Title: Douglas James Brunskill: Innovator in Fracturing Technology

Introduction

Douglas James Brunskill is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of fracturing technology, holding a total of 4 patents. His innovative designs have advanced the efficiency and effectiveness of downhole tools used in the oil and gas industry.

Latest Patents

One of Brunskill's latest patents is a fracturing valve and fracturing tool string. This invention features a tubular mandrel with a through bore that is continuous with a tubing string, along with a frac window located on the side of the mandrel. An outer sleeve is radially positioned around the mandrel, which includes a sleeve port in its sidewall. The design allows the tubular mandrel to slide relative to the sleeve through the 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. Conversely, when the valve is open, fluid communication is enabled. This valve can be installed in a downhole tool equipped with a perforation device, allowing for versatile applications in isolating perforations both up and downhole.
