Eccentric Dog Leg Reamer


The Eccentric Dog Leg Reamer (EDLR) is a drilling tool used to condition the borehole by removing ledges and micro-ledges. These ledges can lead to increased Torque and Drag which leads to wasted energy and decreased efficiency. The tool is designed to have high and low-pressure systems around the tool which break up cuttings dunes. This process results in a cleaner wellbore and increased drilling efficiency.


  • Vortices around tool force cuttings dunes to break and migrate up to the surface
  • Keeps wellbore free of excess cuttings, ledges, and rough sections
  • Allows lateral sections to be drilled out further
  • Reduced possibility of packing off and lost circulation
