At the Core of Drilling
Supporting Equipment
Beyond our flagship technologies, we stock the supporting infrastructure to overcome complex downhole challenges.
From sub-assemblies to pressure control and handling equipment, our inventory is ready when you are.
Drill Collars
Non-Magnetic Slick Drill Collar
Neutralizes magnetic interference near the poles, with strength and hardness for standard drill string tools.
Non-Magnetic Spiral Drill Collar
Spiral grooves reduce differential sticking while neutralizing magnetic interference for accurate directional drilling near the poles.
Steel Drill Collar
Adds weight to the bit and stiffness to the BHA, manufactured from heat-treated 4145H modified alloy steel.
Drill Pipe and Heavy-Weight
Tubing
Smaller-diameter tubulars for workover and completion, available in PH-6/CS types with thread sizes from 2⅜ to 4½ inch.
Tubular Drifts
Drift gauges that verify minimum-diameter specifications on casing and tubulars, available in Teflon, steel, and aluminium.
Hole Openers
Devil Drill - Bladed Hole Opener
Tungsten-carbide-dressed blades enlarge the wellbore where roller cones aren't needed, with jets for effective hole cleaning.
Security Type Hole Opener
Fixed-diameter enlargement for pilot holes and clean-out runs, with hard-faced cutters that swap out quickly.
Stabilizers
ClearPath™ Nearbit Stabilizer
Maximizes stability at the bit and minimizes bit whirl, with dome-shaped blades for reduced torque and drag.
ClearPath™ Bitbox Stabilizer
Positioned directly above the bit to improve stability and weight transfer, without compromising steerability or torque.
Integral Blade Spiral String Stabilizer
One-piece milled stabilizer for rotating applications, with a 270-degree wrap and high total flow area.
Integral Blade Near Bit Stabilizer
Run only at the bit, with box connections both ends and a bore for float.
Integral Blade Autotrac Stabilizer
Medium crown length and shorter taper angles for directional and horizontal applications, with hardfaced blades.
Integral Blade Nortrac Stabilizer
Straight blades maintain directional control during sliding operations, with medium-to-high flow area and hardfaced edges.
Integral Blade D-Trac Stabilizer
Tight spiral blades reduce vibration and torque, extending downhole tool life on MWD, LWD, and RSS.
Sleeve Type Stabilizers
One-piece mandrel with interchangeable sleeves, swapped out quickly on the rig floor and discarded when worn.
Welded Blade String Stabilizers
Straight-bladed, high-strength 4145 steel body for large diameter holes, hardfaced for extended tool life.
Sub-Assemblies
Float Subs
House the float valve within the BHA, controlling fluid flow and preventing cuttings from plugging the bit jets.
Filter Subs
House retrievable or non-retrievable mud screens, including Diffuser blade technology, to filter drilling fluid downhole.
Pup Joints
Short tubulars for spacing-specific drilling operations, ordered with tapered or square shoulders and thread protectors.
Circulating Subs
Integral, one-piece pin or box connection subs featuring a WECO figure 1502 union for pump-in operations.
UBHO and Muleshoe Subs
Run below a non-mag collar with an oriented landing sleeve for directional survey equipment or motors.
Side-Entry Subs
Single or double port, one-piece design tested to 1.5 times safe working pressure for specialized pumping.
Saver Subs
Sacrificial connections that protect the Kelly or top drive from repeated wear, easily repaired or replaced.
Crossover and Bit Subs
Adapt varying drill string connection sizes, from drill pipe to collars or collars to collars.
Lift Subs
Flow-through or conventional design with a machined elevator recess, built for handling long or heavy BHA components.
Handling Tools
Elevators
Hinged clamps that lift and lower drill pipe, casing, and tubing, available in bottleneck, slimhole, and slip type.
Becket and Bails Assembly
Lifting rods with eyes on both ends, connecting the traveling block to the elevators.
Bowl and Slip
Cylindrical insert bowls with a tapered inner surface, supporting slips across various casing sizes.
Slips
Hinged metal wedges that grip the drill string, forming a circular hold around pipe, casing, or tubing.
Tongs
Manual tools for turning drill pipe and casing, including HT-200 rotary, type-C, and Kelco type tongs.
Stabbing Guides
Reduce damage to connections during alignment of tubing and drill pipe, available in different styles.
Safety Clamps
Flexibly hinged links with tapered slips that grip the pipe, protecting against slippage under load.
BOPs
Blowout Preventors (BOPs)
National Oilwell Varco and Shaffer units for shutting down flow during an uncontrolled kick.
Rams
Pipe, blind, and shear rams sized to match blowout preventer stacks for well control.
BOP Tandem Boosters
Add shearing force to blowout preventer stacks for critical well-control scenarios.
BOP Shear Bonnets
Structural housings supporting high-capacity shear rams on the BOP stack.
BOP Operating Hoses
Fire-retardant and steel-flex lines connecting BOP control systems to the stack.
Accumulators
Diesel, electric, and air-powered hydraulic units for actuating blowout preventers.
Gate Valves
Manual, hydraulic, and air-actuated valves for controlling fluid and well pressure.
