20160102246 | Stabilization of High Molecular Weight Polysaccharide Solutions at High Temperatures - A fluid mixture containing a high molecular weight polysaccharide composition with improved viscosity stability at high downhole temperatures and pressures encountered in common oil field applications, including hydraulic fracturing stimulation, drilling, cementing, and coil-tubing. The composition includes a salicylic acid solution, which, being a free-radical scavenger, prevents free-radical reactions within the high molecular weight polysaccharide that would otherwise adversely affect viscosity. The composition may also include an ascorbic acid solution, which reduces at least a portion of the oxidized salicylic acid to restore its function as a free-radical scavenger to prevent additional free-radical reactions with the high molecular weight polysaccharide. An alcohol solvent may also be utilized to increase the solution loading of salicylic acid. | 04-14-2016 |
20120175120 | METHOD FOR INTERVENTION OPERATIONS IN SUBSURFACE HYDROCARBON FORMATIONS - Nanoparticles are added to a fluid containing a wetting agent and the fluid is pumped down a well to enhance wetting of solid surfaces in and around the well before pumping an acid solution down the well. After acid is pumped, a fluid containing nanoparticles and wetting agent is again pumped down the well, leading to improved flow capacity of the well. | 07-12-2012 |
20120168165 | METHOD FOR INTERVENTION OPERATIONS IN SUBSURFACE HYDROCARBON FORMATIONS - Nanoparticles are added to a fluid containing a wetting agent to enhance wetting of solid surfaces in and around the well and removing a water-block from the well. The wetting agent and nanoparticles combine to produce a wetting of the surfaces of the rock that allows recovery of the excess water near the well (water block). | 07-05-2012 |
