 10 includes electronic storage 12, user interface 14, one or more information resources 16, one or more processors 18, and / or other components.

[0017] In one embodiment, electronic storage 12 comprises electronic storage media that electronically stores information. The electronic storage media of electronic storage 12 may include system memory that is integrally equipped (i.e., substantially n...

Abstract

The geological architecture of a geologic volume of interest is estimated through the generation and / or selection of one or more numerical analog models of the geologic volume of interest that represent characteristics of the geologic volume of interest as a function of position within the geologic volume of interest. The estimation of geological architecture of the geologic volume of interest may be implemented in reservoir exploration and / or development.

Description

technical field [0001] The present invention relates to estimating the geological structure of a geological body of interest by generating and / or analyzing a set of numerical simulation models. Background technique [0002] In the field of geological exploration, structural uncertainty models are needed for reservoir exploration and development. Reservoir structure parameters include reservoir property distribution, strike, stacking pattern, and geometry of geological bodies. These parameters often have a critical control over the response of the reservoir to the production plan. Often, locally obedient data (eg, well logs, cores, seismic data, etc.) are insufficient to reliably infer structural parameters and their associated uncertainties. Broad, preliminary uncertainty models can be applied, but they are highly subjective, ignore important expertise, and are of limited use in quantitative judgments. Contents of the invention [0003] One aspect of the invention relat...
