EOR/IOR terminology – time for a (real) change? EOR vs. IOR – Time for a Change. On August 1, 2024, the SPE community issued a call for public input on proposed changes to IOR/EOR terminology. Surveys revealed a limited understanding of these terms, highlighting the need for clearer definitions. However, the new proposals—introducing an additional term, AOR (Assisted Oil Recovery)—have raised concerns about adding

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.

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”.

In a previous post, I wrote that resuming water injection after polymer would only lead to a deterioration of the project economics/benefits. Now, how much to inject and when to stop?
