    Drilling mechanics and performance - IADC

    teeth of a more aggressive roller cone bit are aligned to stay on bottom and engaged for a greater distance in the rock, so they remove more rock volume per minute. The expected responses to WOB are shown in Figures DP-2a, -2b and -2c. If the bit is efficient, a plot of ROP vs WOB will form a straight line, regardless of rock strength, bit cut-

    Roller Cone Bits – petrolimak

    Roller cone bits have conical cutters or cones with steel teeth or tungsten carbide buttons around them. As the drill string is rotated, the bit cones roll along the bottom of the borehole in a circular motion. As they roll, new teeth come in contact with the bottom of the hole, chipping the formation below and around the bit tooth. Air or drilling fluid lift the crushed rock chips from the ...
