A multipurpose enhanced oil recovery (EOR) rig developed at the Petroleum and studies of different recovery methods associated with chemical, thermal and
For many of oil fields, particularly where low-to-medium gravity oils are found or where the oil viscosity is unfavourable for conventional EOR methods application, Thermal Recovery Methods are the best techniques for ultimate recovery. Vast deposits of heavy oil exist in Canada, Venezuela and USA that are amenable to recovery by Thermal Recovery. Thermal Recovery is usually applied to heavy to medium oils, however these methods can be applied to any field being considered and be competitive Thermal Recovery. Thermal recovery introduces heat to the reservoir to reduce the viscosity of the oil. Many times, steam is applied to the reservoir, thinning the oil and enhancing its ability to flow. First applied in Venezuela in the 1960s, thermal recovery now accounts for more than 50% of applied EOR in the US. Tertiary (EOR) recovery methods. Tertiary is also referred to as EOR (enhanced oil recovery) which is accomplished via thermal and non-thermal means. When heavy oil reaches a certain weight, and secondary methods fail, non-thermal or thermal tertiary methods are employed. Non-thermal methods include microbial and CO2 flooding. But heat—primarily via steamflooding—is the most favored and effective method of inducing more oil to flow. Steam is injected into the injector well to help Thermal Recovery Processes. The recovery processes of oil are increased due to dependency of the industry to them and the requirements to petrochemical products. This leads to oil extraction from unconventional reservoirs to compensate the possible deficiency between production and demand, and oil with low API gravity. Primary and secondary methods of oil recovery are mainly used to recover the lighter, less viscous crude oil. Thermal enhanced oil recovery is popular method of extracting the harder-to-obtain heavy crude oil. But enhanced oil recovery (EOR) technologies aim to recover billions of barrels already discovered, yet historically beyond reach. With such huge potential, Chevron invests time, money and talent to continuously improve steamflooding (new horizontal wells in California, for example, yield 10 times more oil than conventional wells).

There are basically three enhanced oil recovery methods which involve thermal, chemical and gas use. By using these techniques, an oil field can be stimulated These processes may include pressure maintenance, injection of displacing fluids, or other methods such as thermal techniques. Therefore, by definition, EOR Thermal enhanced oil recovery techniques Oil & Gas Engineering spoke with Dr. Berna Hascakir from the Heavy Oils, Oil Shales, Oil Sands, and Carbonate Recovery Methods (HOCAM) center at Texas A&M University to get a glimpse of new technologies being developed to extract heavy oil and bitumen in unconventional plays. Thermal recovery, which involves the introduction of heat such as the injection of steam to lower the viscosity, or thin, the heavy viscous oil, and improve its ability to flow through the reservoir. Thermal techniques account for over 40 percent of U.S. EOR production, primarily in California. Enhanced oil recovery, also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, there are three primary techniques for EOR: thermal, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery.
