  • Patent number: 10876029
    Abstract: Compositions, methods, and systems for mitigating annular pressure buildup in a wellbore. A method comprises introducing a spacer fluid into an annulus of the wellbore, wherein the spacer fluid comprises an aqueous base fluid, an acid swellable polymer, and a hydrolysable ester. The method further comprises allowing or causing to allow at least a portion of the spacer fluid to remain in the annulus; and allowing or causing to allow a temperature to increase in the annulus to the temperature sufficient to hydrolyze the hydrolysable ester; wherein hydrolysis of the hydrolysable ester produces an acid; wherein the acid reacts with the acid swellable polymer to produce a salt; and wherein the produced salt has a thermal expansion coefficient less than that of the aqueous base fluid.

  • Patent number: 10611953
    Abstract: It is common to require oil-well treating chemicals to be introduced into subterranean geological formations over the well's drilling, stabilization and extraction phases. The timely controlled and uniform release of such chemicals throughout the fluid bed vastly enhances their effectiveness. A method is disclosed for introducing such oil-well treating chemicals throughout the subterranean formation by encapsulating the chemicals within engineered composites, which are introduced into the subterranean formations along with the other fluids. These engineered composites are formed to slowly release the oil-well treating chemicals once they are in the subterranean formations as the engineered composites slowly dissolve.

    Abstract: The present invention relates to a method to form or obtain a high performance aqueous phase polymer fluid, which is a seawater-based drilling fluid for well drilling in low gradient formations. It is formulated based on liquid state polymer chemical products, easy to aggregate, and quickly mixed; a preparation and homogenization process that reduces preparation times, designed to drill hydrocarbon-producing deposits, focusing on minimizing damages to the producing formations, with a high rate of circulation loss in naturally fractured deposits. The system is environmentally-friendly, it complies with the main functions required of drilling fluids, while also providing a high inhibition control by swelling and dispersion of clay zones, due to the polymeric nature of the materials with which it is formulated. It is a fluid that does not contain solids in its formulation and provides an excellent transport and cleaning of drilling shears in the well.

    Abstract: A method for controlling fluid loss into the pores of an underground formation during fracturing operations is provided. Nanoparticles are added to the fracturing fluid to plug the pore throats of pores in the underground formation. As a result, the fracturing fluid is inhibited from entering the pores. By minimizing fluid loss, higher fracturing fluid pressures are maintained, thereby resulting in more extensive fracture networks. Additionally, nanoparticles minimize the interaction between the fracturing fluid and the formation, especially in water sensitive formations. As a result, the nanoparticles help maintain the integrity and conductivity of the generated, propped fractures.

  • Patent number: 8921285
    Abstract: Fluids viscosified with viscoelastic surfactants (VESs) may have their fluid loss properties improved with the presence of at least one mineral oil slurried together in combination with at least one particulate fluid loss control agent that may be an alkaline earth metal oxides, alkaline earth metal hydroxides, transition metal oxides, transition metal hydroxides, and mixtures thereof. The mineral oil having the particulate fluid loss control agents slurried within it may initially be dispersed oil droplets in an internal, discontinuous phase of the fluid. In one non-limiting embodiment, the slurry is added to the fluid after it has been substantially gelled. The mineral oil/particulate slurry may enhance the ability of a particulate fluid loss control agent to reduce fluid loss. The presence of the mineral oil may also eventually reduce the viscosity of the VES-gelled aqueous fluid.

  • Patent number: 8783350
    Abstract: Processes and systems for fracturing a formation are disclosed. Tools that may be selectively opened and closed are positioned on a tubular liner that in turn is positioned within a subterranean well bore. Separate pairs of packers are also attached to and positioned along the tubular liner so as to straddle each tool. Fracturing fluid is pumped from the surface through the tubular and open tool and past a pair of packers at a temperature and injection rate which causes contraction of the tubular liner. Thereafter, the velocity of the fracturing fluid is sufficient to set the pair of packers adjacent the open tool. Continued pumping of fracturing fluid is directed by the set packers into the adjacent subterranean environs at a pressure sufficient to fracture the subterranean environs.

  • Patent number: 8739878
    Abstract: The method disclosed herein includes the introduction of proppant-free stage and a proppant laden stage into the wellbore and/or subterranean formation. The method increases the effective fracture width and enhances fracture conductivity within the formation. Either the proppant-free stage or the proppant laden stage contains a breaker. The other stage contains a viscosifying polymer or viscoelastic surfactant to which the breaker has affinity. The proppant-free stage may be introduced prior to introduction of the proppant laden stage into the wellbore and/or formation. Alternatively, the proppant laden stage may be introduced into the wellbore and/or formation prior to introduction of the proppant-free stage.

  • Patent number: 8720555
    Abstract: A method for diverting fluids across a perforation tunnel in high-rate water pack operations may include providing a wellbore extending into a subterranean formation, wherein a perforation tunnel provides a fluid connection between the wellbore and the subterranean formation; providing a diverting particulate that comprises a degradable plasticized polymer coating on a particulate; placing the diverting particulate into the perforation tunnel, wherein the step of placing the diverting particulate forms a particulate pack within the subterranean formation and the perforation tunnel; allowing the degradable plasticized polymer coating to deform and fill the interstitial spaces within the particulate pack in the perforation tunnel such that the fluid conductivity between the wellbore and the subterranean formation is substantially blocked; and allowing the plasticized polymer coating to degrade over time thereby substantially restoring the fluid conductivity between the wellbore and the subterranean formation.
