Product Description

TCI Roller-Cone Drill Bits 
 

Product Description

Roller-cone bit design goals expect the bit to do the following:

• Function at a low cost per foot drilled.
• Have a long downhole life that minimizes requirements for tripping.
• Provide stable and vibration-free operation at the intended rotational speed and weight on bit (WOB).
• Cut gauge accurately throughout the life of the bit.

To achieve these goals, bit designers consider several factors. 

• The formation and drilling environment.
• Expected rotary speed.
• Expected weight on bit (WOB).
• Hydraulic arrangements.
• Anticipated wear rates from abrasion and impact.

Design focal points include:

• The bit body
• Cone configurations
• Cutting structures
• Metallurgical, tribological, and hydraulic considerations in engineering bit design solutions. (Tribology is a science that deals with the design, friction, wear, and lubrication of interacting surfaces in relative motion.)
