## Abstract

A method for providing well safety control in a remedial electronic submersible pump (ESP) application including a making up an electric submersible pump (ESP) on a conduit with a primary well control capability; running the foregoing through a preexisting SCSSV.

## Claims

### Claim 1

A method for providing well safety control in a remedial electronic submersible pump (ESP) application comprising:
making up an electric submersible pump (ESP) on a conduit with including a primary well control capability;
running the ESP, conduit and primary well control capability through a preexisting Surface Controlled Subsurface Safety Valve) SCSSV, thereby impeding normal operation of the SCSSV.

### Claim 2 (depends on 1)

The method as claimed in claim 1 further comprising activating the primary well control capability.

### Claim 3 (depends on 2)

The method as claimed in claim 2 wherein activating the primary well control capability includes setting a packer in communication with a surface controlled subsurface safety valve (SCSSV) downhole of the ESP.

### Claim 4 (depends on 1)

The method as claimed in claim 1 further comprising pumping production fluid with the ESP through an annular space between a pre-existing production tubing string and the conduit.

### Claim 5 (depends on 1)

The method as claimed in claim 1 wherein the making up further includes positioning a piggyback sleeve to interact with the pre-existing SCSSV in the well.

### Claim 6 (depends on 1)

The method as claimed in claim 1 wherein the making up further includes disposing a chemical injection sub downhole of the ESP.

### Claim 7 (depends on 1)

The method as claimed in claim 1 wherein the making up further includes disposing a wet connect between the ESP and the primary well control capability.

### Claim 8 (depends on 7)

The method as claimed in claim 7 wherein the wet connect is positioned downhole of the ESP.

### Claim 9 (depends on 7)

The method as claimed in claim 7 wherein the wet connect is capable of disconnect and reconnect.

### Claim 10 (depends on 7)

The method as claimed in claim 7 further comprising:
disconnecting the wet connect, blowing down the well and pulling the ESP to surface.

### Claim 11 (depends on 10)

The method as claimed in claim 10 further comprising running an ESP into the well and connecting to the wet connect.

### Claim 12 (depends on 1)

The method as claimed in claim 1 wherein the conduit is a length of coiled tubing having a conductor therein.

### Claim 13 (depends on 1)

The method as claimed in claim 1 wherein the conduit is a length of power cable having a tensile strengthening member associated therewith.
