  • Patent number: 10655050
    Abstract: A method for controlling loss circulation. The method includes introducing into a wellbore a nanosilica drilling fluid comprising water and an alkaline nanosilica dispersion. The method further includes introducing into the nanosilica drilling fluid an amount of a chemical activator comprising a water soluble hydrolysable polyester to produce a convertible drilling mud where the convertible drilling mud has an initial pH between 8 and 11 upon formation. The method also includes allowing the chemical activator to hydrolyze to produce an acid and reduce the pH of the convertible drilling mud to less than a gel pH, thereby converting the convertible drilling mud into a solid gel lost circulation material. A convertible drilling mud operable to convert into a solid gel lost circulation material is also provided.

  • Publication number: 20090044726
    Abstract: A novel cement slurry composed of cement and water that can be used in cement stabilization applications. The cement slurry compound itself is chemically treated, by means of a cellulosic or other thixotropic thickening agent(s) to create a thixotropic system wherein the wetted cement remains in suspension and does not settle out prior to use even without further mixing. A chemical retarder/stabilizer is also used to prevent the slurry from prematurely setting during shipping. A novel apparatus and method for mixing the novel cement slurry is disclosed to insure the exact proportioning of all ingredients and the proper wetting of the cement.

  • Patent number: 7387674
    Abstract: Disclosed herein are a method for solidifying soil and industrial waste and a solidified material prepared thereby. The solidified material of soil and industrial waste is prepared by adding 2-6 parts by weight of a 3-5-fold dilution of a solidifying agent and 3-15 parts by weight of cement to 100 parts by weight of soil, industrial waste or a mixture of two or more thereof. The solidified material prepared according to this method has excellent density, strength, elasticity and durability, and thus can be used as a substitute for stone material. Also, it can be advantageously used in high-temperature and high-humidity areas, because external impact or pressure is relieved because it is absorbed by asphalt.

  • Patent number: 7276114
    Abstract: The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called “oil and gas waste,” more specifically, drilling waste and aggregate and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.
