Biocide compositions comprising biocide, surfactant, and solubilizing agent. The preferred biocide is parachlorometaxylenol. The biocide composition is useful in oil and gas drilling operations, such as hydraulic fracturing, as well as treating aqueous slurries in ore mining operations. The biocide compositions are effective in controlling microorganisms even in the presence of high salt content water and at high temperatures. |
