20110207633 | DEEP EUTECTIC SOLVENTS AND APPLICATIONS - A method of solubilizing/removing cellulose or chemically-modified cellulosic polymers utilized in subterranean drilling operations such as fracturing. The method involves introducing a deep eutectic solvent (DES) into a subterranean region. Deep eutectic solvents useful as cellulose solvents include quaternary ammonium compounds, including choline chloride and chlorcholine chloride, reacted with a compound selected from amides, amines, carboxylic acids alcohols, and metal halides. The DES material can be pumped downhole after fracturing operations to remove cellulosic material used, for example, to thicken fracturing fluid which is left behind in the created fractures, on the face of the formation, along the wellbore, or elsewhere within the subterranean region. The DES can be used alone or in a sequential treatment protocol, whereby the DES is introduced into the subterranean region, followed by post-treatment introduction of water, caustic, acid or anhydride into the subterranean as a flush. | 08-25-2011 |
20110068292 | SYNTHETIC REFRIGERATION OIL COMPOSITION FOR HFC APPLICATIONS - Novel refrigeration compositions comprising at least one ester of a hydroxycarboxylic acid which can have a chain length in the range of from 8 to 22 carbon atoms. The composition can contain a carrier fluid or base oil selected from alkylbenzenes, alkylated naphthenics, polyalkylene glycols, polyvinylethers, polyalphaolefins, mineral oils, polyol esters, and combinations thereof, providing improved fluidity and heat transfer, and enhanced oil return. A method of making a refrigeration composition by preparing at least one ester by esterifying a first component comprising at least one hydroxycarboxylic acid with a second component comprising at least one alcohol and combining the at least one ester with a base oil selected from the group consisting of alkylbenzenes, alkylated naphthenics, polyalkylene glycols, polyvinylethers, polyalphaolefins, mineral oils, polyol esters, and combinations thereof. | 03-24-2011 |

20090247429 | SHALE HYDRATION INHIBITION AGENT(S) AND METHOD OF USE - A water-based drilling fluid and method of using same are presented in this disclosure, which fluid is used in drilling wells through a formation containing a shale that swells in the presence of water. The drilling fluid comprises an aqueous based continuous phase; a weighting material; and a shale hydration inhibition agent (SHIA) selected from the group consisting of propylamine derivatives, hydrogenated poly(propyleneimine) dendrimers (HPPID), and polyamine twin dendrimers (PTD). In some embodiments, the SHIA of this disclosure is not hydrolyzed at a temperature in the range of from about 100° F. to about 500° F. The drilling fluid may further comprise a fluid loss control agent, an encapsulating agent, other additives, and combinations thereof. A method of reducing shale swelling during wellbore drilling is also described. The method comprises circulating in the subterranean well a water-based drilling fluid comprising an aqueous based continuous phase, a weighting material, and a SHIA. | 10-01-2009 |
