  • Patent number: 10258986
    Abstract: Techniques are disclosed for producing a drop of a viscoelastic fluid. A separation volume of viscoelastic fluid that is to form a drop from a larger remnant volume of viscoelastic fluid is moved from through an interface and into a cross-channel. Movement subjects the viscoelastic fluid to shear that may cause a reduction in viscosity. Movement of the viscoelastic fluid is then reduced or stopped (i.e., the rate at which shear is applied is reduced), such that the viscosity of the viscoelastic fluid may increase as the viscoelastic fluid experiences relaxation. The separation volume of viscoelastic fluid is then moved down the cross-channel in a first direction by the flow of an immiscible fluid, which separates the separation volume from a remnant volume. The separation volume may then be dispensed from the cross-channel as a drop.

  • Patent number: 7833950
    Abstract: A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are given that have properties optimized for proppant transport but degrade after the treatment into degradation products that do not precipitate in the presence of ions in the water such as calcium and magnesium. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers.

  • Patent number: 7776928
    Abstract: Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a solids content up to about 45% solids. The emulsions are stable, and are characterized by having an average particle size less than 1000 nanometers. When used to coat fibrous cellulosic articles, such as paperboard, the emulsions' performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-200 degrees F. (49-94 degrees C.) (Mettler Drop Point). The inventive waxes are used as an alternative to petroleum-derived, or expensive naturally-occurring waxes in the manufacture of emulsions used in coatings, polishes, adhesives, paper products, paperboard and other manufacturing operations.
