  • Patent number: 9688901
    Abstract: The disclosed invention is a unique drilling fluid composition and method for reducing lost mud circulation in wellbores due to seepage loss into fluid permeable subterranean formations. The drilling fluid composition comprises a variety of shapes and sizes of distinctive unadulterated elastomeric rubber particles derived from the tire retreading (recapping) process. These elastomeric rubber particles are incorporated into an aqueous, hydrocarbon, or synthetic drilling fluid in sufficient amounts as to plug holes, fractures, and fissures, form a mud cake, and thus stem the loss of drilling fluids from the lost circulation zone.

  • Patent number: 9394779
    Abstract: A method for hydraulically isolating a portion of a multizone wellbore by providing a plug proximate the portion of the wellbore. The plug may be a proppant combined with a polymer. The proppant may be an ultra-lightweight proppant and the polymer may be cross-linked. The polymer may be a superabsorbent polymer or a hydrophobically modified polysaccharide. The plug may be formed by placing a pill of proppant and polymer within the wellbore and slowing pumping fluid down to cause the pill to bridge off and form a plug. The pill may also include a lightweight filler. The plug may be used to hydraulically isolate a portion of the wellbore during a fracturing or re-fracturing process. Multiple plugs may be placed along the wellbore to hydraulically isolate portions of the wellbore during the fracturing or re-fracturing process.

  • Patent number: 9334438
    Abstract: This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a rheologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in-water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.
