摘要： 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.

摘要： Embodiments of the present disclosure generally relate to apparatus, systems, and methods for characterizing fluid-solid systems. In an embodiment, a method includes placing a porous rock sample in a core holder, contacting the porous rock sample with a fluid to create a fluid-solid system inside the core holder, automatically adjusting a temperature and/or pressure of the fluid-solid system to a preselected value via a processor and at least one automated valve, monitoring the fluid-solid system for equilibrium, recording a value for temperature, pressure, and/or mass of the fluid-solid system, performing an action based on the recorded data, and repeating the adjusting, monitoring, recording, and performing operations to produce a thermodynamic data characteristic of the fluid-solid system. In one example, the performing operation includes analyzing a pressure signal for stationarity by performing an Augmented Dickey-Fuller (ADF) test and/or a Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test.

摘要： Embodiments of the present disclosure generally relate to systems, devices, and methods to model fluid flow in a porous medium. In an embodiment, a microfluidic device to model subterranean fluid flow is disclosed. The device includes a mold of solid material, the mold including a field of pores and throats formed in the mold for mimicking a porous rock formation, a peripheral channel formed in the mold for mimicking a fluid reservoir, and an interior channel formed in the mold for mimicking a well. The peripheral channel can trace a perimeter or circumference of the field of pores and throats and be in fluid communication with the pores and throats.
