A slick water fracturing fluid including a brine, an inorganic nitrate, a nitrogen reducing bacteria, a scale inhibitor selected from the group consisting of a polyacrylate polymer, a polyacrylate copolymer, a polyacrylate terpolymer, and mixtures thereof, and a friction reducer, wherein the friction reducer is a polyacrylamide.

Method for the use of nitrates and nitrate reducing bacteria in hydraulic fracturing

A method for scavenging hydrogen sulfide from geothermal steam in a condenser under vacuum. A fine curtain of atomized acrolein-water droplets may be sprayed into geothermal steam condensers in an amount of approximately 2:1 molar ratio of acrolein to HS based on hydrogen sulfide in the incoming steam from the turbine. The range being approximately 0.1 ppm to 500 ppm of sulfide. The acrolein is allowed to react with the gas phase HS to form non-volatile aldehyde byproducts which partition into the water phase, are returned to the cooling tower and ultimately removed by normal cooling-tower blow down.
