... In this work, build on previous efforts reported in ( AlSofi et al., 2015 ) and complement the methodlogy and results especially in terms of presentation. We firstly demonstrate the decomposition of those two effects and its utility. We first reexamine the definitions of sweep efficiency...

... the Middle East. Saturation modelling and reservoir rock typing is based on uniform and heterogeneous Pc and kr distributions, and further employs a state-of-the-art software that integrates of SCAL data and log-derived saturations. Sweep efficiency and dynamic Lorenz coefficients are then derived from...

... increase their surface contact area, while it also leads to earlier breakthrough time and less sweep efficiency if such instabilities develop too severely. Especially at very large mobility contrasts, the less viscous injected solvent can easily bypass the highly viscous heavy oil. Most of the previous...

..., field injectivity tests, pilot water injection and intensive surveillance plan. Water injection is part of field redevelopment plan and will increase recovery factor by 7.3%. Upstream Oil & Gas mobility ratio sweep efficiency fracture pressure injector viscosity producer enhanced...

... Reynolds number, the fluid reaches into the dead pore even much deeper. The simulation results indicate the contribution of the viscoelasticity of polymer solutions to the micro-scale sweep efficiency. The non-dimensional model of simplified pore structures will contribute to the selection of suitable...

... sweep efficiency, and low mobility ratios, all of which can dramatically impair oil recoveries. Vast amounts of remaining oil-in-place have led operators to analyze opportunities to improve WF management and production. This paper presents an approach to increase recovery and improve performance...

... result shows that emulsification role is favor of further improvement of displacement efficiency on middle-high permeability layer, moreover, it could enhance sweep efficiency of low-middle layer. Alkaline scale could decrease inject capability of injection wells and produce capability of oil wells...

.... – Define and quantify the volume of fluids-in-place, movable oil, residual oil and volumetric sweep efficiency to assess the reservoir potential, rate sustainability and economic ultimate recovery. – Assess the associated risks to development plans under selected development schemes with water/gas...
