20100307744 | USE OF ENCAPSULATED CHEMICAL DURING FRACTURING - A process for hydraulic fracturing of a subterranean reservoir formation penetrated by a wellbore includes pumping a fracturing fluid or other aqueous fluid which is an aqueous suspension of particles which each comprise an oilfield chemical distributed within an encapsulating matrix of water-insoluble carrier_material from the surface via the wellbore and into the reservoir. The encapsulating matrix is chosen so as to provide a delayed release of the oilfield chemical from the particles into surrounding fluid, such that oilfield chemical is liberated from the particles after they have entered the fracture. The encapsulating matrix may be a polymer which is at least partially amorphous, with a glass transition temperature below the reservoir temperature. | 12-09-2010 |

20100307747 | ENGINEERED FIBERS FOR WELL TREATMENTS - Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers. | 12-09-2010 |
20120090835 | DOWNHOLE MATERIAL-DELIVERY SYSTEM FOR SUBTERRANEAN WELLS - Methods for releasing tracers into a well for diagnostic studies during subterranean-well operations comprise filling one or more hollow bodies with substances The system that comprise a cementing-plug-launching system, a drill string, casing, coiled tubing, wireline or combinations thereof. After the system is lowered into the well, the tracer substance may be remotely and safely released into the well. | 04-19-2012 |
20120205102 | Well Treatment - The following describes a novel and alternative mechanism in regards to releasing reactive chemicals. Namely, utilizing shells containing multiple emulsions that can be blended with the base fluids, and then react with said base fluid upon exposure to a trigger e.g. high shear and/or elongation flow, therefore plugging even large fractures. Such gelling lost circulation material allows to obtain a reliable carrier and fast reaction when triggered. | 08-16-2012 |
