  • Apparatuses and methods for testing wellbore fluids
    Patent number: 9528365
    Abstract: An apparatus may be used to test the ability of a first fluid to remove a second fluid from a surface. The apparatus comprises a reservoir that contains the first fluid and a testing cell that contains the second fluid. The testing cell also contains a rotor within. The first fluid is pumped into the testing cell, thereby displacing the second fluid. The displaced second fluid flows to a collection vessel. The apparatus is particularly useful for determining the ability of a chemical wash or a spacer fluid to remove non-aqueous drilling fluids from a metallic surface.

  • Compositions and Methods for Completing Subterranean Wells
    Publication number: 20150240142
    Abstract: Well treatment compositions comprise water, a lipophilic anionic surfactant, a hydrophilic non-ionic surfactant, a second non-ionic surfactant and a water-miscible solvent. Optionally, a second solvent may be incorporated. When added to spacer fluids, chemical washes or both, the compositions promote the removal of non-aqueous drilling fluids from casing surfaces. Additionally, the treated casing surfaces are water wet, thereby promoting optimal bonding to cement.
