The fully patented Drill-n-Ream (DNR) tool, the world’s first well bore conditioning system, is a dual-stage, eccentric reamer. DNR increases the well bore drift by 1/16” or 1/8” (customer choice) over bit size while rotating during horizontal and vertical drilling operations. The two reamer stages, spaced approximately five feet apart, act in unison to force the cutting structure into the formation while efficiently reducing ledges, doglegs, and well bore tortuosity.
Each reamer includes four blades with numerous PDC cutters designed in a progressive pattern to minimize torque. Diamond domes are also strategically placed to eliminate pipe damage and protect the PDC cutters while rotating in casing. The profile relief located near the blades entice the formation into the PDC cutting structure to maximize the amount of formation that is contacted while conditioning the well bore. Drill-n-Ream’s resulting conditioned well bore and drilling optimization will save you time and money.
Patented Features
1.Opposing eccentric reamers with pdc cutters force each other into the formation
2.Eccentric design enlarges bore hole drift to 1/16” or 1/8” over bit size
3.Progressive blades incrementally shear the formation
4.Diamond domes protect the pipe and pdc cutters when rotating in casing
5.Profile relief draws formation into pdc cutters more efficiently
