“…They found that permeability was a function of both water flow rate and polymer concentration. Yang et al [18] developed a mathematical model for the flow of water through channels impregnated with a polymer gel. Their results indicated that gels' intrinsic properties (e.g., gel reference permeability and elasticity index) controlled water flow behavior.…”

h i g h l i g h t sPermeable gel-pack was formed in the large fluid channels by gel particles. A better gel blocking efficiency gained by optimizing gel strength and particle size. Gel pack permeability was a few hundred millidarcies before the load pressure. PPG is compressible and its compressibility was between 0.0003 psi À1 and 0.003 psi À1 . PPG formed internal channels when subjected to a continuous load pressure. a b s t r a c tA newer trend in gel treatments is using preformed particle gel (PPG) to reduce fluid channels through super-high permeability streaks/fractures and thus to decrease water production and increase sweep efficiency for mature oilfields. The success of a PPG treatment mainly depends on whether or not the PPG can effectively reduce the permeability of the channels to an appropriate level. This work sought to determine what factors significantly influence the blocking efficiency of PPG in fluid channels. A transparent filtration model was designed to observe the compression of gel particles in fluid channels at several differential pressures and to study the effect of various parameters, such as brine concentrations and particle sizes, on PPG blocking efficiency. The results suggested that rather than fully blocking the channel, a permeable gel pack was formed in the fluid channel by gel particles, and its permeability was dependent on the gel strength, particle size, and load pressure. The gel pack permeability decreased as the gel strength, particle size, and load pressure increased. Thus, the blocking efficiency of the particle gel on a channel is increased if large sizes or/and strong particles are used. The gel pack permeability was a few hundred millidarcies before the load pressure was applied; it decreased to less than 10 md when the load pressure rose. The results also indicated that the PPG pack was compressible and its compressibility decreased as the load pressure increased. These results can be effectively used to optimize a PPG design. A gel pack that has a desired permeability can be devised by selecting the proper gel strength and particle size corresponding to the reservoir pressure. This is essential for a successful gel treatment so as to reduce the permeability to a manageable preplanned degree.

“…Increased aqueous fluid velocities form larger spaces by deforming the elastic gel, thus increasing permeability. Yang et al (2002) also demonstrate that the permeability to water in such gels is an intrinsic property of the gel; polymer gel permeability depends on the gel elasticity/storage modulus. Chauveteau et al (2001), Feng et al (2003), Rousseau et al (2005), and Cozic et al (2009) can be referred to for additional insight on the physicochemical characterization of microgels.…”

“…It is important to realize that flow occurs through gels/microgels as if they are porous media Grattoni et al, 2001;Yang et al, 2002), and that the gel internal permeability is velocity dependent. When an imposed pressure gradient is greater than the forces of interaction that hold a gel in place, it was found that aqueous fluid can flow through the gel network.…”

The flow of a non-Newtonian fluid through a porous media in between two parallel plates at different temperatures is considered. The governing momentum equation of third-grade fluid with modified Darcy's law and energy equation have been derived. Approximate analytical solutions of momentum and energy equations are obtained by using perturbation techniques. Constant viscosity, Reynold's model viscosity, and Vogel's model viscosity cases are treated separately. The criteria for validity of approximate solutions are derived. A numerical residual error analysis is performed for the solutions. Within the validity range, analytical and numerical solutions are in good agreement.
