  • Application of polyelectrolyte complex nanoparticles to fluid loss control of oil well cementing
    Patent number: 11649392
    Abstract: A variety of fluid loss control compositions and methods are provided for controlling fluid loss in a cementing operation. As described herein, polyelectrolyte complex nanoparticles and fluid loss control compositions containing polyelectrolyte complex nanoparticles can be effective for fluid loss control in a variety of cementing operations. Methods of making and methods of using the electrolyte complex nanoparticles and fluid loss control compositions containing polyelectrolyte complex nanoparticles are also provided. The polyelectrolyte complex nanoparticles can include a polycation polymer such as a branched chain polyethylenimine, and a polyanion polymer such as polyacrylic acid or poly(vinylsulfonic) acid. The polyelectrolyte complex nanoparticles can contain additional additives such as metal ions or fluid loss additives such as a cellulose polymer.
