YouTube Channel – Polymer Flooding Academy 🚀 Big Announcement: Polymer Flooding Academy YouTube Channel ! I’m thrilled to introduce a new YouTube channel focused on Chemical Enhanced Oil Recovery (EOR), Polymer Flooding, Conformance, and Water Shut-Off, with some extra 🙂 This channel will serve as a one-stop resource for professionals, researchers, and students looking to expand their knowledge and stay up to date with
🚀 Big News! I’m excited to announce the launch of the Polymer Flooding Academy, a dedicated platform for training, knowledge sharing, and industry insights. We will discuss Polymer Flooding, Chemical EOR, Conformance, Water Shut-Off and more. This academy is designed to provide valuable, practical content for reservoir engineers, researchers, and industry professionals looking to deepen their expertise in Enhanced Oil Recovery (EOR) and stay up-to-date with
Microgels and nanogels used for conformance are trending on some parts of the world. When facing significant permeability contrasts (think 10:1), spot treatments with these particles might be an interesting idea to explore before heading straight into polymer flooding. But this isn’t a simple plug-and-inject operation.

I tried to revisit the polymer selection workflows for chemical EOR, showing that a majority of tests could be more representative of the reality in the field. Working on new industry standards would greatly benefit all the researchers. Also, understanding the logic behind the tests and what they were initially designed for would save time and avoid disappointments.

Difficulty to predict injectivity in polymer floods Difficulty to predict injectivity in polymer floods. 📄 Analyzing the 2019 Paper: “Why is it Challenging to Predict Polymer Injectivity During Chemical EOR Processes?” Difficulty to predict injectivity in polymer floods. Injectivity remains one of the most debated topics in polymer flooding, often misunderstood or oversimplified in simulations.

21/02/2023 Polymer Flooding Current Status and Future Directions: A great paper – straight to the point! Seright & Wang, 2023. Abstract: “This review presents our perspective on the factors that have brought polymer flooding to its current state. Insights are provided on why HPAM is the dominant polymer used as well as what is needed

Polymer retention is one of the most critical parameters for the success of a polymer flooding project. A high retention means a poor propagation and therefore a delay in the oil bank production but also a much lower viscosity at the front, creating instability.
For instance, @1000ppm and with a retention of 50 µg/g in a sandstone, that’s already a 40% delay factor in % of pore volume. At 3$/kg of polymer in a 40 acres/20ft thick zone, it’s a bit more than 1,2 million USD to satisfy retention… (you can do your own spreadsheet using the SPE166265 for instance)
The first time I was confronted to the way polymer flooding was modeled, I was struck by the number of parameters needed and the complexity of the whole thing. It feels like everyone wanted to be sure to capture absolutely everything: from the molecular interactions to the rheological behavior. The first image that came to my mind was a DJ mixing table: a lot of buttons and no idea which to touch to obtain the desired music without the help of an “expert”.
