  • Patent number: 9624421
    Abstract: Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure. The contaminant removal component removes contaminants, especially dissolved contaminants, in the subterranean water or hydrocarbon before the water/hydrocarbon leaves the well. For those contaminant removal components that can be regenerated, such as ion exchange resins, a measured quantity of an acidic regeneration solution can be injected into the fractured stratum for regeneration and recovered when the well resumes production.

  • Patent number: 9556377
    Abstract: Chelating agents are often used in conjunction with stimulation operations in a subterranean formation to address the presence of certain metal ions therein. Hydrophobically modified chelating agents can be used to form metal-ligand complexes in a subterranean formation that can sometimes exhibit significantly different behavior than do their more water-soluble variants. Methods for treating a subterranean formation can comprise: providing a treatment fluid comprising a hydrophobically modified aminopolycarboxylic acid chelating agent, the chelating agent comprising an N-substitution having no carboxylic acid groups and about 6 carbon atoms or more; introducing the treatment fluid into a subterranean formation; and complexing metal ions in the subterranean formation with the chelating agent to form a metal-ligand complex.

  • Patent number: 9540903
    Abstract: An emulsion is mixed with fibers while the emulsion is moving through a surface tubing using a venturi. The fiber/emulsion mixture is injected into a pressurized tank and the pressurized fiber/emulsion mixture is injected from the pressurized tank into a desired location in a wellbore. Pumps and pressure boosters may be used to move the fluid. Alternatively, an emulsion and a fiber suspension is provided and a first downhole tubing disposed in a wellbore conveys the emulsion downhole while a second downhole tubing disposed in the wellbore and circumferentially enclosing all or part of the first downhole tubing conveys the fiber suspension downhole. The first downhole tubing has nozzles through which the emulsion passes into the second downhole tubing and the emulsion and the fiber suspension mix. The mixture exits the second downhole tubing through ports at a desired location in the wellbore.

  • Patent number: 9152646
    Abstract: A creation order of content items can generally be determined by a metadata creation time associated with the content items. In some instances, multiple content items can be associated with the same metadata creation time. To determine the order of content items associated with the same metadata creation time, a files system modification time for the content items can be accessed. The file system modification time may indicate time in a smaller time increment than the metadata creation time. If the creation order of the content items cannot be determined from the file system modification time, the names of the content items can be analyzed to determine if they indicate a creation order. Alternatively the order the content items are placed in memory can be used to determine the creation order. Metadata identifying the determined creation order of the content items can be appended to the content items.

  • Patent number: 9040467
    Abstract: Solid proppants are coated with a coating that exhibits the handling characteristics of a precured coating while also exhibiting the ability to form particle-to-particle bonds at the elevated temperatures and pressures within a wellbore. The coating includes a substantially homogeneous mixture of (i) at least one isocyanate component having at least 2 isocyanate groups, and (ii) a curing agent. The coating process can be performed with short cycle times, e.g., less than about 4 minutes, and still produce a dry, free-flowing, coated proppant that exhibits low dust characteristics during pneumatic handling but also proppant consolidation downhole for reduced washout and good conductivity.

  • Patent number: 9034806
    Abstract: Methods for treating a subterranean formation penetrated by a wellbore where shear recovery time of viscoelastic surfactant treatment fluids is shorten by adding an effective amount of an fiber based rheology enhancer. The rheology enhancer also increases fluid viscosity. Further, the rheology enhancer also improves proppant settling. Some examples of surfactants are betaines and quaternary amines, and an example of fiber based rheology enhancer is polylactic acid fiber. The fluids are useful in oilfield treatments, as well as methods of preparing viscoelastic surfactant based fluids.

  • Publication number: 20150133349
    Abstract: Two intermediates that have known separate efficacy for preventing scales such as calcium carbonate, magnesium carbonate and barite (barium sulfate) were discovered to have a synergistic effect for preventing or inhibiting silicate scaling when used together. Each of these intermediates is ineffective at preventing silicate scaling when used alone; however, when used in combination, they have a synergistic benefit. In one non-limiting embodiment the components include a polyamine phosphonate and a lysine tetra(alkylene)phosphonate.
