Study on Microscopic Distribution Law of Remaining Oil after Polymer Flooding based on Polymer Flooding Control Degree

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...

Optimal 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...

Simulation 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...

Full Implicit Numerical Simulator for Polymer Flooding and Profile Control

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...
