A method to determine the velocity of static proppant settling in fracturing fluids. The proppant carrying capability of different friction reducer products can be compared, so the appropriate friction reducer product can be selected for hydraulic fracturing operations. The effect of friction reducer concentrations in the fracturing fluids, the salinity and hardness of the fracturing fluids, and the proppant size on the velocity of static proppant settling can be studied to optimize the chemical structures of the friction reducers in the process of synthesis and optimize the hydraulic fracturing operation, e.g. to determine the proper concentration of friction reducers according to the salinity and proppant size.

Apparatus and method for determining the static proppant-settling-velocity in fracturing fluids

Nano- and micro-particles (NMP) can be formed from an oil/water emulsion. The emulsion is made by mixing a liquid solvent, at least one surfactant, a particle-forming compound, and at least curing agent. If desired, pH control agents and viscosity enhancers can be added to the liquid solvent. The particle-forming compound and the curing agents are mixed together and form the oil phase in the emulsion and after curing, the particles are formed. The nano- and micro-particles can be used as proppant to enhance the conductivity of nano- and microfractures and fluid-loss-control additive for hydraulic fracturing operations.

A hydraulic fracture fluid is provided. The fluid can include a liquid solvent, one or more surfactants, a proppant-forming compound, and one or more curing agents. The liquid reacts to form proppant in-situ under downhole conditions.

Method of hydraulic fracturing utilizing a hydraulic fracturing fluid with a single phase liquid proppant

A novel surfactant composition that comprises of two surfactant components, a solvent, and water. The surfactant composition is added to a fracturing fluid, which is then pumped downhole into a subterranean formation where the novel characteristics of the fracturing fluid lend to improved oil production over the fracturing fluid without the surfactant composition.

A polyacrylamide friction reducer wherein the friction reducer contains surfactant functional groups, and wherein the polyacrylamide friction reducer is degradable, can be used for multi-functional, slickwater fracturing fluid projects. Under downhole conditions, the polymer degrades and releases the surfactant molecules to act as oil displacing agent to provide additional stimulation.

Degradable friction reducer for hydraulic fracturing treatments

The disclosed hydraulic fracturing fluid can include a liquid solvent, one or more surfactants, a proppant-forming compound, and one or more curing agents. When injected into a wellbore, the hydraulic fracturing fluid reacts to form proppant pillars in-situ under downhole conditions. The proppant pillars are capable of maintaining conductive fractures.

A method for forming rod-shaped particles includes reducing a length of rods derived from a slurry made up of particles and a reactant, wherein the rods are in a stabilized state in which the reactant has been at least partially reacted with a coagulant, but the rods have not been sintered, and subsequently sintering the reduced length stabilized rods. The reducing the length of the stabilized rods includes subjecting the stabilized rods to mechanical vibration applied by a device, or feeding the stabilized rods through a device having a rotating cutting mechanism.
