| 221 | Method and apparatus for developing a surface well-drilling log | US47499474 | 1974-05-31 | US3916684A | 1975-11-04 | RUNDELL HERBERT A |
| Method or system for developing a surface drilling log indicative of one or more parameters of the formation being drilled. Measurements include the bit revolutions, the depth of the bit in the hole, the weight on the bit, and a determination of tooth dullness of the bit. The results are correlated to produce a parameter in accordance with a predetermined relationship of the measurements and the determination.

| An electronic supervisory control system is disclosed herein wherein rotary power, rotary speed, bit weight, hole size, penetration rate and mud weight ratio are utilized in conjunction with analog and electronic sensing means in order to afford drilling personnel a supervisory control system over drilling operation. Recorded information includes the rate of penetration, corrected d exponent and rotary torque, which may be visually recorded and electronically stored for use for both supervisory control and simultaneous understanding of the monitored drilling variables and their effect upon the drilling operation.

| 224 | Method for detecting roller bit bearing failure | US3581564D | 1969-05-14 | US3581564A | 1971-06-01 | YOUNG FARRILE S |
| A method for detecting failure of bearings in roller drill bits used in rotary drilling. Two drilling parameters-rotary torque and drilling rate-are measured and plotted with a third parameter ( psi ) equals ratio of the parameter of rotary torque divided by the parameter of drilling rate. A sharp increase in the third parameter psi indicates bearing failure.
