An inverse transformation is performed on (7), and the capillary pressure
curve of each rock type can be obtained.
Contact angle is the most controversial parameter in fluencing capillary pressure
. The uncertainty observed in experimental measurement on different rocks at a wide range of GCS thermodynamics results in a high risk of leakage and low storage efficiency in GCS projects.
where Se: effective saturation, [[psi].sub.b]: bubbling pressure, [psi]: capillary pressure
that corresponds to moisture [theta], and [[psi].sub.e]: air entry pressure.

For the liquid-gas interface at the downstream edge, the expression for the capillary pressure
within a film forming surface of Ruschak (11) was applied.
In order for the loop to continue to function, the wick in the evaporator must develop a capillary pressure
to overcome the total pressure drop in the loop.
During the vacuum suction the impregnation starts when a pressure on the boundary "fine fraction salt-melt" reaches the value of capillary pressure
, that is, when it exceeds sufficiently a capillary pressure
for the basic NaCl layer (or the pressure of destruction of oxide films).
Among specific topics are particle-surfactant interaction at liquid interfaces, the assembly of non-aqueous colloidal dispersions under an external electric field, low-density solid foams prepared by simple methods using highly concentrated emulsions as templates, capillary pressure
experiments with single drops and bubbles, and thermodynamics and specific ion effects in connection with micellization of ionic surfactants.
The low capillary pressure
under these curved menisci can deform soft particles during this "wet" drying stage.
The JIP will focus on the following key issues: relationships between facies, depositional sequences and reservoir quality; shale pore types and their effect on total porosity and permeability; porosity-permeability trends for individual Utica and Point Pleasant facies; relative permeability and capillary pressure
behavior; and linking core-derived reservoir quality to well logs and well productivity.
However, tissue pressures greater than capillary pressure
can be endured for some time before ischemia results .
The following variables were measured: MAP, stop flow pressure (SFP), transcapillary hydraulic pressure ([data]P), hematocrit (Hct), free flow pressure (FFP), capillary pressure
(PC), and afferent (CA) and efferent (CE) protein concentration.
The wettability of a rock controls the location, flow, and distribution of fluids within reservoir rocks , which affects the relative permeability and capillary pressure
Critical parameters, that is, infiltration pressure [P.sub.in], defiltration pressure [P.sub.de] advancing capillary pressure

[P.sub.r], pressure when infiltration ends [P.sub.max], pressure hysteresis [DELTA][P.sub.PhyS] = [P.sub.max] - [P.sub.de] = [P.sub.a] - [P.sub.r], pressure span [DELTA][P.sub.pla], and volume span [DELTA][V.sub.pla] of the plateau, with [DELTA][P.sub.pla] = [DELTA][V.sub.pla] x [S.sub.pla], are clearly indicated and defined in Figure 2(b).
