Introduction

Shawn Leggett is an accomplished inventor based in Okotoks, Canada. He has made significant contributions to the field of fracturing technology, holding 2 patents that showcase his innovative approach to downhole tools.

Latest Patents

Leggett's latest patents include a fracturing valve and a fracturing tool string. The fracturing valve comprises a tubular mandrel with a through bore that is continuous with a tubing string, featuring a frac window through the side of the mandrel. An outer sleeve is radially disposed around the tubular mandrel, which includes a sleeve port in its sidewall. The tubular mandrel can slide relative to the sleeve by applying and releasing 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. Conversely, when the valve is open, fluid communication from the tubing string is enabled. This valve can be installed in a downhole tool equipped with a perforation device. The tool string can be utilized with one sealing element while isolating lower perforations or with two sealing elements to allow pinpoint treatments that isolate perforations both up and downhole.
