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

Polyacrylamide gel electrophoresis (PAGE) analysis can be conveniently applied to analyze the molecular weight of sulfated GAGs. Gels on which GAGs have been fractionated can be visualized with Alcian Blue with or without silver staining and the bands can be scanned and digitized. The average MW of a GAG is then calculated based on a mixture of HP-derived oligosaccharide standards prepared
Polyacrylamide Drilling for Kuwait oil industry
Polyacrylamide in Oilfield Sinofloc Chemical. Polyacrylamide is a versatile chemical treatment agent in oilfield. In oil extraction it could be used as a flooding agent, water shutoff regulator, drilling fluid regulator, fracturing fluid additives, especially in cementing, completion and workover.
1. Introduction. Over the past several decades, many EOR methods were researched in laboratories and oilfields to improve oil recovery, for example, polymer flooding [], surfactant flooding [], alkali-surfactant-polymer (ASP) flooding [], nanoparticles [4, 5], low salinity water flooding [], and CO 2 [7, 8].However, polymer flooding is most commonly applied in oilfields, especially hydrolyzed

Figure 1 b shows a 2-dimensional structural model of the tool, which is mainly divided into contraction, cylinder, and diffusion sections. The middle part of the tool is the region where the solution flows through. The flow of ASP solution in the tool can be seen as a flow process that first contracts and then diffuses in a pipeline with variable cross-sections.
