摘要： Aqueous well treatment fluid compositions with biocidal activity are disclosed comprising a polymer for modifying fluid viscosity in the aqueous fluid, an organic monocarboxylic peracid being present in an anti-microbial amount of about 1 ppm to about 1000 ppm, and a controlled amount of hydrogen peroxide also being present. Peracetic acid is the preferred peracid. The viscosity-modifying polymer in the aqueous well treatment fluid composition may serve to reduce friction in the fluid or increase fluid viscosity. A method of using such compositions is also disclosed.

摘要： Aqueous well treatment fluid compositions are disclosed comprising an aqueous fluid containing polymer or copolymer for modifying fluid viscosity of the aqueous fluid and, in addition, an agent for effecting a controlled reduction in the aqueous fluid viscosity in a subterranean environment. The viscosity-reducing agent comprises a dilute concentration of peracetic acid. A method of using such compositions in oil- and gas-field treatment operations is also disclosed.

摘要： A trailer for transporting a liquid mixture having at least about 5% peracetic acid by weight includes a stainless steel tank having an external spill containment enclosure and a predetermined maximum allowable working pressure. One or more pressure relief valves are included in a wall of the tank within the external spill containment enclosure and configured to provide pressure relief to the tank at a pressure of between about 20%-50% of the maximum working pressure of the tank, thereby preventing over-pressurization of a reactive and decomposing fluid during a fire event. Wheels and a kingpin are affixed to the tank to enable transportation over public roadways.
