  • This disclosure describes an artificial lift string that allows for easy retrieval and repair of artificial lift systems, such as electric submersible pumps.

  • the electric and/or hydraulic lines power, control and/or lubrication to the artificial lift string.
  • FIG. 1 is a side, half cross-sectional view of an example downhole artificial lift system 100a.
  • the artificial lift system 100a includes an artificial lift string 102 within a wellbore 104.
  • the artificial lift string 102 operates fully submersed in production fluid, assisting in flowing production fluid from a production zone 106, up through production tubing 108, to a topside facility, such as a wellhead 110.
  • the topside facility includes a land based or subsea wellhead.
  • a cable 116 such as a wireline, slickline, e-line or other type of cable, supports the artificial lift string.
  • the cable 116 supports the weight of artificial lift string 102 during deployment.
  • the cable 116 includes a smooth outer surface such that the cable can be fed through a lubricator or similar structure. Electric and/or hydraulic lines to operate the artificial lift string can be incorporated with and/or separate from the cable 116.
  • an interconnect 114 At an uphole end of the artificial lift string 102 is an interconnect 114.
  • the interconnect 114 allows for the cable 116 extending between the wellhead 110 and the artificial lift string 102 to be released at an uphole end of the artificial lift string 102 while the string 102 is downhole.
  • the artificial lift string 102 is stabbed into a downhole receptacle 118 in the production tubing 108.
  • the downhole receptacle 118 can include a polished bore receptacle, a packer configured to receive the artificial lift string 102, or any other receptacle that is appropriate for the operations described herein.
  • the artificial lift string 102 and the downhole receptacle 118 seal against one another when the artificial lift string is fully received by the downhole receptacle 118. That is.
  • the downhole receptacle 118 includes a latch configured to secure and retain the artificial lift string 102 within the downhole receptacle 118. Such latches are described in greater detail later within this disclosure.
  • the interconnect 114 is configured to enable a safe release of the artificial lift string 102 from its cable 116 to facilitate easy retrieval of both the cable 116 and the string 102 in two trips such that there is no lost time due to fishing the string 102 or any aspect thereof from the production tubing 108.
  • the interconnect 114 is helpful where the cable 116 strength itself is marginal over that required to retrieve, i.e., lift, the artificial lift string 102 after it has been deployed and then needs to be removed.
  • the mechanism of release of the interconnect 114 can be a shear to release mechanism, with a tension member(s) being tied to a shear sub of the interconnect 114 that could be set to a given value with high precision using either shear pins, bolts or studs; the subsequent working members of the cable (electrical conductors, hydraulic lines, data cable) would progressively release in sequence at a substantially lower value via a specialized splice with a known pull to failure value.

  • An electric mechanism could actuate a rotational mechanism that allowed free axial travel to facilitate shear mechanisms to engage or could provide the shearing force.
  • Another embodiment would use an electrical signal to actuate a perforating charge that would sever the interconnect 114.
  • Yet another embodiment could use a simple electronic release mechanism where there was a mechanical coupling or latch that is defeated with an appropriate signal.
  • each of the abovedescribed types of active interconnect 114 configurations could have a mechanical release as a backup in the case of an interruption in electric or hydraulic communication that defeats these active methods.
  • an electric or hydraulic system could be coupled with the mechanical system.
  • Some embodiments can include three or more of the above described release mechanisms for tertiary’ redundancy.

  • the cable 116 is released via the interconnect 114 at the electric submersible artificial lift string 102.
  • the interconnect is released by an over-pull of the cable 116 from the wellhead or topside facility 7 . Once the cable 116 is released, it is recovered from the wellbore 104.
  • a fishing or running tool (not shown) is run into the wellbore 104 on wireline or tubing and received by the artificial lift string 102.
  • the tool grips and pulls up the artificial lift string 102 so it can be retrieved from the wellbore 104.
  • the tool performs an overpull to release the artificial lift string 102 from the latch of the receptacle.
  • a jarring tool is used to release the artificial lift string 102 from the latch of the receptacle.

  • FIG. 11 shows an alternate alternative artificial lift string 1102 that is similar to the artificial lift string 202 discussed above, except as noted below.
  • the artificial lift string 1102 need not land in a receptacle 118 in the production tubing 108, but instead has a packer 1140 configured to seal and grip the interior of the production tubing 108.
  • the packer 1140 can be mechanically actuated and released, for example, via by manipulation of the string 1102 and/or it can be hydraulically and/or electrically actuated via a control signal supplied through the cable 116.
  • the lines 218 are shown traversing the exterior of the housing 204.
  • the string 202 includes a safety valve 1150 configured to shut in the flow through the production tubing 108 upon failure of the artificial lift string 1102.
  • a safety valve 1150 configured to shut in the flow through the production tubing 108 upon failure of the artificial lift string 1102.

Abstract

Une colonne de relevage artificielle (102) comporte une extrémité côté fluide qui est couplée à un moteur électrique et conçue pour être entraînée par celui-ci. Un dispositif d'interconnexion (114) se trouve au niveau d'une extrémité côté supérieur de la colonne de relevage artificielle Le dispositif d'interconnexion est conçu pour relâcher un câble (116) entre la colonne et une installation en surface (110).
