Abstract
In an embodiment, a work string for downhole use in a well comprises a safety valve comprising a sealable flow path; a first electrical connection disposed above the safety valve; a second electrical connection disposed below the safety valve; and a jumper electrically coupling the first electrical connection and the second electrical connection, wherein the jumper does not pass through the sealable flow path of the safety valve.
Claims
exact text as granted — not AI-modified1 . A work string for downhole use in a well comprising:
a safety valve comprising a sealable flow path; a first electrical connection disposed above the safety valve, wherein the first electrical connection comprises a first landing nipple; a second electrical connection disposed below the safety valve; and a jumper electrically coupling the first electrical connection and the second electrical connection, wherein the jumper does not pass through the sealable flow path of the safety valve.
2 . The work string of claim 1 , further comprising an electric submersible pump electrically coupled to the second electrical connection.
3 . The work string of claim of claim 2 , further comprising a pump landing disposed below the second electrical connection, wherein the electric submersible pump engages the pump landing.
4 . The work string of claim 1 , wherein the first electrical connection is electrically coupled to a power source above the first electrical connection.
5 . (canceled)
6 . The work string of claim 1 , wherein the first landing nipple comprises a first landing shoulder and a first latching indicator.
7 . The work string of claim 6 , further comprising a first latching mechanism that is electrically coupled to a surface of the well, wherein the first latching mechanism engages the first landing shoulder and the first latching indicator of the first landing nipple, and wherein the first latching mechanism is electrically coupled to the first electrical connection when the first latching mechanism engages the first landing nipple.
8 . The work string of claim 1 , wherein the second electrical connection comprises a second landing nipple.
9 . The work string of claim 8 , wherein the second landing nipple comprises a second landing shoulder and a second latching indicator.
10 . The work string of claim 9 , further comprising a second latching mechanism that is electrically coupled to an electric submersible pump, wherein the second latching mechanism engages the second landing shoulder and the second latching indicator of the second landing nipple, and wherein the second latching mechanism is electrically coupled to the second electrical connection when the second latching mechanism engages the second landing nipple.
11 . The work string of claim 1 , wherein the safety valve comprises a sealing element configured to substantially seal the sealable flow path in a closed configuration and allow flow through the sealable flow path in an open configuration.
12 . The work string of claim 11 , wherein the sealing element comprises a flapper for engaging a corresponding flapper seal, a ball for engaging a ball valve seat, a gate for engaging a gate valve seat, or a sleeve slidingly disposed within a window.
13 . A method comprising:
electrically coupling a first electrical connection with a second electrical connection in a work string disposed within a well, wherein the work string comprises:
a safety valve;
the first electrical connection disposed above the safety valve, wherein the first electrical connection comprises a first landing nipple, and wherein the method further comprising engaging a first latching mechanism with the first landing nipple, wherein the first latching mechanism is electrically coupled to a surface of the well;
the second electrical connection disposed below the safety valve; and
a jumper electrically coupling the first electrical connection and the second electrical connection, wherein the jumper does not pass through a sealable flow path of the safety valve, and wherein the second electrical connection is electrically coupled to a subsurface electric component; and
providing an electrical current to the first electrical connection.
14 . The method of claim 13 , wherein the subsurface electric component comprises an electric submersible pump.
15 . The method of claim of claim 14 , wherein the work string further comprises a landing disposed below the second electrical connection, and wherein the method further comprises engaging the subsurface electric component in the landing.
16 . (canceled)
17 . The method of claim 13 , wherein engaging the first latching mechanism with the first landing nipple comprises activating the first latching mechanism using a weight, an impact, a hydraulic mechanism, a longitudinal motion, a rotational motion, or any combination thereof.
18 . The method of claim 13 , wherein the second electrical connection comprises a second landing nipple, and wherein the method further comprising engaging a second latching mechanism with the second landing nipple, wherein the second latching mechanism is electrically coupled to the subsurface electric component.
19 . The method of claim 18 , wherein engaging the second latching mechanism with the second landing nipple comprises activating the second latching mechanism using a weight, an impact, a hydraulic mechanism, a longitudinal motion, a rotational motion, or any combination thereof.
20 . A method comprising:
producing a hydrocarbon from wellbore comprising a work string, wherein the work string comprises:
a safety valve comprising a sealable flow path;
a first electrical connection disposed above the safety valve, wherein the first electrical connection is electrically coupled to a power source and wherein the first electrical connection comprises a first landing nipple;
a second electrical connection disposed below the safety valve, wherein the second electrical connection is electrically coupled to an electric pump; and
a jumper electrically coupling the first electrical connection and the second electrical connection, wherein the jumper does not pass through the sealable flow path of the safety valve; and
isolating a first portion of the wellbore above the safety valve from a second portion of the wellbore below the safety valve using the sealable flow path.Join the waitlist — get patent alerts
