... Abstract In this paper, we developed a laboratory protocol to evaluate the performance of three microemulsion (ME) additives in fracturing water for enhanced oil recovery. We applied the protocol on oil, brine, and core samples from two wells completed in the Montney (MT) Formation...

... were then brine saturated in two steps of spontaneous imbibition followed by forced imbibition under vacuum. The Archimedes principle was used to measure the sample pore volumes. Porosity was subsequently calculated. NMR relaxation data were then acquired on the brine-saturated cores. Then the core...

... imbibition-recovery (IR) trio to investigate the recovery mechanisms in rocks with dual-wettability pore network. First, we evaluate the wetting affinity of five twin core-plugs from the Montney Formation by measuring spontaneous imbibition of reservoir oil and brine, and by measuring equilibrium contact...

... Abstract In this study, we evaluate the wettability of shale samples drilled in the Duvernay Formation, which is a source-rock reservoir located in the Western Canadian Sedimentary Basin (WCSB). We use reservoir oil and brine to conduct air-liquid contact angle and air-liquid spontaneous...

... indices. Cores saturated and aged with formation brine or surfactant solutions were first injected with Bakken crude oil (i.e., drainage process). Then the fluids in the cores were displaced by brine or surfactant solutions to obtain the imbibition capillary pressure curve. Multi-speed measurements were...

... powders are washed with DI (deionized water) sequentially. Individual ion concentrations are obtained by ICP-MS analysis. The ionic strength and Debye length of the brine obtained from each step of the washing experiment are calculated. Zeta potential of the fresh and washed powders are measured in DI...

... fields in North Dakota. Thousands of Middle Bakken wells have been drilled and produced in the primary production mode, yet there is likely significant potential for enhanced oil recovery, which prompted this multi-facetted research study. First, the physical properties of the reservoir brine, oil...

... Abstract Traditional methods of determining wettability such as the Amott and the U.S. Bureau of Mines (USBM) test for an oil/brine/rock system are difficult to apply to shales due to their extremely low permeability, usually in the nanodarcy range. Earlier Nuclear Magnetic Resonance (NMR...

... in high concentration brines. Several water treatment methods are being used in the industry to remove impurities from flowbacks for reuse as frac water for fracturing. However, most treatments do not remove dissolved salts from the water requiring either development of a brine tolerant friction reducer...

... Abstract The paper analyzed experimentally the production characteristics of hot-brine stimulation accompanying the hydrate reformation in the presence of methane hydrate. Many attempts have been to recover commercially the methane hydrate such as depressurization, thermal stimulation...

... It is important to have a scaling for the amount of dissolved CO 2 ; therefore, we introduce the cumulative dissolved CO 2 in brine. This amount is the combination of the CO 2 that is trapped in the segment at any time and the CO 2 that is dissolved and flows out of the segment. The amount of the CO 2 trapped...
