Thief Zones: Not All Are Created Equal

Leave a Comment / Food for thoughts, General, Uncategorized /

Thief Zones: Not All Are Created Equal. In conformance control, it’s often assumed that injected gelant will neatly find its way into the “thief zone” and solve the problem. But here’s the reality many don’t expect—especially in multilayered, open-hole wells, or horizontal wells. When your thief zone is a matrix feature (high permeability channel for

Rethinking EOR: Why It’s Time to Abandon the “Primary, Secondary, Tertiary” Model

Rethinking EOR: Time to Abandon the Primary Secondary Tertiary Staged Approach. After years of working on polymer flooding and chemical EOR, I’ve come to believe that one of the biggest barriers to better oil recovery isn’t technical—it’s psychological and historical. That’s why I put together this presentation: to challenge the long-standing primary / secondary /

Early polymer flooding achieves higher recovery factors, reduces water cut, and maintains stable injectivity, whereas tertiary flooding struggles with injectivity challenges and inefficiencies inherited from prior waterflooding

EOR/IOR terminology – time for a (real) change?

Leave a Comment / Food for thoughts, General, Polymer News /

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

A conversation on microgels, nanogels, and other products in inverse emulsion form

Leave a Comment / Food for thoughts /

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.

Revisiting polymer selection workflows for chemical EOR

Leave a Comment / Food for thoughts /

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.
