..., or local capillary pressure. The assumption of a sharp interface is to focus on the combined effect of mobility ratio and compressibility. We use the product of the fluid compressibility and pressure drop ( c f Δ P ) to differentiate the compressibility groups ( Dake 1978 ; Dranchuk and Quon 1967 ), where...

... in later sections for validation and testing of our proposed correlation. To test the effect of mobility ratio on dynamic Lorenz coefficient, the endpoint mobility ratios were varied from 1 to 1,000 in multiples of 10 (1, 10, 100, and 1,000). This was achieved by changing either the oil and/or water...

.... Grades allow engineers to place the popping agent in different locations of the thief zone. The grade of the product should be chosen by considering the temperature profile in the reservoir, interwell distance, injection rate, mean residence time, k v / k h , and mobility ratio, among other variables...

... fluid mobility. A series of experiments illustrated more-unstable structures for greater displacement velocity and viscosity ratios during forced displacement. The mobility ratio evaluated at the water-saturation shock predicted by Buckley-Leverett displacement theory was a good predictor of stability...

... parameters, such as fluid mobility, mobility ratio, 3D saturation distribution (in particular, shockfront position), 3D temperature distribution, positions of wells (producers, injectors), and geological details (e.g., layering and faulting). In particular, it is shown that lower overall (time-dependent...

...Mridul Kumar; Viet Hoang; Cengiz Satik; Danny Rojas Summary This paper presents the results of a comprehensive study to improve our understanding of high-mobility-ratio waterfloods (HMRWFs) and to improve performance prediction. Published data on heavy-oil water-injection field projects are limited...

..., and the performance is compared with that for Newtonian fluids. Constant-injection-rate and constant-total-pressure-drop cases are studied. The effects of the following factors on performance are investigated: the flow-behavior indices, the apparent mobility ratio, the Dykstra-Parsons variation coefficient...

... a horizontal producer (HP) and a vertical injector (VI). The HP has its horizontal leg located at the top of formation, while its toe is close to the VI, which is perforated at the lower part of the formation. TTHW realizes a gravity-stable displacement, in which the water/oil mobility ratio becomes less...

... the EOR process itself is nontrivial. This paper illustrates that geometric and geological factors are evaluated easily at unit mobility ratio. Subsequently, nonunit-mobility-ratio effects can then be predicted. In this fashion, the efficiency of the EOR process is decoupled from geometry and permeability...

... characteristics that control flow rates are described fully by a newly defined total mobility ratio, M T . The form of the new equations allows for modifications for skin effect and reservoir heterogeneity. We show how skin effect can act disproportionately with injectors and producers because of its interaction...

... that oil recovery could be increased by minimizing crossflow between layers by blocking the bottomwater zone. It also was found that for an unfavorable mobility ratio, as the injection rate increases, the ultimate oil recovery increases. The injection of a polymer solution had a favorable impact...

... ratio, mobility ratio and permeability variation. Analogy to the Buckley-Leverett (BL) multiple-valued saturation profile is found to occur at low mobility ratios ( M< 1) where a multiple-valued displacement front is formed. A procedure similar to the BL discontinuity is suggested to handle...
