HIGH TORQUE DRILLING DISCONNECT
The High Torque Disconnect uses a unique mechanism which eliminates the usual torque
dogs seen in most other disconnect assemblies. The disconnect was designed to with-
stand the vibration and torsional loading commonly associated with the use of downhole
motors and hammers, without disconnecting prematurely due to wear. The disconnect is
drop ball activated and incorporates a standard internal profile to facilitate retrieval of the
fish with the Specialty Tools Hydraulic Release Internal Pulling Tool. The tool is available
with customer specified connections.

HEAVY DUTY DISCONNECT
The Heavy Duty Disconnect uses torque dogs to counter any reactive torque generated
below the tool. This disconnect is drop ball activated and incorporates a standard internal
profile to facilitate retrieval of the fish with the Hydraulic Release Internal Pulling Tool. The
tool is available with customer specified connections.

PRESSURE RELEASE DISCONNECT
The Flow Release Disconnect provides all the benefits of the High Torque Drilling
Disconnect with the added advantage of not being drop ball activated. This
allows the disconnect to be used in conjunction with stiff wire line reels where the
coiled tubing string contains electric line which can prevent the passage of a drop ball.
The pressure activated time delay disconnect mechanism ensures that the disconnect can-
not be activated accidentally. The pressure at which the disconnect cycle begins
is adjustable from 1000 psi to 6000 psi. The delay timing of the disconnect cycle is
adjustable from 15 to 60 minutes.
