Hydraulic fracturing of chemicals are used per fracturing. A typical fracture treatment uses between 3 and 12 additive chemicals. Although there may be unconventional fracturing fluids, typical chemical additives can include one or more of the following: The most common chemical used for hydraulic fracturing in the United States in 2005–2009 was methanol, while some other most widely used chemicals were isopropyl alcohol, 2-butoxyethanol, and ethylene glycol. Typical fluid types are: For slickwater fluids the use of sweeps is common. Sweeps are temporary reductions in the proppant concentration, which help ensure that the well is not overwhelmed with proppant. As the fracturing
Foam latex actor Akim Tamiroff. To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure. The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked). A number of additional additives can also be added depending on the required use of the foam. Foam latex
