20100175880 | Method of Using Crosslinkable Brine Containing Compositions - A method of enhancing the productivity of a subterranean formation penetrated by a gas, oil or geothermal well consists of introducing into the formation and/or well a pumpable polymerizable fluid comprising a crosslinkable, mono functional alkene, multi-functional alkene (such as a difunctional alkene), a heat inducible free radical initiator and brine. The fluid may be used in the thermal insulation of production tubing or transfer pipes and hydraulic fracturing. | 07-15-2010 |
20110114314 | Water Control Additive Compounds and Methods of Making and Using Same - Compositions and methods of reducing a flow of aqueous liquids through a subterranean formation are provided. The compositions and methods are used for water control. The compositions include a water control additive that is prepared by reacting a soluble sodium silicate and a hydrolysable organosilane compound to produce silanol that reacts and forms a bond with the formation thereby producing a binding polysiloxane. | 05-19-2011 |
20120208726 | COMPOSITION AND METHOD FOR REMOVING FILTER CAKE - An embodiment of the present disclosure is directed to a well servicing fluid emulsion. The well servicing fluid is formulated with components comprising an ester of an organic acid for which the pK | 08-16-2012 |
