Abstract: Embodiments of the present disclosure are directed to a method of producing a viscoelastic surfactant (VES) fluid, the VES fluid comprising desulfated seawater. The method of producing the VES fluid comprises adding an alkaline earth metal halide to seawater to produce a sulfate precipitate. The method further comprises removing the sulfate precipitate to produce the desulfated water. The method further comprises adding a VES and one or more of a nanoparticle viscosity modifier or a polymeric modifier to the desulfated seawater. Other embodiments are directed to VES fluids that maintain a viscosity greater than 10 cP at temperatures above 250° F.

Abstract: A method for using an accelerated solvent extractor to study ion reaction parameters is provided. The method includes entering a solution mixture and reaction parameters for each of a plurality of extraction cells, wherein the solution mixture includes a ratio of a first ion solution to a second ion solution. The solution mixture is reacted in each of the plurality of extraction cells at the reaction parameters for that extraction cell. Effluent and solids are collected from each of the plurality of extraction cells. The effluent and the solids are analyzed to obtain composition results. The composition results are correlated to the solution mixture for each of the plurality of extraction cells and the reaction parameters for each of the plurality of extraction cells.

Abstract: Treating carbon steel tubing includes contacting the carbon steel tubing with a first treatment solution including a salt; corroding the carbon steel tubing with the salt to yield a corroded surface on the carbon steel tubing; contacting the corroded surface on the carbon steel tubing with a second treatment solution comprising sulfide ions; and forming an iron sulfide layer on the corroded surface of the carbon steel tubing by chemically bonding the sulfide ions in the second treatment solution with iron in the carbon steel tubing. In some cases, the first treatment solution also includes sulfide ions, and the iron sulfide layer is formed by contacting the carbon steel tubing with the first treatment solution.

Abstract: A system and a method for implementing a squeeze treatment to apply a scale inhibitor in a wellbore are provided. An exemplary method includes mixing a scale inhibitor pill. The scale inhibitor pill includes polyamino polyether methylene phosphonic acid (PAPEMP) and amino trimethylene phosphonic acid (ATMP). Pre-flush chemicals are injected into the wellbore. The scale inhibitor pill is injected into the wellbore. An over flush is injected into the wellbore. The wellbore is shut in for a target period of time and normal production is resumed.
