Drill bit basics The drilling bit industry is changing rapidly in the areas of manufacturing technology and the use of new materials. Computers have also caused dramatic changes in the drill-ing bit manufacture process, as today the use of bottomhole simulation software in order to have a new bit design “virtu-

Historically, bits and BHAs were chosen through a process of elimination. For a given drilling program, engineers first chose a bit based on offset well data. The amount and value of the data vary according to location, but of special interest to drillers are bit records that include bit type and design used, ROP, footage drilled per bit

The following are guidelines for drilled part design. ... resulting in a drill bit that is prone to wandering, chatter, and other instabilities. This problem can be solved by providing a fixture with a drill bushing close to the drill bit. However, part design must allow for this fixture, as shown below.

To understand design parameters for roller-cone bits, it is important to understand how roller-cone bits drill. Two types of drilling action take place at the bit. A crushing action takes place when weight applied to the bit forces inserts (or teeth) into the formation being drilled (WOB in Fig. 2 ).
