... Abstract Effect of retardation in fluid displacement on transport inside capillary tubes during leak-off and clean-up for hydraulically stimulated reservoirs is investigated by modeling of the relevant phenomena. The effect of wall proximity during the transport in narrow capillaries...

... Certain aspects of fluid displacement design in a vertical well evidently carry over to horizontal well cementing, e.g., the preference for turbulent fluid displacement. However, in extended reach wells the ability to displace in the turbulent regime is often restricted by pore-frac pressure...

... Less costly than cementing large casing with the conventional plug-displacement method. Does not require large-diameter casing plugs. Reduces cement contamination. Reduces amount of cement to be drilled out. Decreases cementing displacement time. Reduces casing collapse when...

... by the layers of high viscosity gel that are created by the viscous fingers. This also allows the proppant to be placed deeper in the fracture, than if the displacement were stable. The proppant horizontal flow velocity will be much higher than proppant carried by the gel due to the much higher fingering...

... because of the relatively low viscosity of the gas. This paper demonstrates how these differences affect the penetration of acid into the formation and the distribution of acid along the wellbore (acid placement). When acid displaces gas in the formation around the wellbore, the favorable mobility ratio...

... Abstract Carbon dioxide has been used in oil reservoirs for multiple contact miscibility, with methane or nitrogen as the displacing fluid. Carbon dioxide has also been used as an additive for fracture fluids to promote flow back and even as a base fluid for fracturing. A miscible process has...
