Abstract: A self cleaning leak containment apparatus for an oil drilling rig includes nozzles to direct jets of cleaning fluid into the apparatus. The self cleaning leak containment apparatus can include a tray with nozzles fed by pumps that also serve to drain the tray. A sheet-form around the tray and draining into the tray can also have nozzles directed into it.

Abstract: There is a frame insulator that covers a window or door frame. A door or window has one or more panels that are supported by frame members. The frame members have interior surfaces and exterior surfaces. The one or more panels are mounted on the frame members. The interior surfaces or the exterior surfaces or both are enclosed by sheets of cross-linked polyethylene foam extending adjacent to the one or more panels and forming frame insulators.

Abstract: 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.

Abstract: A junk basket, comprising: mating parts, each mating part comprising an annulus covering portion, a cylindrical wall portion, a nipple seat portion and a nipple connector secured to the annulus covering portion, the cylindrical wall portion forming an interior wall to the annulus covering part; and the mating parts when mated forming an annulus covering surface, a nipple seat and a cylindrical wall forming an interior boundary to the annulus covering surface.

Abstract: A removable hand guard is provided for installation on drilling rig hand tongs and used to protect the hands of workers from being accidentally crushed when gripping the tong handle. The hand guard can include resilient body and tabs, which allow the guard to be positioned on the tong handle. The hand guard can be locked into place using locks and fasteners. The hand guard can include a slot, which can form a secondary handle to be used by a second worker to maneuver the tongs.

Abstract: Well fluid containment devices and methods. A housing may be provided for positioning around a pipe. A pipe gripping surface or grappler may be mounted to the housing. The pipe gripping surface resists movement when contacted in a first axial direction. The pipe gripping surface may permit movement when contacted in a second axial direction opposed to the first direction. The pipe gripping surface may, when contacted with a first force in a first axial direction, resist movement with an opposing force that increases as the first force increases. There may be a pressure relief connector between housing sections.

Abstract: A stabilizer for a pipe being removed from a well comprises a body formed of body segments where the body segments are separable to allow the body to open and be wrapped around the pipe. The stabilizer has a first annular seal formed by first seal elements within the body for receiving and stripping the pipe, and may have a second annular seal. The body segments may be hinged together about a hinge that may be configured to limit the movement of the body segments relative to each other. The hinge may comprise an interdigitated first and second row of fingers.

Abstract: A seal for replacement within a generally cylindrical passage of a supporting body has three or more overlapping sealing members arranged circumferentially around the passage in the supporting body and forming an annular seal around the pipe inserted into the passage. The sealing members are configured to accommodate an expansion of the pipe by moving to an expanded position by circumferential sliding contact of the sealing members along circumferentially slanted cuts between the sealing members.

Abstract: A pipe mat for use with a tubing tray for receiving, organizing and storing drill pipe tripped out of a drill string on a drilling rig has a plurality of substantially parallel and spaced-apart support rails to form a plurality of drain channels disposed between adjacent pair of support rails. A plurality of substantially parallel and spaced-apart nub rails is disposed on the plurality of support rails. The nub rails are substantially orthogonal to the support rails, thereby forming a lattice structure having openings disposed between the nub rails that are in communication with the drain channels. A plurality of spaced-apart pipe nubs extend upwardly from the nub rails, which hold a drill pipe in place when an end of the drill pipe is placed onto one of the pipe nubs. A method for collecting fluids draining from drill pipe uses the pipe mat with the tubing tray.

Abstract: An apparatus and method is provided for containing fluid or gas that is released when two adjoining sections of pipe are disconnected. The apparatus can comprise two or more arcuate sections hinged together to form a generally cylindrical or tubular containment chute that can be releasably enclosed around a pipe joint. Latching mechanisms can hold the apparatus around the pipe joint. The apparatus can have one or more sealing members at each end of the containment chute that engage the pipe above and below the pipe joint so that the pipe joint is completely enclosed and sealed off. A spout located on the sidewall of the apparatus allows fluid or gas that is released when the pipe joint is broken to flow from the apparatus through the spout into a hose connected to the spout, whereby the hose can divert the fluid or gas to a receptacle or container.

Abstract: A washing apparatus has a vacuum unit and a pressure washer unit. The vacuum unit has a mud tank, a first centrifuge, and a second centrifuge, and the pressure washer unit has a first water tank having a bottom, a top and a side, and a second water tank having a bottom, a top and a side. A frame having a top, a base and four corners supports the vacuum unit and pressure washer unit. The first centrifuge and the second centrifuge are fixed in respective first and second corners of the frame, and the first water tank and second water tank are fixed in respective third and fourth corners of the frame.
