Description

Foam injection is an attractive EOR scheme in terms of cost, effectiveness, and environmental-friendliness. Foams mainly serve as mobility control or gas blocking agents. To optimize their effectiveness, the critical foam parameters should be studied at reservoir-representative conditions. The FOAMEVAL permits this; foams are produced in a high pressure visual cell continuously monitored by a high-resolution image capturing system. A dedicated Vinci software then interprets the images and reports the following:

Physical quantities measured in Real Time:

* Gas flowrate
* Volume of the foam
* Volume of liquid in foam

Physical quantities calculated in Real Time:

* Volume of the foam
* density of the foam
* Bikerman index
* Foam stability
* Foam expansion coefficient
* Foaming capability
