Different influencing factors in the process of polymer flooding have different degrees influence on development effect, so it is necessary to carry out dynamic prediction before implementing scheme. In this study, reservoir model C Block established and production performance fitted. The fitted used study concentration, injection time, rate multiple timing effect Block. results show that cumul...

The North Burbank Unit, located in Osage County, was originally discovered in 1920. It has an extensive history of activity, including primary depletion, produced gas cycling, and water and polymer flooding to the point of very high water cut at current conditions. The current oil production rate in the North Burbank Unit is approximately 1,400 BOPD from 360 active wells at a water cut of 99.5%...

The progress several commonly used agents introduced, including biopolymer, temperature salt resistant monomer polymer, hydrophobic associating cross-linked comb star polymer. Based on analysis properties, advantages disadvantages these polym...

Polymer flooding is one of the most important enhanced oil recovery (EOR) technologies for high temperature and high salinity reservoir. In this paper, an optimal control model of distributed parameter systems (DPS) 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 floodi...

recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...

In order to determine the matching relationship of polymer molecular weight and reservoir permeability in ASP (alkaline/surfactant/polymer) flooding, a number of core flooding experiments with different polymer molecular weights are performed. Two types of curves for the relationship between the pressure difference and the injection pore volume multiples are obtained. One describes the characte...
