In the experiment, the interfacial tension of Hg is 485 mN/m, the contact angle is 140° and the maximum injection pressure is 900 psi, such that the corresponding minimum of pore throat radius is 0.12 μm.
Based on the FE-SEM and image processing technology, parameters like porosity, the ratio of the maximum to the minimum of pore orientation frequency, the content of cement, the ratio of the maximum to the minimum of cement orientation frequency and the fractal dimension of reservoir space could be applied into the microscopic heterogeneity characterization.
The effect of the minimum size of pore accessible to different adsorbates on kinetics prediction is investigated.
For a minimum of $50 an hour he'll do things like pore over the hundreds of annual plea letters, prepare evaluation reports on the impact of grants and organize site visits.
IFT ratios indicate that at the minimum impact of pore throat sizes to increase capillary pressure, IFT in the oil side can be as high as 140 times the IFT values in the gas side.
Passage of single particles through a pore causes a transient change of the pore resistance, called a resistive pulse.
Equation 7 shows that the minimum radius of empty pores after water expulsion decreases as ΔP gas increases (Fig. 4b).
From comparison of the ratios of the specific capacitances with those of the surface areas due to pores with sizes larger than certain values, the minimum size of the pores able to host the electro-adsorbed ions at the double layer is deduced; it results to be 0.56 0.58 nm for BF4−, 0.63 0.65 nm for Et4N+, 0.75 0.76 nm for Pr4N+ and 0.9 1 nm for Bu4N+.
Magnetoliposomes were obtained using a modified version of the phase-reverse method followed by extrusion at room temperature into a Liposofast device (Avestin, Inc., Ottawa, Canada) through two polycarbonate membrane filters of 0.2-μm pore size, a minimum of nine times both ways [14].
The BIP fills the pores of a millipore membrane, 125 μm, with a pore size of 0.45 μm [ 3].
