  • Method for control of fluid loss and gas migration in well cementing
    Patent number: 6136935
    Abstract: This invention discloses a composition and a method of using the composition to cement a borehole penetrating a subsurface earth formation. The composition, the random polymerization product of two or three different vinyl-containing monomers including a vinylamide morpholine derivative, operates to reduce fluid loss from the cement slurry used to cement the borehole to the subsurface formation.
    Type: Grant
    Filed: August 12, 1999
    Date of Patent: October 24, 2000
    Assignee: Fritz Industries, Inc.
    Inventors: Rebecca G. Udarbe, Kim Hancock-Grossi
  • Method of and additive for controlling fluid loss from a drilling fluid
    Patent number: 6107256
    Abstract: This invention provides a composition for and a method of using the composition to reduce the loss of liquid from aqueous compositions employed while rotary drilling. The composition of this invention comprises a polymeric material selected from homopolymers, random copolymers and random terpolymers, each of which includes a vinylamide morpholine derivative in the recipe for making the polymeric material.
