CT Jar Accelerators
The Toro Coiled Tubing (CT) Jar Accelerator
(CTA) impact tool is recommended whenever a
Toro CT Drilling Jar is placed in the string. The CT
Jar Accelerator tool operates with the jar
automatically, increasing reliability and ease of use,
while protecting the drillstring and surface
equipment from damaging shock waves. The CT Jar
Accelerator aids the drilling jar by maximize the
impact force of the drilling jar.
The Toro CT Jar Accelerator impact tool provides
maximum jarring impact in any hole profile. Used
in conjunction with the Toro CT Drilling Jar, the
CT Jar Accelerator tool combines the advantage of
jarring up, down, or up-and-down with hydraulic
fluid for maximum jarring impact. By increasing the
velocity of the mass applied to the jar, the CT Jar
Accelerator tool ensures optimum impact force
from the Toro CT Drilling Jar. When used with the
jar, fluid compression inside the CT Jar Accelerator
tool compensates for limited drillpipe stretch in
shallow or crooked holes, providing stored energy
so that the fish is hit hard regardless of depth.
The Toro CT Jar Accelerator impact tool also
optimizes jar performance in extended-reach,
directional, and horizontal wells, where the stored
energy in the drillpipe is lost because of hole drag.

The Toro CT Jar Accelerator is specifically
designed to be used in conjunction with the Toro
Coiled Tubing Drilling Jar (CTJ). In the event that
non-Toro equipment is used, Toro will not be
responsible for damages and/or failure that may
result.
