... was experimentally tested in the loading NPs from 0.01 wt% to 0.5 wt% by the contact angle method. Wettability studies have shown that nanofluids can influence wettability variability from oil-wet to water-wet quality. About 0.05 wt% of NPs was found to be the optimal concentration to affect wettability change...

... for “dense” mixtures. Upon the validation of the bulk diffusion results with the theoretical calculations, the results of the hydrogen-methane diffusion experiments were carried forward to the evaluation of the diffusion through porous media experiments. In this section, the experimental setup...

... of the experimental setup used to determine the minimum capillary pressure (MCP). The improvements on this design were based on the work by Hawthorne et al. (2016) . Three capillary tubes (World Precision Instruments) with inner diameters of 1.12, 0.84, and 0.68 mm, respectively, were used in the experiment...

... wettability and the performance of different brines as EOR fluids. The imbibition experiments were performed at 90 and 110°C at a backpressure of 10 bar using FW, SW, DW-PS, and SW-PS as the imbibing brines. The volume of oil produced was calculated as %OOIP vs. time. The experimental setup is depicted...

... oil in a 2D sandpack. Over 20 nonionic surfactants/cosolvents were tested. A series of sandpack flooding experiments were conducted in a custom-designed 2D visualization cell. The results show that short-hydrophobic surfactants 2EH-xPO-yEO can reduce the IFT to as low as 0.05 dyne/cm. Flooding...

.... In terms of applicability of these ML models, two sets of experimental data were needed as input; the first was the analytically estimated K r curves from the steady-state drainage coreflooding experiments, while the other was the P c curves estimated from centrifuge or mercury injection capillary pressure...

..., polymer flooding is mainly dependent on the heterogeneities of the reservoir. The aim of the two-phase flow experiments was to investigate the 1D displacement efficiency and the interaction of in-situ generated soaps and alkali solutions increasing the pH and polymers. The experimental setup is shown...
