20080312107 | Process for treating underground formations - A process for disrupting filter cake in an underground formation, which includes (i) incorporating into a treatment fluid a solid polymer capable of being converted by hydrolysis into one or more organic acids; (ii) introducing the treatment fluid into the underground formation; and (iii) allowing the solid polymer to hydrolyze in the presence of water to produce organic acid such that acid soluble material within the filter cake or adjacent formation is dissolved. | 12-18-2008 |
20110059871 | Graphene Compositions And Drilling Fluids Derived Therefrom - Drilling fluids comprising graphenes and nanoplatelet additives and methods for production thereof are disclosed. Graphene includes graphite oxide, graphene oxide, chemically-converted graphene, and functionalized chemically-converted graphene. Derivatized graphenes and methods for production thereof are disclosed. The derivatized graphenes are prepared from a chemically-converted graphene through derivatization with a plurality of functional groups. Derivatization can be accomplished, for example, by reaction of a chemically-converted graphene with a diazonium species. Methods for preparation of graphite oxide are also disclosed. | 03-10-2011 |
20120010109 | HYDRODEWAXED HYDROCARBON FLUID USED IN THE MANUFACTURE OF FLUIDS FOR INDUSTRIAL, AGRICULTURAL, OR DOMESTIC USE - Hydrocarbon fluid which can be used in the composition of industrial, agricultural and household products, with a pour point of less than −15° C. according to ASTM standard D97, initial and final boiling points between 200 and 450° C., containing more than 50% by weight of isoparaffins and naphthenes up to at most 40% by weight, and constituted by a mixture of hydrocarbons obtained by distillation of hydrodewaxed gas-oil cuts with a boiling point greater than 200° C. | 01-12-2012 |
20150065400 | COMPOUND OF BIODEGRADABLE SURFACTANTS FOR SEPARATING IMPURITIES IN A HYDROCARBON - Compounds of biodegradable surfactants useful for optimizing the separation of impurities typical of hydrocarbons, and designed to intervene and stabilize the molecular structure of crude oil, with no significant alterations of the crude's intrinsic composition are disclosed. The biodegradable surfactants compounds coexist with a non-ionic surfactant and an organic mix in emulsion form with the purpose of isolating crude from the pipeline, reduce friction to improve crude flow and to enter the crude macromolecule to modify the hydrocarbon chain to reduce its density and thus its viscosity; including compounds of biodegradable surfactants that comprise sodium hydroxide 1N, potassium chloride, sulphonic acid, dodecanoic acid, nonylphenol, terpene-1 and water, preferably hard water. | 03-05-2015 |
20160160110 | WELLBORE SERVICING COMPOSITIONS AND METHODS OF MAKING AND USING SAME - A method of servicing a wellbore comprising identifying lost circulation zone within a wellbore; and placing in the wellbore a composition comprising a wax and a water-based mud wherein placement of the composition reduces or prevents a loss of fluids to the lost circulation zone. A wellbore servicing fluid comprising a water-based mud, a sized calcium carbonate particle and a wax. | 06-09-2016 |
