Polymers and nanoparticles for flooding
A method and compounds for enhanced oil recovery (EOR) including flooding of a mixture of water and one or more of the compounds in a geological formation. The compounds have a fluoroalkyl group.
1. A method comprising:
pumping a mixture through a wellbore into a geological formation, the mixture comprising a surfactant, salt, water, and polymer nanoparticles having a fluoroalkyl group; and
flowing the mixture through the geological formation,
wherein:
the pumping and the flowing comprise enhanced oil recovery (EOR) comprising flooding:
the flooding of the geological formation increases oil recovery from a reservoir in the geological formation;
the flooding comprises nanofluid flooding,; and
the polymer nanoparticles having the fluoroalkyl group comprise polymers with the following polymeric structure:
where R1 is —CH2CF3, —CH(CF3)2, or —C(CF3)3, and where R2 is H or CH3.
2. The method of claim 1 , wherein the salt comprises sodium chloride.
3. The method of claim 1 , wherein the water comprises seawater or brine.
4. A method of enhanced oil recovery (EOR), comprising:
injecting a mixture through a wellbore into a geological formation, the mixture comprising water and polymer nanoparticles comprising a polymer having a fluoroalkyl group; and
flooding the geological formation with the mixture,
wherein the polymer nanoparticles has the following polymeric structure:
where R1 is —CH2CF3, —CH(CF3)2, or —C(CF3)3, and where R2 is H or CH3.
5. The method of claim 4 , wherein the flooding of the geological formation increases oil production of a well.
