20120231977 | Thermal Insulating Fluids - Aqueous and substantially anhydrous fluids having particularly low thermal conductivities and variable densities are disclosed. The fluids include: one or more organic and/or inorganic salts and at least one aprotic polar organic solvent, a mixture of aprotic and erotic polar organic solvents, and/or a polar organic solvent having both prone and aprotic polar functional group linkages. The fluids optionally include one or more viscosifying agents and are free of cross-linking agents. Methods for formulating and using the fluids are also disclosed. | 09-13-2012 |

20100132951 | Controlled De-functionalization of Filtercakes and Other Downhole Compositions - A method for the controlled de-functionalization of downhole polymers comprising contacting downhole, water-dispersible, polymeric material with a dehydrating agent until the water-dispersible polymeric material is sufficiently de-functionalized to be removed. The water-dispersible polymeric material can be found in the downhole formation of a filtercake on production walls, other downhole polysaccharide materials and in fluid loss pills. The contact between the dehydrating agent and the polymeric material is prolonged until the water-dispersible, polymeric material is sufficiently de-functionalized to allow the de-functionalized material to be removed by flushing the drilling fluid. The dehydrating agent is selected from concentrated inorganic salt solutions, concentrated organic salt solutions, acid anhydrides, esters, alcohols, ethers, ketones, aldehydes, amides, organic acids and mixtures thereof. | 06-03-2010 |

20150357740 | Contact Element And Method For Producing A Contact Element - A contact element is disclosed and includes a body of contact material, a mating plug end, a conductor end, and a fold-over layer of the contact material. The mating plug end is positioned at one end of the body, while the conductor end is positioned an opposite end of the body with respect to the mating plug end. The mating plug end includes a conductor-side cross-width less than a plug-side cross-width of the mating plug end. The fold-over layer of the contact material is disposed along at the mating plug end. | 12-10-2015 |
