... reductions. Background The industry has been changing to address the issues of proppant delivery, constantly striving to find better chemical products while pumping fewer of them. First, a general desire exists to move away from more-expensive chemical-derivative guar systems to simpler low-concentration...

... unexpected deviations from the design. A common mitigation measure is to adjust chemical concentrations, then adjust proppant concentrations, and then, as a last resort, change the pumping rate. While proppant and chemical changes can affect fluid-flow dynamics positively, their use also represents one...
