BHA Components consist of varying tool types from stabilizers, cross over subs, torque reducers, float subs, float valves, bull noses, z-bits, pony collars, and drill collars. These Bottom Hole Assmebly items are utilized in the drill string to achieve connection changes, regulate pressure, help guide the string, add or decrease the length between specific tool types, and generally add weight to the string.
Typical Application of BHA Components
In general, every drill string will utilize cross over subs, float subs, stabilizers, and some sort of collars. Specific applications will dictate if a certain BHA component is required, how many of each product, and where they are placed within the drill string. The drilling engineer or directional coordinator is usually responsible for assembling the BHA to meet the well bore’s specific needs.
