... Abstract The Lloydminster Heavy Oil Block is the main source of Canada's conventional heavy oil production. The most common methods of recovery in this area are primary production, waterflooding, and chemical-enhanced oil recovery (EOR) such as polymer flooding. Although heavy oil waterfloods...

... Abstract Polymer flooding has been applied successfully in many water-wet, viscous oil reservoirs. When the reservoir is intermediate-wet or oil-wet, the polymer dosage has to increase to keep the displacement front stable, which adds to the cost. Alkali can generate in-situ soap, which lowers...

Thirdly, typical ASP flood performance and reservoir management measures from over 30 years’ experience are presented. In addition, performances of ASP flood and polymer flood in the same...

... Figure 3 Polymer flood study and applications in the La-Sa-Xing Field. In-House Study In-house studies including several laboratory tests and reservoir simulations were conducted to select the most appropriate polymer chemical structure, to understand the control of polymer flood...

... Abstract Low salinity waterflooding improves displacement efficiency in initially oil-wet reservoirs if it can alter wettability, but it is often a slow process. Polymer flooding usually does not improve displacement efficiency, but enhances sweep efficiency. In this work, the synergy between...

... Abstract The paper describes the in-situ polymer sampling in Mangala which helped explain the performance of a large polymer flood in Mangala field in India. The Mangala field contains medium-gravity viscous crude oil. Notably, it is the largest polymer flood in India and 34% of the STOIIP has...

... Abstract Experimental data in numerous publications show that viscoelastic polymers can significantly reduce residual oil saturation under favorable conditions. The effect of viscoelasticity is in addition to improved sweep efficiency of polymer flooding. The residual oil saturation decreases...

... reduction to chase fluids (usually water) following a polymer flood. These phenomena are more prevalent in high molecular weight polymers. The effects of R RF are also sometimes evident when polymer injection is suspended (e.g., operational issues) and other fluids are injected in the formation instead...

... Abstract Recently, modern streamline simulation has been extended to polymer flooding. In this work, we extended the applicability of streamline simulation further to efficiently manage polymer injection projects. We first present our methodology and then demonstrate the applicability of our...

... Abstract The successful design of a polymer flood relies on the ability to properly model the distribution of polymer concentration in the reservoir while accounting for effects on fluid properties such as water viscosity increases as a function of in-situ polymer concentration and loss...

.... This case history describes a large oil producing system that once had an extensive history of no corrosion related problems in the production equipment. Shortly after a polymer flood was initiated, some wells began to encounter severe corrosion problems. Standard corrosion control programs were...
