... the influence of both the viscosity of the fluids and the geometry of porous media. This quantification is the main difficulty in permeability and saturation modeling, and in explaining fluid and electric flow. Since the analyses contemplate the connectivity among the different capillary routes, a brief...

...), 8 % using gas lift and 7 % using all other forms of lifting systems. This study was undertaken using advanced predictive methods, high strength rods, optimum pumping mode, and unit geometry to optimize the performance of beam pumping system for deep high volumes oil wells. Three geometries...

... application of this proven technology. Sparse spatial sampling and wide azimuth geometry can be used to apply seabed logging to find and accelerate delivery of new prospects in frontier areas. In this paper, we evaluate the costs and benefits of various geometries and show results from the Campos basin...

... on the internal geometry of the rock; and, third, because numerical simulation of such reservoirs require reliable values of matrix porosity, fracture porosity, and block size. Naturally fractured reservoirs are complex systems whose flow properties are not well understood. From the fluid transport viewpoint...

... = ∆ρg; µ is liquid viscosity; u(x,y) is the flow velocity in z direction and Eq. 1 can be transformed into Laplace’s equation 21 . Many solution techniques may be used to solve Eq.1 , depending on boundary conditions and the geometry, Analytical solutions are available for circular, rectangular...
