polymer flooding

A successful pilot test of polymer flooding was conducted in the San Jorge Gulf basin.

Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.

The Polymer injection project on the Dalia field, a high permeability sandstone reservoir deep offshore Angola, is a world first in both surface and subsurface aspects. A phased approach was used to manage risks, along with development of new monitoring approaches.
