NavigatorThe NaviGATOR

Improves the probability of casings and liners reaching TD when rotation cannot be applied

The NaviGATOR™ is a casing-based tool that ratchets and rotates the end of a casing or liner string by reciprocating the pipe. A casing reamer shoe or guide shoe with an eccentric profiled nose can be placed below the tool so that the relative rotational motion from reciprocation can be used to orientate the nose over or past obstructions.

The tool, which can be used on cemented or un-cemented casing strings, completions, liners and sand control screens, is simple to install and improves the probability of casings, liners and other open hole deployed systems reaching planned TD.


TOP-CO TYPE 525 FLOAT COLLAR – TOP-FLOType 525 - Type 526


With the energy industry’s challenging and exacting performance requirements Top-Co’s 525 Float Collar and 526 Float Shoe have been designed to perform under the most severe downhole environments. Certified by Lloyd’s Register the Type 525 Collar & Type 526 Shoe meet API RP 10F Category IIIC specification. Manufactured from seamless casing grade steel (available in all grades), the float equipment features the open cage Top-Flo valve. TheTop-Flo valves combine a high flow area with temperature capabilities up to 400°F. The open cage design of the Top-Flo is optimized to allow for circulation of LCM (lost circulation material) while keeping the overall length of the float equipment relatively short.

Primary Application

The Top-Co Type 525/526 Float Collar & Shoe provide optimum performance under challenging conditions including; shallow wells, deep wells, extreme temperature and pressure ranges, sour gas and abrasive flow resistance. The 525/526 models are recommended for horizontal or deviated wells where low differential pressure may prevent sealing. The 525/526 system is a multi-purpose design that can be utilized in all applications from close tolerance liner to full casing string.


• API 10F tested to a III-C rating: 24 hours @ 10 bpm flow test, 5000psi back pressure at 400°F.
• Top-Flo one piece plunger design yields greater strength and
• The valve seal is a specially formulated oil resistant rubber for high temperature use with extreme wear resistance   properties and is positioned for protection from potential fluid flow damage.
• Plunger design prevents plunger rotation and erosion due to fluid flow.
• Valve throat protects the concrete from erosion.
• While under fluid flow spring is protected by the poppet.

GunDRILL ReamerGun Drill Reamer

Gun drilled boreholes while drilling

The GunDRILL™ Reamer is a versatile drilling reamer. This unique PDC-based reamer is the only one of its type on the market today, delivering accurately gauged and high quality wellbores. This tool can open boreholes in cases of severe swelling and/or borehole instability.

It provides reaming through a simple blade design that uses proprietary Tungsten Carbide Inserts (TCI) that give more reaming or stabilization according to the drilling and formation conditions and maintains the gauge for extended durations. TCI distribution is optimized to provide continuous reaming in longitudinal and radial directions. The Tercel PDC distribution works with our in-house cutter matrix design, resulting in balanced drilling and reduced vibrations. PDC gauge is passive, allowing it to interact with formation only when undergauge occurs.

The GunDRILL is highly flexible being uni-directional for applications where only back reaming is required and bi-directional for applications where front and back reaming is required. There is also the directional variant with flat TCIs for applications where sliding is expected. The tool can be made in steel and non-magnetic configurations to extend the flexibility of tool placement anywhere along the BHA.

Micro Core BitMicroCORE™

Geological insight while drilling faster

The MicroCORE™ Bit, developed in collaboration with TOTAL, is a revolutionary drill bit design that allows the continuous generation of micro-cores while drilling. The core, broken by the bit is carried to the surface up the annulus along with the drilled cuttings.

With operators looking to improve drilling efficiencies and geological insight through the analysis of larger formation samples, the MicroCORE Bit eliminates cutting in the central area where the cutting process efficiency is at its poorest. The generation of high quality undisturbed cuttings provides crucial geological information, giving operators the opportunity to analyze a continuous flow of valuable formation material while drilling faster.

The result is significant drilling performance improvements with ROP increases of up to 35%* and the generation of micro-cores from 5 to 30mm providing decision critical information without the cost of an additional run.

EzeeGLIDEREzee Glider Centralizer

Reduces torque and drag

The EzeeGLIDER® is a highly durable, wear resistant engineered polymer centralizer that reduces torque and drag and does not bind or jam as other metal products do. The tool has demonstrated field proven lower friction coefficients, leading to superior drag and rotational torque reduction and no requirement to rotate the completion assembly at any point during the operation.

Customer benefits of the tool, made from a high temperature high-pressure injection-molded engineered polymer, include reduced torque and drag and enhanced deployment and removal capabilities in ERD, highly deviated and horizontal well bore.

The EzeeGLIDER also extends well construction boundaries, increases the length of open hole completion to provide additional reservoir exposure/drainage and places forces where they are required instead of being lost in the form of drag.

Night Hawk Sealed Bearing MotorNightHAWK Series Sealed Bearing Motor

The Tercel NightHAWK Series Sealed Bearing Motor features the strongest driveline on the market today, allowing the operator to have a choice of any power section required to meet the drilling requirements.

The sealed pack ensures minimal pressure is applied to the oil chamber by dumping excess volume through a flow restrictor system strategically located mid tool. This is paired with a floating piston and extra seal grooves to reduce the likelihood of mud invasion preventing costly damage to the motor.

On and off bearings are custom made specifically to fit the Sealed Bearing Motor so maximum loads can be used while drilling, as well as robust radial bearings to build consistently without premature damage due to wear.
