Chemical flooding enhanced oil recovery

Summary. The Chemical Enhanced Oil Recovery (EOR) Research Project includes both experimental and modeling research and development of all chemical EOR methods including polymer flooding, surfactant flooding, alkaline-surfactant-polymer flooding, wettability alteration, mobility control using foam and low salinity water flooding by a team of more than 50 faculty members, senior research It involves any reservoir process that is used to change the existing rock/oil/brine interactions in the reservoir, including thermal recovery, miscible flooding, microbial, and chemical flooding. Chemical flooding methods might include polymer, deep-formation profile control using gels, surfactant, alkaline, emulsion, foam, and their combinations. Delshad has more than 20 years of work experience in chemical flooding. She has worked extensively on the development and application of reservoir simulators for enhanced oil recovery processes, and is currently in charge of development and user support for the University of Texas’ chemical flooding oil reservoir simulator.

Surfactant flooding has the potential to significantly increase recovery over that of UTCHEM is a reservoir simulator specially designed for surfactant EOR. 27 Nov 2015 Typical EOR mechanisms include chemical flooding, gas injection and with some chemicals (surfactants and polymers) to enhance the oil  Chemical techniques account for about one percent of U.S. EOR production. flood design to deliver CO2 to un-swept areas of a reservoir, and improved  Alkaline-Surfactant-Polymer (ASP) flooding is an efficient method but was poorly applied in the industry as it is costly. The best mixture and injection sequence is 

The chemical solutions are pumped through specially distributed injection wells to mobilize oil left behind after primary or secondary recovery. Chemical flooding is a major component of enhanced oil recovery processes and can be subdivided into micellar-polymer flooding and alkaline flooding.

Enhanced Oil Recovery Polymer flooding is the most widely used Chemical Enhanced Oil Recovery (CEOR) method. It is relatively simple to apply and has a long history of successful field applications. Field implementation requires specialized mixing and injection equipment to avoid polymer degradation and viscosity loss. A review on chemical flooding methods applied in enhanced oil recovery Article (PDF Available) · January 2008 with 3,457 Reads How we measure 'reads' Enhanced Hydrocarbon Recovery. Primary oil and gas recovery methods unlock only about 10% of the oil initially in place (OIIP), while secondary recovery efforts obtain an additional 20 – 40%. Therefore, a substantial quantity of oil remains in the formation until more advanced recovery methods are employed. A chemical enhanced oil recovery flood that uses two sources of surfactant and a polymer. Alkaline chemicals such as sodium carbonate react with acidic oil components in situ to create petroleum soap, which is one of the surfactants. A synthetic surfactant is injected simultaneously with the alkali.

investigate this issue that Smart water will change wettability and surfactant will decrease Smart water or water flooding is an interesting solution in oil and gas field, In Enhance Oil Recovery (EOR) the main goal is to increase oil extraction  

That leaves chemically enhanced oil recovery (CEOR) on the short list of CEOR in the 1970s and 1980s focused on "micellar" flooding with 2-12% surfactant.

Chemical EOR is implemented in stages and actual size/duration of each stage depends on economics. Typical chemical flood incremental recovery is in the 

Chemical flooding for enhanced oil recovery involves the use of surfactants which reduce the interfacial tension for the mobilization of trapped oil; polymers  The Vinci CHEMFLOOD warrants various chemical flooding experiments including polymer flooding, Alkaline-Surfactant flooding and foam injection. These tertiary  Chemical EOR is implemented in stages and actual size/duration of each stage depends on economics. Typical chemical flood incremental recovery is in the  Chemical EOR. Chemical flooding was, up to 2000s, a less common EOR method than thermal and gas flooding, but now, huge projects are retrieved. The
