Spontaneous imbibition, a process where a wetting fluid is drawn into a porous medium by capillary action, is the primary oil recovery mechanism for various subsurface processes, including water infiltration/flooding in naturally fractured reservoirs and fluid exchange between hydraulic fractures and rock matrix in unconventional reservoirs.
Our custom-designed Amott cell imbibition setups offer testing at elevated temperatures (up to 200°F) with a wide range of aqueous solutions, including those with chemical additives. Our setups are capable of handling both conventional and unconventional samples, including those with ultra-low permeability and pore volume. We ensure precise measurements with resolutions down to 0.01 ml. We follow rigorous in-house procedures for saturating and conditioning/aging reservoir core samples with reservoir crude oil. This meticulous preparation ensures that our samples accurately represent the saturation levels and native wettability of your reservoir, providing reliable and relevant test results.
