Boost Recovery. Cut Water. Act Early.
From diagnosis to execution, Eppok delivers Chemical EOR and Water Shut-Off solutions that reduce water cut, accelerate oil production, and improve recovery factors — faster, safer, smarter.
Polymer Flooding & Chemical EOR
Polymer flooding boosts oil production rates and can increase recovery by over 10% of the original oil in place compared to waterflooding, while reducing water production.
Conformance and water shutoff treatments improve sweep efficiency and can significantly extend field life by reducing unwanted water production, allowing more oil to be recovered with lower operating costs and improved production sustainability.
Conformance & Water Shut-Off
Why most oilfields leave millions of barrels behind
For 90+ years, the oil industry has relied on the Primary → Secondary → Tertiary staged recovery playbook. It leaves 60–65% of oil in the ground, drives WOR to 4:1+, and locks in high energy & CO₂ costs.
Why?
Heterogeneity ignored early — injected water takes high-perm shortcuts, bypassing oil-rich zones.
Poor early characterization — waterflooding for years “to learn the reservoir” lets conformance issues get entrenched.
Copy-paste fixes — designs from other fields fail when local geology is different.
By the time “tertiary” starts oil is harder to mobilize and water channels are permanent.
Our approach
Eppok delivers Polymer Flooding, Water Shut-Off, and Conformance strategies that prevent early water breakthrough, maximize sweep efficiency, and accelerate oil production — without waiting for the “tertiary” phase.
We break the cycle by integrating EOR and conformance control early, while saturation and pressure are still in your favor. And if your field is already mature, we bring targeted designs to squeeze the last drop while cutting excess water and operating costs.
Our services
We provide end-to-end support — from targeted training and asset screening to in-depth diagnostics that uncover the true causes of production loss.
Our solutions combine field-proven methods with integrated technologies and fresh ideas, backed by independent laboratory services for polymer and conformance testing.
We follow through with design, implementation, and field support to ensure each project delivers measurable, lasting gains.
During the preceding week, I engaged in an instructive training program led by Antoine THOMAS, which comprehensively addressed reservoir conformance and water shut-off methodologies. Prior to this course, I maintained skepticism towards the efficacy of conformance treatments and water shut-off strategies, subscribing exclusively to the belief that polymer floods held the sole solution to rectifying conformance challenges. However, following the acquisition of fresh knowledge and insights, our forthcoming endeavors will entail the pursuit of enhancements within our mature oil fields. We extend our sincere gratitude to our esteemed mentor, Antoine THOMAS, for his invaluable guidance.
In conclusion, I wholeheartedly endorse this course to fellow oil field engineers, as it equips participants with essential insights and tools for optimizing reservoir performance.

As the major world’s oilfields aging, excessive water production became a common problem. The good news that this issue can be mitigated relying on systematic and consistent engineering approach.
Kudos to Antoine THOMAS who has delivered comprehensive water shutoff and conformance control course. The course dives into aspects of water problem diagnostics, approaches to tackle different water problems, treatment selection, design and recipe selection.
With broad experience across multiple countries and perfect teaching skills of Antoine, I highly recommend all my network connections who are interested to learn WSO & conformance control to reach him out and benefit of well packed insightful course.

The course is excellent on several aspects:
The course is well paced, easy to follow
It reaches its target to give a detailed overview of what is EOR using polymer injection
It guides you through the steps you should follow if you are considering this method for your reservoir. This is very valuable if you want to evaluate the implementation of this EOR method.
As a reservoir engineer I found the content well adapted to my existing knowledge and felt that I learnt a lot and efficiently As a manager, I now feel comfortable to lead a corresponding study. As an instructor myself who has published a series of online courses on Well Performance / Gas Lift / ESP, I think that Antoine made a great job with this course and recommend it to everyone looking to understand what is EOR using polymer injection.
