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.

Polymers and nanoparticles for flooding

Methods and systems including introducing a treatment fluid into a subterranean formation wellbore. The treatment fluid includes an aqueous base fluid; nitrogen-containing waste plastic; and carbon dioxide. The nitrogen-containing waste plastic is hydrolyzed in the aqueous base fluid under conditions in the subterranean formation wellbore, thereby forming hydrolysis reaction products. The hydrolysis reaction products and the carbon dioxide are reacted in the subterranean formation wellbore.

Methods of hydrolyzing nitrogen-containing waste plastics downgole to form a solid barrier

A system and method for flow synthesis of polymer nanoparticles in a continuous flow reactor having a channel. The polymer nanoparticles are synthesized from monomer in the presence of an initiator.

Flow synthesis of polymer nanoparticles

Degradable polymer additives are provided. The degradable polymer additives include a tracer functional group that is bonded to a base polymeric component by a hydrolysable covalent bond. The base polymeric component is a polysaccharide. The tracer functional group is selected from the group comprising a halogen-containing functional group, a substituted heterocyclic aromatic group, and combination thereof. A method utilizing the degradable polymeric additives in an altered drilling fluid is provided. Such a method includes introducing the altered drilling fluid into a wellbore and recovering an associated wellbore cutting from a depleted drilling fluid.

Degradable tags for depth correlation mud logging

A method of surface logging a well includes adding each of multiple polymeric taggants to a circulating drilling fluid in an addition sequence while drilling the well. Each polymeric taggant includes a polymer and a respective fluorescent dye having an emission wavelength or excitation wavelength different from that of each other fluorescent dye. The method includes taking a sample of drill cuttings carried by a drilling fluid while drilling a well, wherein the sample of drill cuttings includes polymeric taggants attached to the drill cuttings. The method includes extracting the dyes from the sample of drill cuttings into an extract solution; determining an indication of the type of and the concentration of each of the dyes in the extract solution; and determining a depth associated with the sample of drill cuttings based on the indication of the concentration of each of the dyes and on the addition sequence.
