Chichimene is an oil field in eastern Colombia. Since 2014, enhanced oil recovery (EOR) using a water-injection process has been performed successfully in part of this field. A polymer-injection pilot was executed over five injection patterns to optimize this process as a promising strategy for polymer-based EOR in challenging reservoir conditions with high temperatures and heavy oil.
Field Background
Included in Colombia’s energy-transition strategy are EOR technologies that, through the acceleration of oil production even with low energy consumption, increase the efficiency and carbon intensity of conventional oil-production processes. Several studies in the literature have reported improved energy and carbon indicators as a result of implementing EOR using thermal and chemical methods.
