摘要： Solid surfactant suspension compositions are formed by combining solid surfactants, such as alpha-olefin sulfonates, with an organic base fluid, such as diesel. Solid surfactant suspensions may be combined with an aqueous carrier fluid to form surfactant-containing fluids suitable for, among other things, forming foams or for water wetting surfaces. Solid surfactant suspensions may also be combined with additive materials, such as polymer particles, to form a dispersion or emulsion. Polymer-containing solid surfactant suspensions may also be combined with aqueous carrier fluids to form, for example, viscosified, gelled, or foamed fluids. Concentration of solid surfactant materials contained in a solid surfactant suspension may be varied to affect the function the solid surfactant suspension. For example, the solid surfactant material may function as a polymer surface wetting agent, an emulsifier, a dispersant, a viscosifier, and/or a foamer in well completion and remedial and/or workover fluids.

摘要： A method is shown for fracturing a subterranean formation in which a hydratable polymer, crosslinking agent and breaker are combined in an aqueous carrier to form a gelled fracturing fluid. The breaker is comprised of a substantially insoluble oxidant which is granulated and formed into a pellet or prill with a suitable binder. The pellet so formed can also contain a chelating agent and an activator in order to enhance the rate of breaking. The substantially insoluble oxidant is selected from the group consisting of alkaline earth and zinc salts of peroxide, perphosphate, perborate, and percarbonate.

摘要： An oil and gas well cementing composition and method is shown utilizing hydraulic cement, water and an additive having pendant phosphonate groups on a polymeric backbone. The additive provides improved fluid loss and settling characteristics while maintaining desirable viscosity and setting time characteristics. Pendant phosphonate groups are added to the polymer by adding about 0.2% to about 10.0% by weight phosphonic acid either during or after polymerization.

摘要： Viscoelastic surfactant (VES) gelled aqueous fluids containing water, a VES, an internal breaker, a VES stabilizer, a fluid loss control agent and a viscosity enhancer are useful as treating fluids and particularly as fracturing fluids for subterranean formations. These VES-based fluids have faster and more complete clean-up than polymer-based fracturing fluids. The use of an internal breaker permits ready removal of the unique VES micelle based pseudo-filter cake with several advantages including reducing the typical VES loading and total fluid volume since more VES fluid stays within the fracture, generating a more optimum fracture geometry for enhanced reservoir productivity, and treating reservoirs with permeability above the present VES limit of approximately 400 md to at least 2000 md.

摘要： A method for increasing the stability of water-based fracturing fluids is shown in which a base fracturing fluid is formulated by mixing together a hard mix water containing multivalent cations, a water soluble polymer and a cross-linking agent for the water soluble polymer. A water softener is added to the base fracturing fluid which hinders the ability of the multivalent cations present in the hard mix water to compete with the water soluble polymer for borate based cross-linking agent, thereby stabilizing the resulting fracturing fluid.

摘要： A crop sheild is connected to the aft ends of a pair of parallel links by a bracket assembly which can pivot to permit the shield to dump trash. The bracket assembly is pivotally connected to the aft end of the lower link and includes a slot slidably received on a pin located on the aft end of the upper link to maintain the links in a generally parallel relationship. The weight of the shield normally biases the shield to a horizontal field-working position with the end of the slot stopped against the pin. When trash builds up, the shield pivots with respect to the lower link and the slot slides over the pin as the shield moves up against the bias over the trash. Dump forces are reduced since the shields pivot independently of the parallel links.
