    Abstract: Drilling fluids comprising a carrier fluid; a weighting agent that comprises sub-micron precipitated barite; a particle having a specific gravity of greater than about 2.6; and, a bridging agent that is not the submicron-precipitated barite or the particle. The weighting agent has a particle size distribution such that at least 10% of particles in the sub-micron precipitated barite have a diameter below about 0.2 microns, at least 50% of the particles in the sub-micron precipitated barite have a diameter below about 0.3 microns and at least 90% of the particles in the sub-micron precipitated barite have a diameter below about 0.5 microns. The particle has a specific gravity of greater than about 2.6 is not sub-micron precipitated barite. The ratio of the sub-micron precipitated barite to the particle is about 10:90 to about 99:1. The bridging agent comprises a degradable material.

  • Patent number: 8293686
    Abstract: A water-based polymer drilling fluid, containing effective quantities of surfactants having HLB numbers equal to or greater than approximately 7, emulsifies oil and bitumen contained in oil sand cuttings, resulting in the oil and bitumen being dispersed into the mud as an emulsion. This eliminates or significantly reduces the ability of the oil, bitumen, and cuttings to clog the well or stick to drill string components when drilling a well through oil-bearing sands, particularly sands containing highly viscous oil or bitumen. The emulsification process separates the sand particles from the oil and bitumen, such that the sand particles can be removed when the mud is run through a conventional shale shaker or other suitable apparatus.

  • Publication number: 20120245058
    Abstract: A base fluid may contain graphene nanoparticles where the base fluid may include an oil-based fluid, a water-based fluid, and combinations thereof. The oil-based fluid may be a brine-in-oil emulsion, or a water-in-oil emulsion, and the water-based fluid may be an oil-in-water emulsion, or an oil-in-brine emulsion; and combinations thereof. The addition of graphene nanoparticles to the base fluid may improve one or more properties of the fluid, which may include the flow assurance properties of the fluid, the fluid loss control properties of the fluid, the rheological properties of the fluid, the stability of the fluid, the lubricity of the fluid, the electrical properties of the fluid, the viscosity of the fluid, the thermal properties of the fluid, and combinations thereof. The fluid may be a drilling fluid, a completion fluid, a production fluid, and/or a servicing fluid.

  • Publication number: 20120241220
    Abstract: Modified surfactants may be added to an oil-based drilling fluid where the modified surfactant is selected from the group consisting of an extended surfactant, a dendritic surfactant, a dendritic extended surfactant, and combinations thereof. These oil-based drilling fluids may be used for drilling a well through a subterranean reservoir, while circulating the oil-based drilling fluid through the wellbore. The oil-based drilling fluid may include at least modified surfactant, at least one non-polar continuous phase, and at least one polar non-continuous phase. The modified surfactant may have propoxylated/ethoxylated spacer arms extensions. The modified surfactant may have intramolecular mixtures containing hydrophilic and lipophilic portions. They attain high solubilization in the oil-based drilling fluid and may be, in some instances, insensitive to temperature making them useful for a wide variety of oil types.

  • Patent number: 8242059
    Abstract: Oil-based wellbore fluid in the form of an emulsion having a continuous phase containing an oil and, dispersed therein, a first dispersed liquid phase and a second separate dispersed liquid phase. The first dispersed liquid phase is a brine phase containing at least 5% by weight of a dissolved salt or a mixture of salts, and the second dispersed liquid phase is a polar organic liquid which is insoluble or sparingly soluble in the brine and contains the first dispersed liquid phase, but is soluble in pure water. The second dispersed liquid phase is in the form of droplets having an average diameter of not less than 5 microns.
