... and solid components in the bottle were collected separately using a 0.45 µm membrane filter. Chelating agent flooding experiments were conducted using a basalt core sample with diameters of 25 mm and lengths of 25 mm. The experimental system is shown in Figure 2. Prior to the experiment, the initial...

... uncertain. To address this knowledge gap, the present study investigated the dissolution behaviors of both altered and unaltered basaltic rocks in a brine that simulating the real reservoir condition with 5 MPa CO2 gas at 100 through laboratory batch experiments. The experimental results indicate...

... Corporation). The AE device with the sensor gathers acoustic signals through axial load pistons, an amplifier, and a computer for recording and processing. Figure 1: Experimental system. For the experiment, the polyimide-film-wrapped sample was first placed inside the PE cylinder within the triaxial cell...

..., September 14-15, 2022 Reproduction of experimental results Using the simulator thus constructed, we reproduced the performances of the core flooding experiments mimicking a Nano EOR process, to validate the functions of this simulator. The overview of the experiments is given below. For more details, see...

.... Experimental system and procedures Among the various kinds of chelating agents, Chelating agent flooding experiments were conducted environmentally friendly compounds such as N-(2- using the experimental system illustrated in Figure 1. In hydroxyethyl)ethylenediamine-N, N', N'-triacetic acid each experimental...

... experimental strengths have been utilized instead especially in case of offshore drillings. This is because the core recovery of deep-sea drilling is usually limited and destructive tests such as triaxial compression experiments can hardly be performed continuously with depth. In addition, it is also difficult...

... experiment using this simulator, it was confirmed that the experimental results could be reproduced accurately by considering mainly ion exchange and wettability alteration functions. It might suggest that those phenomena dominantly contributed to the oil recovery in one of previous core flooding experiments...

... for application at various geothermal conditions. In this study, three fracturing experiments were conducted on cylindrical granite samples at 200°C and 450°C, with a range of differential stress, where liquid CO2, which was preheated to the experimental temperature before entering the borehole, was injected at 1...

The experimental conditions assumed commonly to GA and ILHS and the hypothetical two-phase (oil-water) relative permeability data are shown Table 1 and Table 2, respectively. Note that the values of halftone shading in Table 2...

... rate and the heat. Therefore, we made the flow experiment with a column and measured the heat of mineral dissolution with a differential scanning calorimetry. In this experiment, Toyoura sand as a sediment and hydrochloric acid were used. In based on those experimental results, we determined constants...

.... The combination workflow consisted of the following steps: 1. CMOST calls the simulator and calculates the objective functions for a set of experiments. 2. Once all existing experiments are completed, CMOST outputs the experiment table and calls the HMC program. 3. The HMC program reads the file and performs its...

EXPERIMENTAL CONDITIONS These comparative core flooding tests were conducted under 2000 psig of pore pressure and 77 °C of temperature throughout the experiment. First, the core sample was fully saturated with saline water, then 4.0 pore volumes (PVs) of n-decane...

... (effluent rates of each phase and differential pressure) were prepared by numerical simulation mimicking core flooding experiments. The relative permeability to oil was then tuned so as to rigorously reproduce these hypothetical experimental results. By appropriately combining the optimization methods...
