DRILL COLLARS DESIGN AND CALCULATING WOB
|Weight On Bit|
Introduction To Weight On BitOne of the functions of Drill Collars is to provide Weight On Bit (WOB). The number of drill collars that are required to provide a desired weight on the Drilling Bit is usually based on buckling considerations in the Drilling Bottom Hole Assembly (BHA).
Our Drill Collar Design TargetBefore starting you should know that we have some targets here:
1- Determine the length of Drill Collars that we should be used to give us the required WOB
2- To determine if it is acceptable for you to keep some compression on HWDP
3- We don't want the buckling point to be in HWDP
