  • Publication number: 20200255624
    Abstract: Provided are compositions, systems, and methods of using a synthetic latex composition for treating a subterranean formation. An example method comprises providing a synthetic latex composition comprising: a synthetic latex and a latex stabilizer; and exposing the synthetic latex composition to air for an exposure period of at least one day; wherein the synthetic latex composition loses less than 5% of its initial water concentration at the end of a one-day exposure period. The synthetic latex composition may be further included in a treatment fluid. The treatment fluid may be introduced into a wellbore penetrating a subterranean formation.

  • Patent number: 9719965
    Abstract: Systems and methods of determining settlement characteristics of a drilling mud are disclosed. Conditions under which heavier elements of the drilling mud settle under the influence of gravity can be determined. Samples of drilling mud can be placed in testing cells, and ultrasonic test pulses can be transmitted through the samples. Responses to the test pulses can be detected and compared to other responses detected at different vertical positions within the testing cell. Settlement can be detected when the responses from different vertical positions are generally dissimilar. An environmental temperature of the testing cell can be changed over a testing time interval, and a settlement temperature can be determined by detecting a divergence in the responses from different vertical positions.
