Enhanced recovery
Technology and partnerships remain important, while phased approaches may supplant lengthy appraisal programs, experts said during CERAWeek.
This paper introduces a novel steam-sensitive flow-control device designed to restrict the production of steam and low-subcool liquids while allowing higher mobility of oil-phase fluids.
This paper describes the operator’s initiative to reduce greenhouse-gas emissions and recover additional hydrocarbon, monetizing it as sales gas, by integrating upstream and downstream gas facilities in a unified approach.

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. -
Water handling is becoming increasingly important as a technical and economic tool for improved oil recovery and enhanced oil recovery (EOR) projects. A global series of workshops to address these issues has been planned.
-
In this paper, the authors report results from experiments as well as modeling of water/oil-emulsion rheology that can form during alkaline/surfactant/polymer injections for enhanced recovery.

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.
