Enhanced Oil Recovery Market Worldwide Industry Analysis and New Market Opportunities Explored


Enhanced Oil Recovery, also known as tertiary oil recovery, is a set of techniques employed to extract further oil from reservoirs after primary and secondary methods of recovery have been exhausted. While primary recovery relies on natural reservoir pressure and secondary recovery involves injecting water or gas into the reservoir, EOR techniques go a step further by altering the properties of the oil or the reservoir itself to facilitate increased oil production.

EOR can potentially enhance well production and achieve up to 75% oil recovery. As a result, companies are increasingly investing in EOR to boost their oil and gas production. Given the extensive consumption of oil and gas, many companies are focused on expanding their production capacity. This involves upgrading existing wells, exploring new well sites, and expanding into new geographical regions.

Types of Enhance Oil Recovery
There are three main types of EOR: thermal EOR, chemical EOR, and gas EOR. However, not all wells and reservoirs are suitable for EOR due to the associated costs and the quantity of hydrocarbons extracted. Each field must undergo a thorough evaluation to determine the most effective type of EOR. This evaluation process involves reservoir characterization, screening, scoping, and reservoir modeling and simulation.

Thermal EOR
Thermal recovery is one widely utilized technique within EOR. It involves introducing heat to the reservoir to reduce the viscosity of the oil, making it easier to flow. Steam injection is a common method employed in thermal recovery, particularly for extracting heavy viscous crude oil. By applying steam to the reservoir, the oil is thinned, enhancing its mobility and facilitating improved flow rates.

Steam flooding, steam-assisted gravity drainage, and cyclic steam stimulation are some of the common steam injection methods utilized. Steam flooding is suitable for light-oil reservoirs with depths of less than 3,000 feet, while in-situ methods are generally employed for heavy-oil sandstone reservoirs.

Chemical EOR
Chemical EOR methods employ the use of chemicals to alter the properties of the oil or the reservoir, enhancing oil recovery. One common technique is polymer flooding, where water-soluble polymers are injected into the reservoir to increase the viscosity of the injected water, displacing more oil. Surfactant flooding and alkaline flooding are other chemical EOR methods that help improve oil displacement and reduce interfacial tension
