Drilling BHA Components and Design

Generally, the drilling bottom hole assembly (BHA) is one of the components of the Drilling String, which is below the Drill Pipes. The most common components of the BHA are drill collars, stabilizers, shock Absorbers, jars, reamers, heavy-weight drill pipes, and the drilling bit. The Bottom Hole Assembly BHA aims to drill a usable hole …

Drilling Jar Types, Calculations & Operation

Drilling jars are one of the BHA components that should be run with the drill string to help free stuck pipes. There are two common types of drilling jars: hydraulic and mechanical. Hydraulic jars use the pressure the string generates to apply an impact load. In contrast, the mechanical type uses a spring-loaded design to create an impact load. This …

Shock Absorber Sub In Drilling

A shock absorber sub or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses while drilling. It does this by converting the kinetic energy of the shock into another form of energy (typically heat), which is then dissipated. Most shock absorber subs are a form of dashpot (a damper that …

Drilling Reamer Types: Roller, Underreamer & Hole Opener

Drilling reamer types serve different bottomhole-assembly (BHA) purposes: maintaining hole gauge, conditioning irregular sections or enlarging a pilot hole. The main equipment families include roller reamers, fixed-diameter hole openers and expandable underreamers. A near-bit reamer describes where the tool is positioned; RFID describes one method of commanding a downhole reamer. These terms are not five …
