Important equations – water shutoff and conformance2 DownloadsThis Excel spreadsheet from Randy Seright compiles the essential equations and technical formulas used in the design, evaluation, and optimization of water shutoff and conformance treatments in oil and gas reservoirs. It is intended for reservoir engineers, production engineers, and field practitioners who work with gels, relative permeability […]

Breaking the Mold: Reassessing Polymer Flooding and the Outdated ‘Primary, Secondary, Tertiary’ Model0 DownloadsWords shape our thoughts, influence perceptions, and drive actions.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.

Calculating shear in vertical wells – python code25 DownloadsHere’s a code to calculate and plot the shear rate in python. The file is in PDF but code can be copied easily. Any feedback is welcome. Remarks: The code  provided is written in Python and uses the `tkinter` module for GUI. This code is compatible with

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

Selection of Customized Polymers to Enhance Oil Recovery from High Temperature Reservoirs0 Downloads2015. SPE177073,  This paper describes the selection and evaluation of polymers dedicated to high temperature reservoir conditions (from 85°C to 140°C) using very low salinity brine in comparison with harder brine. A series of rheological, shear and thermal stability tests have been performed

Performance of Associative Polymers in Porous Media0 Downloads2013. EAGE IOR> The propagation of associative HPAM polymers in porous media is greatly dependent on the degree of hydrophobic modification. In this paper, the transport properties of several associative polymers with degree of association from none to high were investigated in Berea cores and silica sand-pack cores.
