The invention is directed to methods for improving the recovery of oil from subterranean geological formations, such as unconventional reservoirs. The invention is also directed to methods for evaluating the efficiency of inject-soak-produce gas injection methods for oil recovery in unconventional reservoirs. In one embodiment, a method for evaluating the efficiency of oil recovery from an unconventional reservoir rock sample includes characterizing the rock sample by imaging the rock sample using a nano-CT scanner and/or scanning electron microscopy (SEM); cleaning the rock sample by flowing solvent through it; saturating the rock sample with crude oil; and establishing initial water saturation in the rock sample.

Abstract

Improved methods and systems for efficiently and accurately modelling geological formations are disclosed. A geological model of a region of interest comprises a parent region having a plurality of child regions. A geological model of the parent region is designed. One of the plurality of child regions is extracted from the parent region while maintaining a first parent- child relationship between the child region and the parent region. The geological model of the child region may then be refined or manipulated. The geological model of the child region is then reintegrated with the geological model of the parent region.
