Terradyne also provides Enhanced Oil Recovery (EOR) solutions to clients. It is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field. Enhanced oil recovery can also be referred to as tertiary recovery.Although it is an important energy resource, heavy oil requires an unusually high level of effort and expertise to economically develop and produce. Production rates of this high viscosity, often chemically compromised hydrocarbon are influenced by both the effectiveness of available technology and the supply and affordability of conventional oil. But as energy demands grow, major conventional oil discoveries are rare (and difficult to find) and the costs of discovering and producing conventional oil goes up, the economics of heavy oil will steadily improve.
