TL;DR: In this article, a well treating fluid useful in slickwater fracturing processes contains polyacrylamide friction reducer and a viscosity breaker capable of reducing the viscosities of the well-treating fluid to about the visco-conditions of water at ambient temperatures of typical underground formations.
Abstract: A well treating fluid useful in slickwater fracturing processes contains polyacrylamide friction reducer and a viscosity breaker capable of reducing the viscosity of the well treating fluid to about the viscosity of water at ambient temperatures of typical underground formations. The viscosity breaker is selected from the group consisting of hydrogen peroxide, calcium peroxide, magnesium peroxide, and zinc peroxide and is present in an amount above about 0.002% by weight.

TL;DR: A method for extracting vanadium using a perhydride sintered ore and slag is described in this paper, which has the advantages of simple equipment, little pollution and high extraction recovery.
Abstract: The invention discloses a method for extract vanadic using a perhydride sintered ore and slag. The method includes natrium peroxydatum, potassium superoxide, calcium dioxide, magnesium peroxide, zinc peroxide, alumina peroxide, barium peroxide or hydrogen dioxide as oxidant or solvent sintering or melting mineral and slag containing vanadium. The sintering process produces no harmful gases, Vanadium compound, vanadium, allegation with vanadium and steel products with vanadium is obtained through extraction. The invention has the advantages of simple equipment, little pollution and high extraction recovery, and is fit for extraction of vanadium from variouss ore and slag.
