IT Spiro-Torq® - Stuck Pipe Prevention Tool

The IT-SpiroTorq® is the optimum drilling tool for ensuring stuck pipe prevention. Whilst rotating down hole, the design simultaneously provides additional open hole cleaning by increasing the agitation of cuttings. In addition, the IT tool is a proven drill string tool joint wear protector and combats against differential sticking.

For just over 25 years, Rig Tech has been fully certified to supply our patented drilling technology to the Oil & Gas industry. Within this period, we’ve successfully helped several major operators reach complex drilling targets. At all times this has been achieved in a safe, timely and cost effective manner.

With an unrivaled track record, the IT Spiro-Torq Tool® has been successful in even the most challenging of well conditions:

• HP/HT Drilling
• Extended Reach Drilling
• Horizontal Drilling
• Geothermal Drilling
• Deep Water Drilling

Recommended for use in the open hole, the IT Tool is generally used for differential sticking / stuck pipe prevention. However it can be utilised solely as a tool joint wear protector or as a cuttings agitation / open hole cleaning tool.

For all cased hole drilling issues, please consider Rig Tech’s NRST (Non Rotating Sleeve Type) Spiro-Torq. Like the IT Tool, it offers a proven and trustworthy solution against drill string wear. In addition, the NRST Tool also reduces down hole torque and provides casing wear protection.

Stuck Pipe Prevention – how is this achieved?

Manufactured from one piece 4145 steel, the IT-SpiroTorq® is available with both API and premium connection types, ranging from NC38 to 7 5/8″ REG.

The specially grooved mandrel incorporates 4 fluted blades, with the contact area of each dressed with chromium alloy. The application of a pro-casing chromium alloy allows rotation in the casing, to address, for example, avalanche zones.

The fluted upset design increases the flow area of drill cuttings and assists with their agitation. This minimises the effect of E.C.D. and maximises the overall hole cleaning action. The design of the mandrel also provides flexibility and reduces the risk of cuttings pack-off.

The overall OD of the blades is slightly larger than the tool joint OD of the drill pipe. Down hole, this creates a stand off between the drill string and the formation wall. As only the face of the blades are in contact with the formation, the drill string is safe to rotate freely. Differential sticking / stuck pipe risks are therefore significantly reduced.

Each Spiro-Torq Tool is placed into the drill string as if they were a standard crossover sub. Placement is dependent on the severity of the drilling conditions, however as standard, a ratio of one tool per stand is normally required. Due to the simplicity of the tool’s make up procedure, existing rig crews are more than capable of placing the Spiro-Torq® Tool within the drill string. This removes the need for Rig Tech to supply costly service engineers, reducing both client cost and potential health and safety risks.

Free Torque and Drag Analysis

In addition to the supply of our Spiro-Torq Tools, Rig Tech also offer free torque and drag analysis. This is to determine placement and just how beneficial our tools can be under your own particular set of drilling conditions.
