Abstract

Heterogeneity of a geological volume of interest is assessed. The heterogeneity of the geological volume of interest may refer to the quality of variation in rock properties within location in the geological volume of interest. An accurate and / or precise assessment of the heterogeneity of the geological volume of interest may enhance modeling, formation evaluation, and / or reservoir simulation of the geological volume of interest, which may in turn enhance production from the geological volume of interest. As described herein a stochastic, process-based modeling approach to modeling the geological volume of interest, along with a determination of dynamic heterogeneity may be leveraged to quantify the heterogeneity of the geological volume of interest.

Description

technical field [0001] The present disclosure relates to assessing heterogeneity of a geological volume of interest using a stochastically generated process-based earth model and determination of dynamic heterogeneity made from the earth model. Background technique [0002] Historically, reservoir systems have been characterized using both deterministic and stochastic methods. The model includes a single use case or multiple realizations that integrate geological data, engineering data, and human expertise into what is believed to be the best subsurface representation of the reservoir, and correlates uncertainties with available data. Realizing. However, in exploration and appraisal settings, drilling control is sparse and subsurface imaging of the architecture using seismic data is often problematic. Model inaccuracies are thus multifaceted, including inaccuracies in interpreters and modelers due to information gaps and inexperience. Results anchored on a given scenario ...
