Thru-Tubing Technology

Hunting is able to offer unique benefits to the Thru-Tubing industry, providing advanced solutions for a wide range of Workover & Coiled Tubing interventions direct to service providers and operators alike.

Through examining customer needs, Hunting has provided many innovative and technical solutions such as the WellGripp Connector, designed to grip and seal on the outside diameter of coiled tubing. The spiral design of the slip spreads the radial load produced by axial loading, resulting in a connector with greater strength than conventional connectors and improved operating parameters.

With a proactive approach to the ever-increasing market demand for well-engineered solutions for on and offshore operations, Hunting does not merely provide tools & hardware.

This success has been built around knowledge of the industry, correct planning, reliability of the equipment and ability to react to client requirements through timely engineering service and teamwork.

Joints and Stems (back to top)

The Torque Thru Quick Connector is a self-aligning tool string connector, capable of withstanding high degrees of torque in both directions. It eliminates the problems of connecting the coiled tubing when there is no means of rotating either the tubing or the BHA.

(More)

The Torque Thru Knuckle Joint provides a full 15-degree angular deviation and internal pressure sealing throughout the full deviation of the tool. The ball and socket of the knuckle have keys that prevent rotation, while still allowing full angular movement.

(More)

The Pump Thru Swivel is a standard tool string component which when used, permits full rotation of the BHA made up below the joint.

(More)

The Hunting Downhole Filter is a simple tool that is run above any debris intolerant tool to ensure full operability.

Toolstring Stabilizers (back to top)

The Sleeve Stabiliser is used to centralise the coiled tubing BHA at points within the wellbore where problems of centralisation are paramount.

(More)

Nozzles (back to top)

The Bull Nose Jetting Nozzles are available in single or multiport designs.

(More)

The Variable Jetting Nozzle is a multi-ported sub for clean out, scale removal and other such jetting operations.

(More)

The Spincat family of tools provides a simple, self-rotating high-pressure jetting action for downhole tubulars. Maximised jet power is delivered to the tubing walls by rotational speed controlled by the viscous fluid governor. By using only a few rotating jets, this results in hard-hitting power.

(More)

Motors (back to top)

The WellDrill™ Downhole Motor incorporates industry leading power and bearing sections. Using specifically selected components based on realtime merit, this positive displacement motor produces optimum reliability and power output, with maximum efficiency for today’s Well Intervention thru tubing demands.

(More)

The Wireline Grab is used to fish broken wire from the tubing.

(More)

The Flow Release Overshot provides a means of engaging, locating and pulling on plain end fish or damaged external fishing necks.

(More)

To engage the fish, simply set down weight allowing the slip to collapse into the bore. When an overpull is applied, the slips will take hold of the fish.

(More)

The Impact Hammer is a device used to create impact in either an upward or downward direction in various operations.

(More)

The Hydraulic Intensifier is a straight pull-and-push intensifier tool, often referred to as an Accelerator. The tool stores energy until it’s released and can act as a shock absorber for shallow well applications.
