Update: Baker Hughes advises they are working on the bits now and hoping to have them completed in early April and sent out soon after that.
For the 2020 Drillbotics directional drilling challenge, a generic directional PDC micro-bit has been designed. The changes from last year’s design include increase of bit diameter from 1.25” to 1.5” and additional of fluid ports to a total of four. The bit features short bit length and high bit anisotropy. Most importantly, the bit has provision to let participants adjust the axial and side aggressiveness of the bit before a run by changing the exposure of the blunt tungsten carbide elements on the gage pads and on the bit face.
We encourage you to review the specs and learn how to use adjustable bits.
