METHOD OF GENERATING NUMERICAL PSEUDOCORES USING BOREHOLE IMAGES, DIGITAL ROCK SAMPLES, AND MULTI-POINT STATISTICS Russian patent published in 2012 - IPC G01V8/00 

FIELD: physics.

SUBSTANCE: methods of creating a numerical pseudocore model involving: a) obtaining logging data from a reservoir having depth-defined intervals of the reservoir, and processing the logging data into at least one interpretable borehole image data having unidentified borehole image data; b) examining one of the interpretable borehole image data, other processed logging data or both to generate the unidentified borehole image data, processing the generated unidentified borehole image data into the interpretable borehole image data to generate warped fullbore image data; c) collecting one of a core from the reservoir, the logging data or both and generating a digital core data from one of the collected core, the logging data or both such that generated digital core data represents features or structures of one or more depth-defined interval of the reservoir; and d) processing generated digital core data, interpretable borehole image data or the logging data to generate realisations of the numerical pseudocore model.

EFFECT: creation of three-dimensional numerical cores from computed X-ray tomography data and formation micro-image logs, and performing flow modelling in these numerical cores to understand fluid-flow paths and recovery factors in the selected reservoir.
