  • Degradable particulates as friction reducers for the flow of solid particulates and associated methods of use
    Patent number: 7608566
    Abstract: Particulate compositions that comprise macro-particulates, and degradable particulates in an amount sufficient to reduce friction between the macro-particulates, the degradable particulates having a mean particle diameter of at least about 20 times smaller than the mean particle diameter of the macro-particulates are disclosed herein. Also disclosed are fluids that comprise a liquid component, and a particulate composition, the particulate composition comprising macro-particulates and degradable particulates having a mean particle diameter of at least about 20 times smaller than the mean particle diameter of the macro-particulates, wherein the degradable particulates are present in the particulate composition in an amount sufficient to reduce friction between the macro-particulates. Methods of using the particulate compositions and fluids are also disclosed.
    Type: Grant
    Filed: March 30, 2006
    Date of Patent: October 27, 2009
    Assignee: Halliburton Energy Services, Inc.
