摘要： An injection fluid composition includes a treatment agent and a carrier fluid. The treatment agent includes a material having a reactive surface functionality. The material having a reactive surface functionality is selected from the group consisting of graphite, graphene, activated carbon, and combinations thereof. Additionally, a method of treating a sludge in production tubing is presented. The method includes injecting a first fluid including a treatment agent in a carrier fluid into the production tubing, contacting the sludge with the treatment agent, maintaining the first fluid downhole such that the treatment agent adheres on a surface of the sludge, injecting a second fluid comprising a stimulating agent to stimulate the treatment agent, and extracting compounds of the sludge from the production tubing.

摘要： Methods for making a low-density gel or composite in a wellbore are provided. An exemplary method includes injecting a sealer component including a low-density material into the wellbore, allowing the sealer component to float to the top of an oil column, injecting an activator component including another low-density material into the wellbore, allowing the activator component to float to the top of the oil column and contact the sealer component, and contacting the sealer component and the activator component to form a gel.

摘要： A surface-modified activated carbon includes activated carbon, a plurality of sulfonate groups, and a plurality of metal atoms. The sulfonate groups are chemically bonded to the activated carbon, and the metal atoms are independently chemically bonded to the sulfonate groups. The surface-modified activated carbon has a net positive charge. A method for producing a surface-modified activated carbon includes mixing activated carbon with a sulfur-containing compound including sulfonate groups, chemically bonding the sulfonate groups the activated carbon to produce sulfonated activated carbon, combining the sulfonated activated carbon with a solution containing metal atoms, and chemically bonding the metal atoms to the sulfonate group. A method for removing an impurity in a subterranean well includes introducing a surface-modified activated carbon into the subterranean well containing a produced water containing an impurity, contacting the impurity with the surface-modified activated carbon, and adsorbing the impurity with the surface-modified activated carbon.

摘要： A well system includes a well extending from a surface into a formation, a Y-tool provided at an end of a tubing string extending through the well, a concentric coiled tubing string extending through the tubing string and through a bypass line of the Y-tool, and a plurality of treatment solutions provided at the surface of the well. The plurality of treatment solutions includes at least one component of a dissolvable gel, a gel dissolving solution, and at least one component of a non-dissolvable gel. A method for plugging a water zone in a hydrocarbon bearing formation and a method for reducing a concentration of produced water from a hydrocarbon bearing formation are also described.
