20140194326 - Compositions and methods for treatment of well bore tar: Of the many compositions and methods provided herein, one method includes contacting tar resident in a well bore with a tar stabilizer comprising an acrylonitrile-butadiene copolymer; and allowing the tar stabilizer to interact with the tar to at least partially reduce the tendency of the tar to adhere to a... Agent: Halliburton Energy Services, Inc.

20140194327 - Viscous fluid systems from waste water: By including a chemical additive in the well treatment fluid system design the cost and environmental impact of hydraulic fracturing may be substantially reduced. By adding a weak base to the well treatment fluid, water having a high, heterogeneous concentration of dissolved solids, such as water produced by oil and... Agent:

20140194328 - Thermoset ceramic compositions and a method of preparation therefor: Thermoset ceramic compositions and a method of preparation of such compositions. The compositions are advanced organic/inorganic hybrid composite polymer ceramic alloys. The material combine strength, hardness and high temperature performance of technical ceramics with the strength, ductility, thermal shock resistance, density, and easy processing of the polymer. Consisting of a... Agent:

07/03/2014 > 4 patent applications in 4 patent subcategories.

20140187449 - Functionalized silicate nanoparticle composition, removing and exfoliating asphaltenes with same: Removing an asphaltene particle from a substrate includes contacting a silicate nanoparticle with a chemical group to form a functionalized silicate nanoparticle, the chemical group includes a first portion; and a second portion comprising an aromatic moiety, the first portion being bonded to the silicate nanoparticle; contacting the asphaltene particle... Agent: Baker Hughes Incorporated

20140187450 - Internal breaker for fluid loss control pills and method: A method of treating a subterranean formation. The method may include providing a fluid-loss control pill that comprises an aqueous base fluid, a gelling agent, and an internal breaker that is selected from the group consisting of inorganic delayed acids or inorganic salts. The method can include introducing the fluid-loss... Agent: Superior Energy Services, L.L.C.

20140187451 - Producing nanostructure of polymeric core-shell to intelligent control solubility of hidrophilic polymer during polymer flooding process: Hydrophilic polymer particles have been obtained using polyacrylamide, xanthane, maleic anhydride polymers, allylamine, ethyleneimine, and oxazoline as core polymers. Then, hydrophobic polymers shells have been produced on the core-side using styrene, styrene copolymers, polyvinyl state, polysolfune, polymethyl methacrylate, and polycyclohxyl methacrylate by in-situ polymerization of monomer as method one and... Agent:

20140187452 - Treated geothermal brine compositions with reduced concentrations of silica, iron and manganese: This invention relates to treated geothermal brine compositions containing reduced concentrations of iron, silica, and manganese compared to the untreated brines. Exemplary compositions contain a concentration of manganese less than 10 mg/kg, a concentration of silica ranging from less than 10 mg/kg, and a concentration of iron less than 10... Agent: Simbol Inc

06/26/2014 > 2 patent applications in 2 patent subcategories.

20140179567 - Reversibly coagulatable and redispersable polymer including at least one monomer including a switchable-amphiphilic functional group and methods of using the same: The present invention relates to a polymer including at least one monomer comprising a switchable-amphiphilic functional group. Various embodiments provide a methods of treating a subterranean formation with the polymer, compositions including the polymer, and methods of making compositions including the polymer.... Agent: Halliburton Energy Services, Inc.

20140179568 - Method of using dithiazines and derivatives thereof in the treatment of wells: wherein R14 is a C1-C24 straight chain or branched alkyl group; or a C6-C24 aryl or arylalkyl group; R15 is a C1-C6 alkyl or a C6-C30 aryl or alkylaryl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid (WSF) formed by... Agent:

06/19/2014 > 2 patent applications in 2 patent subcategories.

20140171345 - Well treatment composites for use in well treatment fluids: A well treatment composite comprising a well treatment agent adsorbed onto a water-insoluble adsorbent may be prepared by precipitating the well treatment agent, in the presence of a metal salt, from a liquid while the well treatment agent is being adsorbed onto the water-insoluble adsorbent. After a treatment fluid containing... Agent:

20140171346 - Drilling fluid for enhanced rate of penetration: A drilling fluid is provided which results in an enhanced rate of penetration, and more particularly, a drilling mud composition is provided with a reduced ester content which maintains an enhanced rate of penetration.... Agent: Suncor Energy Inc.
