  • Compositions for delayed acid generation for high temperature applications and methods of making and using same
    Patent number: 11414590
    Abstract: A method of servicing a wellbore penetrating a subterranean formation, comprising placing into the wellbore a wellbore servicing fluid comprising a sterically-hindered ester having a general formula R1COOR2 and an aqueous fluid, wherein R1, R2 or both have A-values greater than about 1.76 kcal/mol.
    Type: Grant

  • Lost Circulation Pill for Severe Losses using Viscoelastic Surfactant Technology
    Publication number: 20190367800
    Abstract: A lost circulation composition includes at least one viscoelastic surfactant that can self-assemble into entangled worm-like micellar structures, increasing the viscosity of the composition at low shear rates. The entanglements of the worm micelles can be reduced at high shear rates, but can be regenerated when the shear rates are reduced. The viscosifying micelle behavior is present at temperatures above 100° C. and regardless of salinity.

  • Curauá fibers as lost-circulation materials and fluid-loss additives in wellbore fluids
    Patent number: 9963628
    Abstract: A method and wellbore fluid using Curaua fiber to prevent or cure loss circulation during well operations. The wellbore fluid includes a base fluid and a plurality of Curaua fibers. The wellbore fluid may include concentration up to 120 lb/bbl Curaua fibers. The base fluid may include at least one of water-based fluid, brine-based fluid, oil-based fluid, synthetic-based fluid, or Pneumatic-drilling fluid system. The water-based fluids may further include at least one of seawater, brine, saturated brine, or formate brine. The water-based fluid may include a dispersed system. The water-based fluid may further include a non-dispersed system. The oil-based fluid may include at least one of diesel, mineral oil, and low-toxicity linear olefins and paraffins. The synthetic-based fluid may include at least one of one of esters, internal olefins and linear paraffins. The oil-based and the synthetic-based fluids may further include lime.
