The oil & gas industry continues to be a hotbed of patent innovation. Activity is driven by the need to maximize crude oil recovery from existing oilfields, optimize capital spend and achieve emissions reduction across the company portfolio. Therefore, the industry is pursuing decarbonization, and hence, there has been a growing interest in technologies such as carbon capture utilization and storage (CCUS) to support the carbon dioxide (CO2) induced enhanced oil recovery operations. In the last three years alone, there have been over 327,000 patents filed and granted in the oil & gas industry, according to GlobalData’s report on Environmental sustainability in oil & gas: oil recovery CWI.

According to GlobalData’s Technology Foresights, which uses over 201,000 patents to analyze innovation intensity for the oil & gas industry, there are 65+ innovation areas that will shape the future of the industry.
Oil recovery CWI is a key innovation area in environmental sustainability
Carbonated water injection (CWI) is an innovative technique used in the secondary and tertiary phases of oil recovery. In this technique, CO2 dissolved in water is injected into the oil reservoir from an injection well, to sufficiently mobilize oil flow at the production well. As oilfields deplete over time, the CWI technique can help oil and gas companies to increase the oil recovery from such wells, thereby extending their production life. Thus, companies can generate higher return from their hydrocarbon assets. It could also help companies conserve their capital that would have otherwise been spent on bringing additional fields online.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies.
According to GlobalData, there are 125+ companies, spanning technology vendors, established oil & gas companies, and up-and-coming start-ups engaged in the development and application of oil recovery CWI.
Key players in oil recovery CWI – a disruptive innovation in the oil & gas industry

Equinor is the leading patent filers in CWI for oil recovery in the oil & gas industry. Equinor has several aging oilfields in the North Sea. It is also a major promoter of carbon capture technologies and is part of the Northern Light carbon capture project in Europe. Equinor is best placed to exploit captured carbon for tertiary oil recovery applications. Equinor can exploit this situation as part of its compact CO2 capture and carbonated water injection or 3CWITM concept. Some other key patent filers in the oil and gas industry include Schlumberger, Exxon Mobil, Halliburton, China Petrochemical, China National Petroleum, and Saudi Arabian Oil.
Equinor, Saudi Arabian Oil and Doosan are among the leaders in terms of application diversity. Doosan has a wide range of product and service portfolio for diverse industries, which includes the energy sector. It offers technology and EPC services to the oil and gas companies.
By means of geographic reach, PALMER LABS held the top position, followed by Tokyo Gas and Mitsubishi Heavy Industries. PALMER LABS is a clean energy technology developer in themes that have positive environmental impact.
CWI technique enhances the lifetime of ageing fields and also act as a dumping method for carbon captured from industrial operations. Growing CCS adoption can in-term be mutually beneficial for tertiary oil recovery from producing assets using CWI method.
