High pressure core chamber for reservoir experiments
A recently granted patent (Publication Number: US11965872B2) discloses a method for determining the wettability of a core sample collected from a reservoir. The method involves placing the core sample in a high-pressure chamber with various sensors and ports, injecting test fluids, measuring pressure changes over time, and determining wettability based on the pressure data obtained. The process includes steps such as using different test fluids, ensuring pressure equilibrium before measurements, and subsequent analysis of the core sample's characteristics post-testing.
Furthermore, the patented method allows for the use of multiple test fluids, such as brine or stimulation fluids, to assess wettability accurately. It also includes additional steps like assaying core sample characteristics, conducting low-field NMR measurements on the core sample, and analyzing fluids exiting the core sample. By following this method, researchers and engineers can gain valuable insights into the wettability of core samples from reservoirs, aiding in the development and optimization of extraction techniques in the oil and gas industry.
