Patent abstract
A logging plug is disclosed having an internal sealing mechanism therein which provides a high degree of sealing integrity between the bore of the plug and a coiled tubing or other means of suspending wellbore equipment running therethrough. The sealing mechanism utilizes a combination of low friction, elastomerically-energized cap seals and ring seals to ensure that the sealing surfaces adapt continuously to the changing profile of the coiled tubing to provide a true dynamic seal around the coiled tubing.
