Abstract:
A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole.

Claim (Index 2):
A wellbore treatment assembly comprising:\n a fracturing valve for a downhole tool, the valve comprising a tubular having a through bore, the tubular being adapted to be connected in a tubing string, and the tubular having a window formed through the tubular, an outer sleeve disposed around the tubular, the outer sleeve having a port formed in a sidewall of the sleeve, the valve being arranged such that the tubular and the sleeve are axially moveable relative to one another from a first position in which the window and the port are aligned such that fluid in the through bore above the port can exit the valve through the aligned window and port and a second position in which fluid in the through bore above the port cannot exit the valve and the valve being further arranged such that movement from the first position to the second position can be made by applying a mechanical force to the tubular sufficient to move the tubular relative to the sleeve; a tubing string that can be manipulated from the surface into which the valve is connected such that the through bore of the tubular is fluidically continuous with a flow path of the tubing string; a lower seal below the fracturing valve configured to seal an annulus between the downhole tool and casing lining the wellbore; an upper seal above the fracturing valve configured to seal the annulus between the downhole tool and the casing; an equalization plug disposed on the tubing string below the window, the equalization plug being actuable between an open position in which fluid flow to the tubing string below the fracturing valve is enabled to a closed position in which fluid flow to the tubing string below the fracturing valve is prevented, wherein the actuation of the equalization plug from the open to the closed position can be effectuated by applying a mechanical force to the plug and actuation of the equalization plug from the open to the closed position effectuates movement of the fracturing valve from the second position to the first position.
