The TorkStar 50 is a hydraulically operated, horizontally mounted, continuously rotating headstock bucking unit. It has a spring centering tailstock with six self-centering clamp cylinders. The gear driven headstock is equipped with six self-centering clamp cylinders and a manifold to allow the hydraulic cylinders to clamp and hold a coupling so that it holds pressure while rotating.
The self-centering cylinders allow for quickly changing to different pipe sizes without the hassle of having to change the dies for every different size pipe.
The skid is fitted with hydraulic leveling jacks to quickly adjust the centerline of the unit for the different pipe sizes.
The TorkStar 50 is equipped with auto shift technology that allows the headstock to automatically change speed from high speed to low speed as the torque requirements go up. No manual shifting is required which minimizes operator error during the bucking process.
The hydraulic system is designed to run quieter to minimize in-plant noise levels and to run cooler even in the hottest climates. The TorkStar bucking unit is designed to be low maintenance to minimize maintenance costs. And the TorkStar 50 is compatible with many of the computerized torque logging systems to provide smooth connection torque graphs.
Both matrix and steel body materials are produced, depending on requirements for each application. Premium high-density spherical and crystalline carbides are used in hard facing of steel PDC bits and applied to the bit based on fluids dynamics mechanism.
Prime manufactures matrix products from 3 ¾” diameter, with steel products up to 26” in diameter and composed of high grade 4140 material.
Grades of cutters and geometries for soft to medium rock, laminated formations, abrasive sandstones and many other rock types are utilized in our bits, according to application requirements.
Our bits employ combinations of tungsten carbide and PDC gage materials. They can be delivered with any gage, from less than 1” up to typical RSS lengths. Options include passive, tapered, stepped, active and gageless.
Ideal for drilling a larger-than-nominal hole through standard casing ID. The expanded hole size results I higher quality cementing and logging operations and allows for restricted clearance casing diameters.
Eccentric Tool for Under Reaming Operations
The eccentric reamer is designed to drill an oversized hole, similar to bi-center bits.The Patented self-centering cutting structure provides an extremely durable and stable tool.
The eccentric reamer tools are commonly run behind RSS and MWD/LWD tools as a second
stage reamer, or can be coupled to a pilot bit to form a tool similar to a
bi-center bit. They are available in sizes up to 21” .
The concentric reamer are an extremely durable hole opener, with self-centering cutting structure and double row blade construction. It can be used as a hole opener to remove ledges and doglegs prior to running casing.
With PDC gauge and spiral blades, the concentric reamer delivers full diameter hole more consistently than conventional three-point tools.
With the concentric reaming tool, the pilot bit and the reamer are separate, allowing replacement of the
pilot bit. This pilot bit flexibility provides operators a wide range of drilling options:
• Standard PDC Bit
• Roller-cone Bit
Concentric reaming tools can also be run at different stages in the BHA.
