AfterShock™

Introduction

Independent engineering, guided by experience

AfterShock™ is a flow-activated downhole impact technology developed to reduce extraction forces in cased-hole intervention and abandonment operations. It is designed to condition bonded tubulars by applying controlled radial energy into the casing wall, helping to weaken cement bonds and mobilise trapped solids at critical locations. The technology is intended to expand the decision space between conventional pulling and more invasive escalation methods.

How AfterShock™ can help

Expanding options before escalation

Unlike existing solutions, AfterShock operates using pumping alone and does not require workstring rotation or casing deformation to function. This makes it inherently compatible with fishing and intervention bottom-hole assemblies, allowing it to be deployed above spears, overshots, and cutting tools while axial load is applied from surface. The result is a simpler, more flexible approach to conditioning stuck or cemented tubulars in complex wellbore environments.

AfterShock is being developed with a primary focus on plug and abandonment, slot recovery, and cased-hole fishing applications. Its architecture is intended to support targeted treatment at known problem zones, as well as staged conditioning over longer intervals through controlled tripping. The technology is currently under patent protection and is progressing toward prototype development and field evaluation.
