20140349894 | NANOFLUIDS AND METHODS OF USE FOR DRILLING AND COMPLETION FLUIDS - Nanomaterial compositions are useful for applications in drilling and completion fluids as enhancers of electrical and thermal conductivity, emulsion stabilizers, wellbore strength improvers, drag reduction agents, wettability changers, corrosion coating compositions and the like These nanomaterials may be dispersed in the liquid phase in low volumetric fraction, particularly as compared to corresponding agents of larger size. Nanofluids (fluids containing nano-sized particles) may be used to drill at least part of the wellbore. Nanofluids for drilling and completion applications may be designed including nanoparticles such as carbon nanotubes. These fluids containing nanomaterials, such as carbon nanotubes, meet the required rheological and filtration properties for application in challenging HPHT drilling and completions operations. | 11-27-2014 |

20100314118 | Liquid Crystals for Drilling, Completion and Production Fluids - Fluids containing liquid crystal-forming surfactants or polymeric surfactants, or polymers, or complex polymers or copolymers, or graphite nanotubes or Janus particles in a polar and/or non polar liquid, and optionally, co-surfactants, are useful in drilling, completion and production operations to give increased viscosity (solids suspension ability) and/or decreased fluid loss, as compared to otherwise identical fluids absent the liquid crystals. These liquid crystal compositions contain organized micelles. The liquid crystal-containing fluids are useful in completion fluids, fracturing fluids, formation damage remediation, waste management, lost circulation, drilling optimization, reducing trapped annular pressure during the hydrocarbon production process, well strengthening, friction and drag reducers, fluids introduced through an injection well, for geothermal wells, and the controlled release of additives into a wellbore, at a subterranean formation or at the oil production facilities. | 12-16-2010 |

20120241220 | Dendritic Surfactants and Extended Surfactants for Drilling Fluid Formulations - 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. | 09-27-2012 |
