  • Polymeric acid precursor compositions and methods
    Patent number: 8604111
    Abstract: A composition is formed from a polymeric acid precursor, such as polylactic acid (PLA), that is a least partially dissolved within a polymer dispersing solvent. An emulsion may be from polymeric acid precursor that is at least partially dissolved within a solvent and a liquid that is substantially immiscible with the solvent. In certain cases, the molecular weight of the polymeric acid precursor may be reduced in forming the solution. The solution may be used in treating a formation penetrated by a wellbore.
    Type: Grant
    Filed: April 24, 2012
    Date of Patent: December 10, 2013
    Assignee: Schlumberger Technology Corporation
    Inventors: Dean M. Willberg, Carlos Abad, Marina Bulova, Dzanis Menshikau
