Anchor-Linear Actuator Tool
Measured, controlled pulling and pushing actions
Employ controlled, high-force linear actuation with high-expansion anchoring capability.
Jars are often used in fishing operations to free tools that become stuck downhole. A jar’s energy to free the “fish” comes from either stored energy in a cable of sufficient length, or a downhole accelerator. In horizontal wells or other wells with limited overpull, it may not be possible to apply enough force, or tension, to fire the jar using the cable.
