| 20090008094 | Method of Treating Subterranean Formations With Porous Ceramic Particulate Materials - Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems. | 01-08-2009 |
| 20090044942 | Cellulosic Particulates and Method of Manufacture and Use Thereof - Spherical porous and non-porous cellulose particulates for use in sand control as well as stimulation procedures, may be prepared by first dissolving cellulosic materials (such as fibrous cellulose, wood pulp linters, cotton balls and/or paper), in the substantial absence of water or a nitrogen-containing base, in an ionic liquid. The solution is then combined with a cellulose-insoluble liquid to render the spherical particulates. The surface of the cellulosic particulates may be treated with a coating or penetrating layer. | 02-19-2009 |
| 20090325825 | Method of Minimizing or Reducing Salt Deposits By Use of a Fluid Containing a Fructan and Derivatives Thereof - The amount of crystallized salt in an oil and/or gas well may be minimized or reduced by use of a fructan, such as inulin, or a derivative as a salt block inhibitor. A preferred salt inhibitor is the salt of carboxyalkyl inulin such as a sodium salt of carboxymethyl inulin. The salt block inhibitor may be adsorbed onto a water-insoluble adsorbent. | 12-31-2009 |
| 20100197530 | OIL FIELD TREATMENT FLUIDS WITH VISCOSIFIED BRINES - The present disclosure is directed to a method comprising introducing into a well bore a fluid comprising a zwitterionic polymer. The polymer is prepared by inverse emulsion polymerization of at least one monomer A | 08-05-2010 |
| 20100206569 | THERMOTHICKENER POLYMER AND SURFACTANT COMPOSITION AND METHODS OF EMPLOYING THE COMPOSITION - The present disclosure is directed to a thermothickening composition comprising: a surfactant; and a thermothickening polymer that is the product of at least the following monomers: a non-ionic hydrosoluble unsaturated amide monomer; an ionic monomer; and an unsaturated dicarboxylic acid half ester having a heat sensitive functional group. | 08-19-2010 |
| 20100222243 | Porous Particulate Materials and Compositions Thereof - Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials.
