ABSTRACT A process for controlling proppant flowback after hydraulic fracturing operations has been developed and extensively field tested. In the procedure, fracture sand is coated with epoxy resin during the fracturing treatment. Unique wetting aids permit the rapid and complete epoxy resin coating of the sand while it is in the blender tub. Once placed in the fracture, the resin coated sand hardens to form a highly conductive, consolidated proppant bed which is resistant to flowback. Fluid residence times and mixing parameters required to obtain rapid resin coating of sand were studied utilizing a laboratory scale blender to simulate typical fluid rates and mixing energy. Fracture flow capacity and compressive strength development with respect to application parameters were determined. This paper presents results of field testing of this method and the development of metering and mixing equipment required to perform this process.
