... The pentane was used as the oil phase in all experiments. The sodium dodecyl sulfate (SDS) was used as the surfactant. And the N-butanol was used as the co-solvent. Potassium chloride (KCl) was used to control the salinity of the surfactant solutions. Three microemulsion-forming surfactant...

... The first series of experiments tested the long-term durability of various resin formulations at an application temperature of 175°F cured in an 11.0 lb/gal CaCl 2 brine as well as a representative non-aromatic hydrocarbon. The non-aromatic hydrocarbon chosen for this testing was nondetergent 30...

...-psi back pressure regulator was added to hold vapor pressure of water plus any CO 2 fugacity (i.e. above the bubble point) under our experimental conditions. Before each experiment, the solution compositions were calculated using ScaleSoftPizer (SSP) software developed by Rice University, Brine...

... pressure was expected to increase from the BL when T1> T2 and remain constant when T1=T2. The difference in pressure (cutoff – baseline) ranged from 8000 to 3000 PSI depending on the experimental condition. The cutoff of 10,000 PSI was used in experiments due to the pressure ranges of backpressure valve...

... in heterogeneous porous media Foam flooding experiments in heterogeneous porous media were conducted to evaluate the sequestration of CO 2 and CFA. The schematic diagram of oil displacement experimental apparatus is shown in Figure 2 . The aqueous CO 2 foams were generated by co-injection of gas...

... was performed at experimental conditions discussed previously. Since the diffusion coefficient and reaction-rate coefficient are needed to run the simulation, but are not available before running the experiment, the values were obtained from the literature ( Peng et al. 2015 ; Kotb and Nasr-El-Din 2020...

..., there are shortcomings and problems in the design of experimental steps in some literatures. For example, in the dynamic gelation experiment between crosslinking agent and polymer molecular chain, when the experimental temperature is higher than 60 °C, the rate of crosslinking reaction is very faster, and the polymer...

Experimental Procedures Static Bottle Test The static bottle test was used to evaluate the brine/fluid compatibility and inhibition performance of the inhibitors under static conditions. It was conducted...

... shows the water saturation profile during the displacement of DME and brine. As shown in the scale, red corresponds to higher water saturation and dark blue corresponds to lower water saturation. The two experiments have the same experimental samples and CT scanning parameters. It can be seen...

This study also addresses the interactions between the tested iron-control additives and acid, as well as the performance of the chelants in carbonate cores. Laboratory experiments were conducted to investigate the performance of nitrilotriacetic...

... was first carried out. Then after the mixing of oil and ASP, the distribution ratio of agent was analyzed. Lastly, the experiments of oil displacement effect evaluation and dynamic interfacial tension test were carried out. Experimental condition Experimental materials The flooding agents...

The experimental results show that surfactant has both advantages and disadvantages on imbibition. The advantage...

... concentration and, as observed for BaSO 4 , an improved performance in dynamic efficiency experiments. However, at higher HPAM concentrations (500 ppm) the precipitate was amorphous and only a minor pressure rise was observed during the tube blocking experiments. From these observations, it is clear that HPAM...

Hydrothermal reactor Experimental Procedure In previous research, laser apparatus was developed to replace turbidimeter for systemetic evaluation of induction time of barite under various SI values, Ba/SO4 ratios, inhibitor concentrations and pH, from 4°C to 70°C...

... is generally colder than the reservoir rock; this results in thermal gradients along the flow path. The temperature variation has an impact on CO 2 solubility and the kinetics of any mineral reactions. Core flood experiments and associated reactive transport simulations were conducted to analyse thermal...
