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 … Witryna28 lut 2024 · Spontaneous water imbibition is an important mechanism in water-wet fractured reservoirs. For volume-fractured reservoirs, to evaluate the oil productivity and oil recovery through water counter-current imbibition, we propose an analytical method for optimizing the reservoir volume fracturing scheme. Based on the two-phase fluid …

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. Witryna4 sty 2024 · Imbibition is an important mechanism to improve the recovery factor (RF) of a tight oil reservoir. Accurately evaluating the oil production capacity of tight oil reservoirs by imbibition is of great significance for the formulation of oilfield production plans and productivity prediction. However, there is currently no unified regulation on the …

WitrynaThe original water distribution characteristic plays an important role in the fracturing liquid retention in actual tight reservoirs. In this paper, an analytical model was proposed to characterize the water distribution and its effect on the spontaneous imbibition, based on the capillary tube model and fractal theory. Furthermore, the effect of the water film … high back patio furniture coverWitrynaimbibition gas-brine relative permeability (relperm) on reservoir core samples, e.g. as recommended by McPhee et al. (2015) it is very difficult to establish uniformly progressing brine saturation. This often leads to poor definition of the shape of the relperm function at lower brine saturations when gas has the highest mobility. how far is jesup ga from meWitrynaIn nature, a fascinating example of structural color is the blue color in fauna which is achieved by hierarchical nanostructures. ... The imbibition properties are governed by the surface properties of the porous template. This includes surface charge and hydrophilicity as well as the pore size. Additionally, the surface roughness influences ... how far is jessup mdWitryna5 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). high back patio dining chairsWitryna29 sty 2024 · Most rock in a natural reservoir is mixed-wetted, but most studies on the pore-scale imbibition process only focused on the water-wetted rock.
