Imbibition example
Witryna9 cze 2024 · Figure 8a,b shows the sample imbibition capacity in different states. It can be seen that the A formation sample (A1, A2, A3, and A4 samples) have a larger imbibition capacity in the dry state than that in the primitive state. In the B and C formations, the imbibition capacity in the dry state is approximately equal to that in … Witryna12 cze 2024 · Coal is a typical dual-porosity medium.

The imbibition rate is related to the mobilities ratio and can be either counter-current or co-current displacement [61,62,63,64]. The spontaneous imbibition mechanism is more efficient …
Witryna1 cze 2024 · For example, sample 1 has the highest porosity and second high permeability, while this sample's ultimate spontaneous imbibition efficiency is lower than that of sample 4 (Fig. 4, Fig. 6, Table 3). The samples with a high proportion of intergranular pores have relatively low imbibition efficiency, and different types of … WitrynaThe process of imbibition refers to saturation increase for the wetting fluid, regardless of whether it is ... Measuring Wettability. Measurements on core samples include spontaneous and forced imbibition and centrifuge capillary pressure measurements. If a core sample imbibes water spontaneously but not oil, it is water-wet; if a sample ...
Witryna19 sty 2016 · An example of capillary pressure relationships during drainage and imbibition for an unconsolidated dolomite powder is shown in Fig. 6. The wetting phase is water, and the nonwetting phase is decane. The imbibition curve remains above zero capillary pressure, similar to the typical form of Fig. 4. WitrynaThe imbibition model was verified with the experimental data on the rock samples in Group A under different interfacial tensions, with a salinity of 0 mg/L taken as the …
Witryna5 lut 2024 · In addition, the imbibition of fluid with additives was also different in various clay content shale samples. In the high clay content sample, the fluid with 0.07% friction reducer has a greater imbibed volume than the fluid with KCl or KCl substitute (choline chloride, magnesium chloride, and tetramethyl ammonium chloride).
