1. A method comprising:
correlating each of a plurality of test drill bits with stick-slip events, each of the plurality of test drill bits having a different design pattern comprising a combination of structural attributes, wherein said correlating comprises, for each of the plurality of test drill bits,
detecting variations in motion of the test drill bit during drilling operation;
detecting stick-slip based on the detected variations in motion of the test drill bit; and
in response to detecting stick-slip, recording a stick-slip event in association with the test drill bit;
determining a drilling efficiency value for each of the plurality of test drill bits;
correlating the determined drilling efficiency values with the stick-slip events to determine a threshold performance efficiency value, wherein the threshold performance efficiency value is a value above or below which bit induced stick-slip does not occur; and
selecting and constructing a drill bit having a design pattern based, at least in part, on the threshold performance efficiency value.
