Multiple Specifications of Wireline Drill Rod Pipe Casing. A key aspect in determining the depth capacity of drill rods could be the casing. Casing protects the well from abnormal subsurface formations that may contaminate the drilling fluids and affect the bottom layers of the well.

Steel tubes used as wireline drill rods (WLDR) require tight dimensional tolerances. They need to have smooth connections, as well as concentricity and straightness.

WL Casing

WL casing is a tubing set inside the well to protect subsurface formations and withstand the pressures and temperatures experienced during drilling. While drilling, it protects the rock walls for the well from collapsing and withstands water from being contaminated through the drill mud. Casing pipes are very different than drill pipes and must meet API5D specifications.

Made with a double-butt tapered joint and sparse thread, this pipe provides superior strength HDD drill pipe with an load capacity that is optimized. Its high tensile and internal pressure ratings make sure that the tubing can withstand the forces associated with drilling operation.

In addition, this pipe’s low profile allows for a more efficient and cost-effective installation. Its OD that is slim bypasses restrictions that limit the accessibility associated with the safety valve, which makes it much easier to access and re-open. A current deployment associated with ReLine WL on a Gulf of Mexico well used to remediate a flapper that is plugged saved 8 hours of rig time.

D Casing

UEW manufactures and supplies induction hardened wireline HWT casing/rod for diamond core drilling. Most of the rods are induction through hardened on both ends upto a length of 10 inches. This can help in reducing the torque that is unwanted replacing area of the drill collar. It also improves the load capacity associated with drill string in directional wells.

Patented XQ threads engage smoothly with innovative geometry that is self-aligning decreased wedging and jamming. This load that is symmetrical increases load capacity significantly when compared with traditional API connections.

Most rotary drill rigs have API or modified API connections with relatively large wall thickness. This enables them to tolerate a certain level of misalignment during make-up and break-out. In comparison, wireline threads have quite thin wall and cannot tolerate any misalignment at all during these operations. This misalignment damages the threads and decreases the strain bearing capacity associated with rod joint. Therefore, it is crucial to make use of a hands free rod handling system that ensures diamond core barrel that all the joints in the drill rod are properly made up ahead of the hammer is released by the mechanical loading arm.

WT Casing

Casing spacers allow for faster and more drilling that is accurate resulting in reduced operating costs. They also eliminate the dependence on annulus filler, which requires labor that is intensive can act as an electrolyte allowing unwanted current to go into the pipe.

WT casing is made on DCDMA C80 tubing and a tapered HD thread that works well under difficult drilling conditions. It offers increased strength and it is made for repeated use. The double-butt joint and thread that is sparse torque efficiency, lightens friction and reduces labor costs.

UEW induction hardened wireline drill rods are manufactured using state-of-the-art equipment at our manufacturing unit in Canada. They feature heat treated tool joints, hardened gauges and CNC machined components for improved strength, accuracy and durability. The induction hardened core is abrasion resistant and it is lubricated with a high quality rod grease to cut back friction. The premium connections are really easy to use and reduce the sheer number of crew members on the drill floor, lowering operational expenses while increasing safety.

LongyearTM Casing

Boart LongyearTM offers a range that is full of casing in both W and WD threads. The company is also well recognized for the q that is patented RQ drill rods, which feature self-aligning double-start thread joints which are an easy task to make and break. The XQ rods are stronger and stay longer than standard casing, and they provide a balanced load response with BWcasing pipe for less box bulging.

A carbide that is tungsten protection system prevents excessive wear in the rod’s outer diameter in abrasive conditions and helps free the bit when drilling through unconsolidated formations such as for instance cobbles, boulders and heaving sands.  It may prevent over-tightening of this drill pipe by providing another surface that is cutting.

Swivel installed

A swivel installed on the conductor pipe provides a outlet that is convenient casing cuttings to be diverted into a group system or cyclone. In addition, a mud discharge swivel can be used to divert the drill and mud cuttings away from the hole.
