Patent attributes
Systems and methods are disclosed for selecting a drill bit design that reduces or eliminates bit induced stick-slip. In some embodiments, each of a set of test drill bits is correlated with stick-slip events, wherein each of the test drill bits has a different design pattern comprising a combination of structural attributes. The design pattern stick-slip correlation includes, for each of the test drill bits, detecting variations in motion of the test drill bit during drilling operation. Stick-slip for each of the test drill bits is detected based on the detected variations in motion of the test drill bits during operation. The correlation further includes in response to detecting stick-slip, recording a stick-slip event in association with the corresponding test drill bit. The method further includes determining a performance efficiency value for each of the plurality of test drill bits and correlating the determined performance efficiency values with the stick-slip events to determine a threshold performance efficiency value. A design pattern for a drill bit is selecting or determined based, at least in part, on the threshold performance efficiency value.
