Oil reservoirs productivity enhancement

Nowadays, oil producers are not satisfied with oil recovery rate from oil-bearing reservoirs: the average final oil recovery rate from oil-bearing reservoirs is 30 to 40%, while 60% of the resource base accounts for residual and hard-to-recover reserves. Enhanced oil recovery methods will help to resolve this issue.

There are the following enhanced oil recovery methods:

• gas;
• thermal;
• physical and chemical;
• group of combined methods;
• hydrodynamic and other methods.

As part of reservoir productivity enhancement, "Chemical Treatment of Wells" Business Unit (CTW BE) specializes in physical and chemical methods of oil recovery enhancement and renders the following services:

• Injection profile log conformance control;
• Polymer flooding;

And also supplies chemical reagents for recovery enhancement.

In addition, CTW BE is a leader in the field of log-inject-log field test.
