PullSub™
Introduction
Independent engineering, guided by experience
PullSub™ is Kerr Downhole’s first technology concept and is designed to improve the effectiveness of stuck-pipe and stuck-object recovery.
In deviated wells, friction and side-loading along the drillstring can significantly limit axial force transfer to downhole jars. PullSub addresses this by improving load transfer efficiency at a critical point in the assembly, helping deliver more usable energy to the jar without altering standard operating practices.
How PullSub™ can help
Expanding options before escalation
The technology is applicable in both drilling and fishing assemblies and is currently under active development with patent protection filed.
