Flex Drill Collar


The section of the bottomhole assembly (BHA) that provides the most weight on bit is the drill collar. This component of the BHA is thick walled pipe and is the heaviest section of the drill string. Flex Drill Collars are used in directional applications where the drill collar will be subject to higher bending stresses. When running MWD/LWD tools, Non-Magnetic Drill collars are run so they won't interfere with the drilling tools electronics.
