Open Hole
Whether facilitating access in tight logging conditions or generating downhole impact forces to free stuck tools, Impact Selector's range of open hole wireline toolstring accessories add significant value to our client's operations.
Electronic actuation system to determine activation force anywhere between upper and lower limits.
Spring-assisted relatching mechanism does not rely on tool weight to relatch the jar.
Externally accessible and easy to use adjustment of upper and lower activation thresholds.
Full electrical pass through to the wireline tool string below.
Reverts to fail-safe mechanical mode in the event of power or telemetry loss.
Impact Selector specialist recommended to run / maintain the tool.
Jarring on command under any line tension greatly enhances operational flexibility.

Impact Selector specialist recommended to run / maintain the tool.
Helps prevent stuck or lost tool strings by providing precise downhole impacts.
Single tool design does not need additional tools to enhance the operation.
Provides multiple run and activation capability. Uses fully mechanical operation.
No critical time delays or concerns with pressure and temperature.
Ability to relatch immediately under the jar’s own weight by simply decreasing line tension.
Remote calibration possible with Impact Selector’s portable calibration tester.
Fully adjustable on the surface while in the tool string.
Short and compact design keeps rig ups as short as possible.
Instant and unlimited activations with no waiting period once the pre-set is reached.
Resets down hole immediately under its own weight for unlimited activation cycles.
Pressure and temperature compensation system with mechanical components isolated from wellbore fluids.
Maintenance can be performed in the field within a confined space by a certified technician.
Maintenance can be performed in the field within a confined space by a certified technician.
Compact design does not require auxiliary tools to enhance impact force or duration.
Friction ring design makes it easy to install anywhere on the tool string.
Tungsten carbide surface provides protection from wear.
Maintains stand off during wireline logging operations.
The Friction Ring attachment mechanism secures to the toolstring while allowing the standoff to swivel.
Robust and long lasting construction.
Use of multiple fins to reduce tool string contact with the wellbore wall.
Lifting force placed at a tangent reduces contact with the bore wall.
Creates standoff which significantly reduces abnormal contact friction.
