Patent number: 11028309Abstract: A cement slurry may be separated from a drilling mud in a wellbore by introducing into the wellbore an aqueous fluid having a weighting agent, a hydratable gellant powder having a particle size distribution from about 150 to about 300 mesh; and a suspension agent of particulates of a resin encapsulated hydratable polymeric viscosifying agent, the suspension agent having a particle size distribution such that at least 90% of the particulates are retained on a 20 mesh screen and 100% of the particulates are retained on a 6 mesh screen. The weighting agent may be suspended in the viscous fluid by hydrating the hydratable gellant powder. At higher temperatures and after degradation of the hydrated gellant, the weighting agent remains suspended by degrading the resin of the suspension agent and releasing the hydratable polymeric viscosifying agent into the wellbore.Type: GrantFiled: February 8, 2019Date of Patent: June 8, 2021Assignee: Baker Hughes Oilfield Operations LLCInventors: Angela Anh Doan, Matthew Grady Kellum, Shailesh Shashank Dighe, Andrew Christopher Holley

Patent number: 7066996Abstract: A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a ready mixed joint compound composition wherein the amount of the cellulose ether in the joint compound composition is significantly reduced. When this joint compound composition is mixed with water and applied to a substrate, the water retention, sag resistance, and workability of the wet joint compound are comparable or improved as compared to when using conventional similar cellulose ethers.Type: GrantFiled: April 25, 2005Date of Patent: June 27, 2006Assignee: Hercules IncorporatedInventor: Thomas J. Podlas
