Why is it so Difficult to Predict Polymer Injectivity in Chemical Oil Recovery Processes?0 DownloadsPolymer injection to improve and/or accelerate oil recovery is a widespread technique with numerous ongoing and successful projects. In recent years, many field cases have been reported with injected polymer viscosity ranging from 5 to 160cP, producing large incremental oil volumes, […]
Fractional Flow Calculations – Excel Spreadsheet0 DownloadsFractional Flow Calculations – Excel Spreadsheet is a good benchmark to assess the potential of injecting polymer to improve oil recovery. Fractional flow calculations are just a simple guide, and there are certainly things they can’t do. Simulations, on the other hand, can offer much deeper insights—provided they are

Breaking the Mold: Reassessing Polymer Flooding and the Outdated ‘Primary, Secondary, Tertiary’ Model0 DownloadsWords shape our thoughts, influence perceptions, and drive actions. The language we use frames how we interpret experiences and make decisions, shaping realities and guiding industry practices. In the oil industry, one example of this influence is the long-standing “Primary, Secondary, and
Revisiting Water Injection Post-Polymer Flooding: A Global Perspective on Project Performance0 DownloadsThis paper aims to synthesize theoretical insights and field experiences concerning water injection efficiency following polymer flooding. The objective is to summarize fluid and reservoir dynamics during this critical transition to guide the design of cost-effective and technically robust enhanced oil recovery (EOR) projects.

Successful Polymer Selection for CEOR: Brine Hardness and Mechanical Degradation Considerations0 Downloads2017. SPE185418. The selection of the right polymer chemistry in chemical enhanced oil recovery processes is key to successfully increase oil recovery. To start the screening process, it is necessary to look at minimum 3 parameters including brine composition, reservoir temperature and permeability. In
