20160047188 | MOLDED SHEAR SLIP - A molded slip assembly comprises a shear ring coupled to a plurality of slip segments to form a unitary solid ring and a plurality of drillable bases. A drillable base is molded to an inner surface of each of the plurality of slip segments. | 02-18-2016 |
20140144620 | ELECTROSTATICALLY COATED COMPOSITES - Herein disclosed is a method of electrostatically coating a composite object comprising: a) Pretreating a surface of the composite object with a composition to induce conductivity; b) Applying a charge to the object after surface pretreatment; and c) Electrostatically applying a coating material to the object. In an embodiment, the method comprises cleaning the surface of the composite object prior to pretreating. Also described is a composite downhole tool pretreated with a surface pretreatment composition and electrostatically coated. In an embodiment, the composite downhole tool comprises bridge or frac plug mandrels, wedges, sleeves, noses, cones, mule shoes, extrusion limiters, slips, baffles, landing seats, frac balls, wireline tools, housings for measurement-while-drilling, housings for logging-while-drilling, or tubular parts. | 05-29-2014 |
20140072740 | METHOD AND APPARATUS FOR RESIN FILM INFUSION - In this disclosure, filament winding method and system without a resin dip bath are disclosed. The method comprises feeding a fiber on a mandrel without dipping the fiber in a resin bath; and applying a resin onto the fiber at the point of where the fiber contacts the mandrel. In an embodiment, the fiber comprises carbon fiber, basalt fiber, S-glass fiber, S-2 glass fiber, A-glass fiber, C-glass fiber, E-glass fiber, D-glass fiber, Kevlar fiber, ECR glass fiber. In an embodiment, the resin comprises polyester resin, vinylester resin, epoxy resin, phenolic resin, BMI resin, polyurethane resin, cyanate ester resin. In an embodiment, the fiber is fed on the mandrel at an angle of from about 25° to 65°, wherein the angle is defined as the angle between the fiber and a horizontal plane when the mandrel is placed horizontally. Further disclosed are parts made according to the instant filament winding method. | 03-13-2014 |
20140020911 | DOWNHOLE TOOL SYSTEM AND METHOD RELATED THERETO - A slip and cone assembly for a downhole tool that includes a composite slip having a one-piece configuration and having at least two grooves disposed therein; and a cone having a first end configured for engagement with the composite slip, wherein the composite slip and the cone are configured for application of a load therebetween that results in a fracture in material between the at least two grooves. | 01-23-2014 |
20120234538 | COMPOSITE FRAC BALL - Herein disclosed is a frac ball comprising three orthogonal axes x, y, and z; wherein the frac ball has approximately equal strength in each direction of the three axes x, y, and z. In an embodiment, the frac ball comprises a resin. In an embodiment, the frac ball comprises glass fibers or carbon fibers or both. In an embodiment, the frac ball comprises an equal amount of glass fibers in each direction of the x, y, and z axes. In an embodiment, the frac ball comprises glass fibers in the x and y axes and carbon fibers in the z axis. In an embodiment, the frac ball comprises no interlaminar layers. In an embodiment, the frac ball has different diameters. Also disclosed herein are methods of making and using such frac balls. | 09-20-2012 |
