This invention refers to metallic protectors for threaded ends of pipe joints. Used for drilling of oil, gas and geothermal wells, which protect the threads and seals of the assemblys joints from impact during transportation, handling and maneuvering in the wells, and at the same time they eliminate the use of the cardboard washer which is only used during the delivery of the product, and being the seal exposed to impacts during maneuvering performed in the wells, and considering that the cardboard, when it deteriorates, does not provide the same protection against impact, as steel provides. |

| An apparatus for identifying oilfield equipment, including the maintenance of usage histories for the equipment and recommending whether the equipment is to be used in a prospective application based on prospective application and usage history. A portable encapsulated passive circuit (9) capable of transmitting an identification code is affixed to a piece of oilfield equipment (J). The circuit is activated by a portable reader (5) which receives and decodes the identification code and transmits it to a central computer. The central computer verifies the reader (5) and the existence of the equipment (J) in the database and retrieves the usage history for the equipment. Based on the usage history, the prospective application and guidelines for usage of equipment, the computer determines the advisability of using the equipment (J) in the prospective application and transmits the recommendation back to the portable reader (5). | ||||||

| 167 | Identification of hidden pipes etc. | EP90307550.5 | 1990-07-10 | EP0408320A3 | 1992-05-13 | Reeves, Anthony Vincent |
This invention relates to a system of identifying and providing information concerning hidden pipelines, cables, ducts, passages etc. In Figure 1 a pipeline 10 is located below ground level 11 and has on it an information containing element which is interrogatable, and is clipped into a recess 13. An alternative is to have the element in the form of an inertly packaged coded tag 12A attached to the pipe by straps. A transmitter/receiver 14 is connected by a flexible cable 15 to an antenna 16. The transmitter/receiver has a power supply 17 and display 18. Connected to the transmitter receiver 14 is a decoder 19 and a recorder 20. On interrogation, the interrogatable element 12 responds and returns a signal which is picked up by the antenna 16 and supplied to the transmitter receiver 14 where it is decoded and recorded and also displayed on the display 18. Information displayed may provide details as to depth and direction of alignment of the pipe 10, the material of which it is made, the fluid which is flowing through it, etc. |

| 169 | Method and apparatus for monitoring the integrity of coiled tubing | EP89202712.9 | 1989-10-27 | EP0377234A1 | 1990-07-11 | Mc Bride, Roger |
The onset of potential failure of a coiled tubing string is indicated by a diameter expansion or necking down of coiled tubing. The continuous monitoring of the diameter of the coiled tubing serves as a means and method for predicting the onset of such failure so that action can be taken to prevent failure prior to its occurrence. |

Fluid jet apparatus and method for cleaning material from the inside of a tubular conduit utilizing a cleaning head that lies adjacent to one wall of the conduit and includes at least two fluid jet forming means for directing a plurality of high pressure fluid cutting jets in a forward direction and at an acute angle relative to the axis of the head and the conduit so that they are directed toward the opposite wall of the conduit. The cleaning head is rotated around and remains adjacent to the wall of the conduit and is advanced into the conduit as the jets cut away the material whereby the fluid jets create an asymmetric cutting pattern on the surface of the material and the counter thrust of the fluid jets keeps the cleaning head offset relative to the axis of the conduit and against the wall of the conduit to provide passage for removal of the cut material and spent fluid away from the cutting area and out the end of conduit. |

| 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. | ||||||
| 175 | EMERGENCY DISCONNECT ISOLATION VALVE | US15767462 | 2016-10-12 | US20180298723A1 | 2018-10-18 | Bryce Elliott RANDLE |
| An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency. | ||||||

| Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid. | ||||||
| 177 | Pipe mat and method for using same for collecting fluids draining from drill pipe | US15619214 | 2017-06-09 | US10100585B2 | 2018-10-16 | Quinn A. J. Holtby; Dallas Laird Greenwood |
| 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. | ||||||

| A static push-the-bit rotary guiding device includes: a mandrel having a central passage, wherein a circumferential groove is provided on an outer wall of the mandrel; a sleeve, which is sleeved in the circumferential groove and able to rotate independently; and a clutch, for cutting off or transferring a power from the mandrel to the sleeve. When it is unnecessary for the static push-the-bit rotary guiding device to provide a deviating force in a steady inclined section, a vertical section and a horizontal section, a rotational inertia and an interior energy storage of the rotary guiding device are not decreased, which is beneficial to highly-efficient and stable drilling of a downstream drill bit. | ||||||
