Abstract: A hydraulic fracturing method is disclosed. A small proportion of a nonionic surfactant is used in combination with an acrylamide polymer emulsion friction reducer, the proppant, and the base water to boost the viscosity of the fracturing fluid. The nonionic surfactant has a calculated HLB within the range of 10 to 17. The nonionic surfactants include selected aralkylated phenol ethoxylates, amine or amidoamine ethoxylates, mixed EO/PO alcohol alkoxylates, ethoxylated alcohols, ethoxylated amides, and alkylphenol ethoxylates. The nonionic surfactant boosts the viscosity of the fracturing fluid, promotes proppant transfer, and enables more-efficient hydrocarbon production.

Abstract: A method of killing insects on or around an intact plant, comprising the step of depositing or suspending in the air a composition comprising synthetic amorphous silica (SAS) on or around the intact plant.

Abstract: A method of killing insects on or around stored products or in structures, comprising the step of depositing or suspending in the air a composition comprising a mixture of hydrophilic synthetic amorphous silica (SAS) and hydrophobic SAS on or around the stored products or structure.
