Bottomhole Assembly (BHA) Components consist of varying tool types from: Stabilizers https://youtu.be/lw7uV7CFpws Stabilizers, by centralizing the drill string at selected points in the borehole, perform these important functions: They ensure that the weight of the drill collars is concentrated on the bit. They reduce torque and bending stresses in the …

A drill collar is a device used at the lowest part of a drill string, an important part of the bottom hole assembly (BHA). It is always a ...
