To clear the probing shaft. Comprised of an assembled spin set from a vented axle (6) with seals, coupled to an upper head (34) with an eyelet (41) and fluid input (40). From the threaded lower end (7) of the axle (6) to the fluid input (40), an inner fluid passage is formed in the device. After fixing the device to the coating column (R), the latter, after finding hindrances (O) on the oil/gas shaft (P) bottom in the shaft cementing phase, will be constantly rotated around the axle (7) by the chuck (MA) of the probing equipment simultaneously to the fluid injection (F). With the spin combined to the fluid combined to the fluid injection (F), the hindrance (O) in the shaft wall (P) shall be eroded and eliminated, allowing the passage of such coating column (R) to reach the bottom in the cementing phase.

A washpipe assembly includes a seal stack including at least one packing ring adapted to seal between a washpipe and the seal housing; a packing spacer ring adapted to maintain spacing between the seal housing and the washpipe, and a guide bushing ring positioned between the packing spacer ring and the washpipe. The guide bushing ring is made from a softer material than the wash pipe such that any contact therebetween will avoid damage to the washpipe. Additionally, the inclusion of the guide bushing ring may allow the packing spacer ring to be offset further from the washpipe than otherwise allowable.

The present invention provides an assembly, system, and method for an epicyclic washpipe swivel cartridge that can includes a gear reduction assembly with a sealed lubrication enclosure that can operate independent of roller bearings. The cartridge includes a pair of clamshell clamps to insert the cartridge in position without requiring dislocation of the mating assemblies. The system can further include a hydraulic port for efficient activation of the seals before placing high on a top drive of an oil derrick or other remote location.

A system for conveying proppant includes a conveyor assembly having a conveyor belt that receives proppant from one or more containers having proppant stored therein. The system also includes a conveyor auxiliary unit connected to an end of the conveyor assembly having one or more joints to enable expansion and collapse of the conveyor belt from the conveyor assembly. The system further includes a proppant chute to direct the proppant from the conveyor belt into a blending hopper, the proppant chute being positioned at a higher elevation than an inlet of the blending hopper.

A method includes drilling a first bore into a formation to a first depth, the bore having a bore wall and a first diameter that is sufficient to receive a casing pipe. A casing pipe is driven into the drill bore, the casing pipe having a binder on an exterior surface of the casing pipe that is configured to secure the casing pipe to the bore wall, the casing pipe being secured to an anchoring nut at a proximal end. The anchoring nut includes a gripping feature. An anchoring clamp of a drill rig is engaged with the gripping feature of the anchoring nut to thereby anchor the drill rig to the formation. The anchoring clamp includes a plurality of jaws that are movable toward and away from a central axis.

A system, method, and rotating control device (RCD) for monitoring a condition of a sealing element engageable with a body of the RCD. The system comprises a riser assembly, the RCD body, the sealing element, a latch assembly, a measurement device, and a controller. The RCD body is connectable with the riser assembly and the latch assembly is locatable in the RCD body and actuatable to expand the sealing element to engage the RCD body. The measurement device is operable to measure a parameter indicative of a condition of the sealing element. The controller is operable to analyze the parameter to identify the condition of the sealing element. The method for monitoring a condition of the sealing element comprises measuring the parameter indicative of the condition of the sealing element with the measurement device; and analyzing the parameter to identify the condition of the sealing element with the controller.

A drilling apparatus (1) is for use on a rotary drilling rig with a top drive which enables circulation and rotation of a drill string (3) to continue uninterrupted during the making of drill string connections. It has a snubber gripping mechanism (10, 9) to enable tool joints (2, 3) to be supported and gripped with a reduced pressure chamber (5) volume and snubbing force, during tool joint connections. The gripping mechanism has gripping pads (14) arranged to move radially by relative rotation of a drive cylinder (34) causing a tapered surface (36) of the drive cylinder (34) to press against or release the pad (14). A guide cylinder (30) supports and guides the pads (14) and collets (13) for retaining a drill string at an upset shoulder (19).
