MITIGATING AND UNDERSTANDING STICK-SLIP IN UNCONVENTIONAL WELLS
Stick-slip is still present in most wells drilled today, especially in unconventional wells. Friction is an inevitable and important force along the long lateral section, but it contributes to many types of dysfunctions that lead to drilling inefficiency. Stick-slip is caused mainly by rotational friction induced along the drillstring, from the drill bit cutting the rock formation to the bottom hole assembly and drill pipe that contact the well bore.
