  • Patent number: 11118095
    Abstract: Treatment fluids containing salts, surfactants, mutual solvents and fibers may be used to remove wellbore filter cakes that have been deposited by drilling fluids. The drilling fluids may be water-base, oil-base, synthetic-base or emulsions. The fibers may be selected from polylactic acid, celluloses, polyesters, polyvinyl alcohols and polyethylene terephthalates. A combination of straight and crimped fibers is present in the treatment fluid.

  • Patent number: 10793765
    Abstract: A method for treating a subterranean formation containing shale includes introducing to the subterranean formation a shale stabilizer, a surfactant, and a triggering agent simultaneously with or prior to introducing an alkali silicate to the subterranean formation, and allowing the alkali silicate and triggering agent to react to form a reaction product. Methods include coating the surface of at least a portion of the shale with the reaction product.

  • Publication number: 20160341017
    Abstract: A method includes positioning at least one fluid nozzle disposed upon a distal end of a fluid conduit in a cased borehole penetrating a subterranean formation at a target zone of the subterranean formation. An abrasive laden fluid is then continuously pumped through the fluid conduit and through the at least one fluid nozzle at a pressure adequate to form at least one slot through the cased borehole. The abrasive fluid contains an aqueous medium, an abrasive, an optional acid, and a viscoelastic surfactant. While continuously pumping the abrasive fluid through the fluid conduit, the wellbore may be cleaned by returning debris and material generated in the operation to the surface with the fluid. In some instances, a portion of the forming a slot through the cased borehole is conducted simultaneous with the cleanout of the wellbore.

  • Publication number: 20150166871
    Abstract: Cement compositions for well cementing operations comprise an isocyanate compound and solid particles. The solid particles are present in at least three distinct particle size groups. The compositions may further comprise a blocking agent and solvents such as polyols, hydrocarbon solvents, diesel or water. The compositions are particularly useful in the context of remedial cementing, which may be squeeze cementing or plug cementing.

  • Publication number: 20110186293
    Abstract: A method and apparatus to treat a subterranean formation including introducing a fluid comprising degradable material into a wellbore, contacting a surface of the wellbore with the fluid, and stimulating a surface of a subterranean formation, wherein the contacting the wellbore surface and stimulating the formation occur over a time period that is tailored by the properties of the degradable material. In some embodiments, the properties of the degradable material include a chemical composition, a surface area, a geometric shape of a particle of the material, a concentration of the material in the fluid, a density of the material, a dimension of a particle of the material, or a combination thereof.

  • Publication number: 20090143257
    Abstract: A composition for treatment of a subterranean formation, which may be used for water control, is comprised of at least one of 1) a premix of an oleochemical polyol, at least one of polyisocyanate, polycyanate and polyisothiocyanate, and a blocking agent to temporarily block all or a portion of free reactive groups of said at least one of polyisocyanate, polycyanate and polyisothiocyanate. Alternatively, or in addition, the composition may be comprised of a solvent and 2) a polyurethane prepolymer formed by reacting an oleochemical polyol and at least one of polyisocyanate, polycyanate and polyisothiocyanate. A blocking agent may also be used with the polyurethane prepolymer. The composition may be used in a method of treating a subterranean formation penetrated by a wellbore by introducing the composition into the formation through the wellbore.

  • Publication number: 20060062275
    Abstract: A color contour of an object is displayed from information that is obtained using an array of thermopile sensors. A color contour of an object is generated by pre-establishing a relationship between IR radiation power and color, measuring the power of incident IR radiation emanating from different locations on the object, mapping the measured IR radiation powers to colors, and generating color contour information that can be displayed on a color display. The color contour information represents the temperature of an object at different locations.

  • Publication number: 20050206612
    Abstract: An image control accelerometer system and method are disclosed. For example, an image control accelerometer system can include an accelerometer module, a movement analysis module, and an input protocol generation module. The accelerometer module is communicatively coupled to the movement analysis module which is communicatively coupled to the input protocol generation module. The accelerometer module detects movement of the image control accelerometer system. The movement analysis module then determines a direction of the movement. Once the movement direction is determined, the input protocol generation module generates a signal that indicates the direction of the movement.
