Keeping in view the requirement of shallow to a medium depth well these models are available API-7K specification suitable for 27-½" Rotary Tables. The SSP (Square Drive Split Type) model are having a standard taper of Bowl No. 3 as per API to handle tubular size from 2.3/8” to 8.5/8”. This allows the use of extra-long SDXL slips required for a heavier load. Rise in taper by 2-½”, makes all slips rise by 2-½” which makes slip handling easier. This rise of slips distributes the load uniformly in the bushing resulting in less wear & tear of table bore. Additionally, this taper provides 50% more slip support resulting in better load managing capability. 27½” Master Bushing designed to handle string load up to 500 ton.

The JOTKB MODEL 27 PDHD OR 20 PDHD are developed for pin drive master bushing for rotary table sizes from 27-1/2" to 49-1/2" having 25-3/4" and 23" dia pin center. This unit is used for heavy duty drilling operations and high torque conditions on off shore as well as on shore drilling operations, and handle Kelly sizes from 3" to 6" Square or Hexagonal.

As the crew drills the well, the distances are calculated starting from the top of kelly bushing (refers to the sliding bushing located on the drilling rig floor on top of the rotary table that permits the drill kelly  to go down through it when the pipe is turning and the hole is drilled.

Once the casing pipe is permanently cemented into the hole (or set) and either the braiden head or wellhead installed, the measurements from the top of the wellhead to the top of the kelly bushing are calculated and subtracted from all drilling records. This allows precise well records for once the drilling rig is no longer there.
