Tertiary (enhanced) techniques prolong the life of producing fields, ultimately leading to recovery of 30 to 60 percent of the original oil in place. Many of the existing and proposed enhanced oil recovery techniques require sound understanding of basic chemical engineering principles such as fluid flow, heat and mass transfer, interfacial phenomena etc. Adi Junira. The methods of enhancing recovery of heavy crude oil explore the importance of enhanced oil recovery and how it has grown in recent years due to the increased needs to locate unconventional resources such as heavy oil, shale, and bitumen. Nikolai A. Eremin, Larisa N. Nazarova. Enhanced oil recovery can be broken down into two categories – secondary recovery and tertiary recovery. Research in our Section includes chemical EOR including polymers and surfactants, thermal methods, and sweep efficiency in gas injection, with a particular focus on foam for improved sweep efficiency in gas injection. Enhanced Oil Recovery - EOR: Enhanced oil recovery (EOR) is the process of obtaining stranded oil not recovered from an oil reservoir through certain extraction processes. Enhanced Oil Recovery Field application data shows that the new NAG HnP treatment produces significant and sustained improved hydrocarbon recovery. Bottom hole pressures exceeding 1000 pounds per square inch have been generated in this manner, actually forcing oil to flow from a depth of 5000 feet, or creating gas pressure in offset wells 1/2 mile away.When used in the field to stimulate depleted or slowly producing wells, the process has been highly cost effective, compared to the most economical of the other enhanced recovery technologies. The use of CO 2 in enhanced oil recovery had proven to be a technical and economic success for more than 40 years, but the same had not been applied for enhanced gas recovery and storage . In its initial applications, the technology was used to treat open-hole completed horizontal wells in the Austin Chalk and Buda Limestone with a combination of N 2 and nanoparticles.
