Abstract: A core holder for core testing includes a body having a cavity. A sleeve is disposed within the cavity. The sleeve defines a chamber to hold one or more core plugs. One or more fiber-optic sensors are disposed at a perimeter of the chamber. Each fiber-optic sensor senses a parameter related to flow of fluid through the chamber. A core testing system includes one or more light sources to provide light to each fiber-optic sensor and one or more light detectors to detect light from each fiber-optic sensor. A method of core testing may include injecting a fluid into one or more core plugs inside the chamber and measuring one or more parameters related to flow of fluid through the one or more core plugs.

Abstract: A core flooding system includes a core holder that encloses a core sample of a subterranean formation. The core holder includes a fluid inlet and a fluid outlet; at least one sensor coupled to the core holder or positioned in the inner volume of the core holder; an acoustic vibrating assembly coupled to the core holder; and a control system communicably coupled to the at least one sensor and the acoustic vibrating assembly. The control system performs operations including operating the acoustic vibrating assembly to transmit at an acoustic wave energy or a vibration energy to the core holder; during the transmission of the at least one of the acoustic wave energy or the vibration energy to the core holder; measuring at least one parameter of the core sample; and based on the at least one measured parameter, determining at least one property of the core sample.
