20080200351 | Method of recycling fracturing fluids using a self-degrading foaming composition - A method of fracturing a subterranean zone penetrated by a well bore preparing a foamed fracturing fluid containing a self-degrading foaming composition with a mixture of anionic surfactant and nonionic surfactant, and a composition thereof. The fracturing fluid containing self-degrading foaming composition forms a substantially less stable foam when the foamed fracturing fluid is recovered during reclaim. | 08-21-2008 |
20080277620 | Polysaccharide based scale inhibitor - A depolymerized-carboxyalkyl polysaccharide formed by de polymerizing a polysaccharide having from 0.5 to 3.0 degrees of substitution and reducing the molecular weight of said polysaccharide before or after said depolymerizing provides a biodegradable scale inhibitor useful to prevent deposition of scale comprising, for example, calcium, barium, sulfate and salts thereof. The depolymerized carboxyalkyl polysaccharide is particularly useful in off shore oil production squeeze treatments and in the treatment of scale formed in industrial water treatment. | 11-13-2008 |

20110256085 | RHEOLOGY MODIFIER COMPOSITIONS AND METHODS OF USE - A composition for enhancing fluid viscosity including a mixture of at least one cationic or cationizable polymer and at least one anionic or anionizable (hydrolysable) polymer. The composition has a zeta potential at 25° C. in the range of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV, or is a precursor convertible at a temperature of 100 to 250° C. to the composition having a zeta potential at 25° C. of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV. Typically the compositions exhibit salt tolerance and interaction of both polymers at very high temperatures (>300° F.) such that the system exhibits an increase of viscosity at extreme temperatures. The compositions are useful for hydraulic fracturing, enhanced oil recovery, subterranean acidization, personal care as well as home and industrial cleaners. | 10-20-2011 |
