A high pressure injection flushing head includes a flushing body comprising an upper body portion, and a lower body portion coupled to the upper body portion. The upper body portion and the lower body portion cooperate to define a bore. A shaft is rotatably disposed at least partially within the bore. A plurality of rotary elements are configured to facilitate rotational movement of the shaft relative to the flushing body. The flushing body comprises a lubrication system having a plurality of grease nipples, and a network of pathways in fluid communication with the grease nipples that are configured to deliver grease to the rotary bearings. The flushing head couples to an adapter via a flanged connection so that the flushing head can be adapted for use with a plurality of drill rod types.

A covering for a rig structure has plural segments separably connected together to form a loop to enclose a portion of a rig structure. Segments can be added or removed to adjust the size of the covering. A lower edge of the covering is connected around a containment basin suspended from the rig structure to contain fluids captured by the covering. An upper edge of the covering is connected to an adjustable frame suspended from the rig structure. The frame can be raised after the covering is attached to it to tauten the covering.

Directional drilling technologies and methodologies involve/utilize a reamer embodying a pressure vessel configured for directing flows of fresh mud through the reamer/pressure vessel and toward an entry side of a bore hole being drilled by the reamer, facilitating single ream pass directional drilling of bore holes, and preventing the reamer from deviating from the path of the pilot hole.

A pipe installation device for a drilling rig includes a frame that is pivotably coupled to an elevated rig floor of the drilling rig, a saddle coupled to the frame and configured to grip a pipe, and a driver coupled to the frame and the elevated rig floor of the drilling rig. The driver is configured to cause the frame to pivot from a first configuration in which the saddle is configured to support the pipe in a substantially vertical orientation to a second configuration in which the saddle is configured to support the pipe in a substantially horizontal orientation for connection to a well device.

The invention relates to a drilling tool and a method for producing a bore in the ground, in which method ground material is carried away by a removal device on the underside of a main body of the drilling tool, flushing air is supplied by a feeding device into the bore, which is filled with drilling fluid, in the area of the removal device and ground material carried away by means of the flushing air is transported away through a discharge line. According to the invention, the ground material is transported to a receiving area in an upper section of the main body. A collecting hood is provided above the receiving area, which closes off the receiving area at the top, forming an air collecting space in which air collects. An outlet valve by means of which air is discharged from the air collecting space is arranged on the collecting hood.
