Electric Submersible Pump (ESP) Rig Less Deployment Method and System for Oil Wells and the like
A deployment system as a rig less docking station with an inline male wet mate-able connectors and power cable and a motor connector with inline female wet mate-able connectors coupled to an electric submersible pump (ESP), the docking station is at the bottom of a string of production tubing and remains in the well for the life of the system while the motor connector is mated to an ESP and lowered into the well by wireline or other suitable deployment method. The rig less deployment system has a lower initial cost, larger through-bore, improved debris tolerance, and the ability for pump-assisted installation and retrieval techniques. Both the moveable female and the static male connector are pressure balanced for temperature and volume variation and the male connector utilizes a heavy dielectric fluid in a reverse labyrinth design to isolate borehole fluid from the electrical connection.
Downhole disconnect tool
A system can include a disconnect tool connected as part of a tubular string, the disconnect tool including an outer housing, and an inner mandrel in the outer housing, in which an abrasive slurry is directed to flow through the tubular string and from the inner mandrel to an annulus between the inner mandrel and the outer housing, and the abrasive slurry erodes through the outer housing. A method can include installing a tubular string in a well, then deploying a disconnect assembly into the tubular string, and flowing an abrasive slurry through the disconnect assembly, thereby parting the tubular string. A disconnect tool can include a rotational flow structure configured to induce rotational flow, and an inner diameter decrease downstream of the rotational flow structure.
Wireline Release System
A wireline release system may include, but is not limited to: a first housing including an internal body portion defining at least one bore; a second housing operably couplable to the first housing; a wireline tie-off assembly, operably couplable to a wireline cable, disposed at least partially within the bore; an assembly disposed at least partially within the bore; a first mechanical weak point configured to maintain the wireline tie-off assembly at a first position of the bore; and a second mechanical weak point configured to maintain the assembly at a second position of the bore.
DOWNHOLE ELECTRICAL CONDUCTOR MOVEMENT ARRESTOR
Provided, in one aspect, is a connection module. The connection module, in one aspect, includes a cable segment housing, a conductor extending into the cable segment housing, and a movement arrestor substantially surrounding the conductor and axially fixing the conductor relative to the housing, the movement arrestor having a non-PEEK non-conductive portion.
Electrical wet connection between LWD/MWD tools with longitudinal and rotational degree of freedom and pressure protection eliminating vibration and shock effects
Electrical wet connection (EWC) with multiple power and communication lines for connecting Logging While Drilling tools (LWD) and/or Measurement While Drilling tools (MWD) is described. The contacts between the modules may be made by, for example, using pressure bulkheads to ensure protection of the tools if the pressure protection is reduced or lost. The contacts may be locked together in a convenient manner to eliminate downhole vibrations and/or shocks. The may make the signal transmission quality approaching, as good as, or even better than wireline tools. The connection may be sealed from the well muds under high pressure and this protection may be enhanced such as by doubling or even tripling for extreme reliability in difficult environments. The designs described herein may advantageously allow for a large amount in collar lengths to be compensated and/or provide two degrees of freedom-rotational and/or may be longitudinal for ready connection on the well site.
Environmental sensing wireline standoff
The use of an environmental sensing wireline standoff may improve operations during borehole logging procedures. An environmental sensing wireline standoff may comprise a lower body, an upper body, and a cable insert. The cable insert may further comprise a first segment and a second segment, wherein the cable insert is disposed between the lower body and the upper body, and wherein the cable insert is configurable to clamp directly onto a wireline cable. The environmental sensing wireline standoff may further comprise a sensor package. A method of assembling an environmental sensing wireline standoff may comprise securing a first segment of a cable insert into a lower body, securing a second segment of the cable insert into an upper body, attaching the sensor package to the upper body, and securing the lower body to the upper body.
Cable guard for securing cables to downhole systems
An improved cable guard and methods of use are provided for securing an MLE cable to an ESP system in a wellbore casing, the system having flange bolts and an annular channel. The cable guard may be unitary (i.e., one piece), comprising a body having a bridge portion and two side portions forming a cavity for securing the cable to the system, two connectors extending from the side portions, each connector forming at least one aperture for receiving a flange bolt, and skids extending from the side portions for guiding movement of the system within the casing. In some embodiments, methods of using the improved cable guard may comprise providing the cable guard, positioning the cable guard to receive the cable within the cavity and to receive at least one flange bolt within an aperture, and securing the cable guard to the system.
PORT AND SNORKEL FOR SENSOR ARRAY
An array of sensors provided on the outside of a tubular string for measuring a property within the tubular string. The array of sensors may include a plurality of connected sensors, wherein at least one of the plurality of connected sensors is at least partially encompassed in a shroud. A snorkel line may extend from the shroud, the snorkel line capable of coupling with a sensor port in a tubular of the tubular string. The snorkel line may establish fluid communication between one of the sensors at least partially encompassed in the shroud and a corresponding sensor port of a tubular in the tubular string.
Systems and Methods for Bonding a Downhole Tool to a Borehole Tubular
A method for bonding a first downhole tool to a borehole tubular. The method may include applying solder particles, each particle having an outer shell and a core of liquid metal, to at least one of a surface of the first downhole tool or a surface of the borehole tubular. The method may also include rupturing the shells of the solder particles to release the liquid metal cores. The method may further include bonding the first downhole tool to the borehole tubular by allowing the released liquid metal core to solidify.
Tubing hanger alignment device
Systems and methods for landing a tubing hanger in a wellhead and then orienting a tubular housing (e.g., tree, spool, or flowline connection body) relative to the tubing hanger while landing the tubular housing on the wellhead are provided. The systems may include a tubing hanger alignment device, wherein the tubing hanger alignment device includes one or more hydraulic, electric, or fiber optic lines extending therethrough and one or more couplings disposed on a lower end thereof. The tubing hanger alignment device is configured to couple one or more hydraulic, electric, or fiber optic lines on the tubular housing with one or more hydraulic, electric, or fiber optic couplings on the tubing hanger during landing of the tubular housing onto the wellhead regardless of a relative orientation of the tubing hanger and the tubular housing with respect to the wellhead.
