Abstract: A tool for both perforating a well casing in a hydrocarbon formation and for subsequently fracturing the formation. The tool allows not only perforation and fracking, but in a preferred embodiment allows both perforation of the casing and fracking of the formation without having to further reposition the tool within the wellbore. The tool comprises a cylindrical member having thereon an upper and lower seal member and a longitudinal bore therein, and a cooperating piston which operates a punch to perforate the well casing. A flushing port is provided immediately uphole of the upper seal member, which port when said tool is lowered downhole allows fluid flowing up a longitudinal channel to flush an annular region immediately uphole of said upper seal, thereby greatly reducing the incidence of sand impaction and thereby better allow the tool to be moved uphole for further perforation and fluid injection into the formation.

Abstract: A combined perforating and fracking tool, and method for using same, for perforating a hydrocarbon well casing and for subsequently fracturing the formation while maintaining the tool in situ. The combined perforating and fracking tool comprises, in a preferred embodiment, a series of connected cylinders arranged to be disposed in a well casing, each of the cylinders comprising a cooperating piston whereby a magnification of hydraulic force is generated. The series of pistons operate to actuate a punch assembly disposed at a downhole end of the series of connected cylinders to perforate the casing. A fluid injection port, in operation with at least one sealing member disposed at each end of the series of connected cylinders, allows fluid to be diverted into the formation through the perforations created in the well casing to induce fracturing in the formation.

Abstract: A combined system for treating an oil or gas well is provided which includes a truck, having a truck bed attached thereto and a fracturing support unit and an iron skid mounted on the truck bed. The fracturing support unit includes well head control equipment, and the iron skid includes a manifold having an arrangement of valves for controlling the flow of fluid to the well. The iron skid may be advantageously articulated off the truck bed and onto the ground for unloading the iron components used to treat the well.

Abstract: A three-in-one fracturing system is provided, which combines on a single trailer that can be pulled by a single tractor, a blending system for blending a fracturing fluid, a fluid pumping system for pumping the fracturing fluid into the well, and a data cabin for monitoring the operation of the blending system and the fluid pumping system.

Abstract: A tool for use in the treatment of a formation penetrated by a well bore. The tool comprises a tubular core having at least one opening therein for the discharge of pressurized fluid from within the core, first and second axially spaced apart seals disposed on the core for seals between the core and the well bore, the opening in the core being located between the first and second seals, and a third seal disposed downhole relative to the first and second seals for sealing between the tool and the well bore, the third seal protecting the first and second seals from pressure in the well bore below the tool.
