Patent number: 10258986Abstract: 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.Type: GrantFiled: November 9, 2015Date of Patent: April 16, 2019Assignee: University of New HampshireInventors: Brian G.

Patent number: 8119574Abstract: A slurry and method are disclosed for low damage gravel packing. The slurry comprises a solids mixture comprising a plurality of volume-averaged particle size distribution (PSD) modes such that a packed volume fraction (PVF) exceeds 0.75; a carrier fluid in an amount to provide a solids volume fraction (SVF) less than the PVF of the solids mixture; and a stability additive to inhibit settling of the solids mixture. The method comprises circulating the slurry into a wellbore to deposit the slurry downhole; terminating the slurry circulation for a period of time, wherein the stability additive inhibits settling of the solids mixture; and thereafter circulating the deposited slurry in contact with a surface of a screen. Stability additives disclosed include colloidal particles, hydratable polymer particles, and particles having an aspect ratio above 6.Type: GrantFiled: June 30, 2010Date of Patent: February 21, 2012Assignee: Schlumberger Technology CorporationInventors: Mohan K.

Patent number: 8114602Abstract: A method and assay are described for measuring the interaction between a ligand and an analyte. The assay can include a suspension of colloidal particles that are associated with a ligand of interest. The colloidal particles are maintained in the suspension at or near a phase transition state from a condensed phase to a dispersed phase. An analyte to be tested is then added to the suspension. If the analyte binds to the ligand, a phase change occurs to indicate that the binding was successful.Type: GrantFiled: December 6, 2004Date of Patent: February 14, 2012Assignee: The Regents of the University of CaliforniaInventors: John T. Groves, Michael M. Baksh, Michal Jaros

Patent number: 8053394Abstract: A drilling fluid has a redispersible polymer powder introduced as a water dispersion that is capable of providing a deformable latex film on at least a portion of a subterranean sand formation and which inhibits or controls fluid loss and acts as a sealing agent when used to drill in sand formations for hydrocarbon recovery operations. The redispersible polymer powder may be made by drying the emulsion in which they are formed and then grinding into a powder or by spray drying. The polymer particles of suitable size precipitate or collect or assemble onto the pores of a subterranean sand formation to at least partial seal the formation with a deformable polymer film.Type: GrantFiled: February 18, 2010Date of Patent: November 8, 2011Assignee: Baker Hughes IncorporatedInventors: Tao Xiang, Dennis K. Clapper, Donald C. Krause
