Optimized polymer enhanced foam flooding for ordinary heavy oil reservoir after cross-linked polymer flooding
A successful cross-linked polymer flooding has been implemented in JD reservoir, an ordinary heavy oil reservoir with high permeability zones. For all that, there are still significant volumes of continuous oil remaining in place, which can not be easily extracted due to stronger vertical heterogeneity. Considering selective plugging feature, polymer enhanced foam (PEF) flooding was taken as fo...
متن کاملOptimal Control of Polymer Flooding Based on Maximum Principle
Polymer flooding is one of the most important technologies for enhanced oil recovery EOR . In this paper, an optimal control model of distributed parameter systems DPSs for polymer injection strategies is established, which involves the performance index as maximum of the profit, the governing equations as the fluid flow equations of polymer flooding, and the inequality constraint as the polyme...
متن کاملSimulation Study of Salinity Effect on Polymer Flooding in Core Scale
In this study, simulation of low salinity polymer flooding in the core scale is investigated using Eclipse-100 simulator. For this purpose, two sets of data are used. The first set of data were adopted from the results of experimental studies conducted at the University of Bergen, performed using Berea sandstone and intermediate oil. The second data set, related to sand pack and heavy oil syste...

In this paper, taking account of the major physical and chemical mechanisms, such as: for polymer, shearing propertypermeability reduction, adsorption, inaccessible porous volumes, for gel, gelation speed, water viscosity changing with gel, permeability reduction, adsorption and retention in reservoir rocks, a three-dimensional, three-phase (oleic, vapor, aqueous) and six-component mathematical...
متن کاملPotential for Polymer Flooding Reservoirs with Viscous Oils
This report examines the potential of polymer flooding to recover viscous oils, especially in reservoirs that preclude the application of thermal methods. A reconsideration of EOR screening criteria revealed that higher oil prices, modest polymer prices, increased use of horizontal wells, and controlled injection above the formation parting pressure all help considerably to extend the applicabi...
