## Abstract

A method for performing simultaneous operations at a wellsite comprising two or more adjacent wellheads, each respectively connected to a well, may include the following steps: providing a fluid supply via upstream equipment to an intermediate supply point; fluidly connecting the intermediate supply point to a single wellhead, the fluidly connecting comprising connecting a first end of a flexible pipe to the intermediate supply point and a second end of the flexible pipe to a first wellhead; performing a wellbore operation on a first well using the fluid supply from the upstream equipment supplied to the first wellhead; disconnecting the second end of the flexible pipe from the first wellhead; and connecting the second end of the flexible pipe to a second wellhead.

## Claims

### Claim 1

A system for performing operations on adjacent wells, comprising:
two or more pump trucks;
a pump manifold consolidating a flow of fluid from the two or more pump trucks;
two or more wellheads; and
one or both of:
a flexible pipe fluidly connecting the pump manifold to a single one of the two or more wellheads;
a flexible pipe fluidly connecting, respectively, a high pressure outlet of each of the two or more pump trucks to the pump manifold,
wherein the goat head or Christmas tree comprises a fluid connection terminating in a downward facing wellhead connection point configured to connect to an end of the flexible pipe.

### Claim 2 (depends on 1)

The system of claim 1, wherein the pump manifold is not fluidly connected to a second of the two or more wellheads.

### Claim 3 (depends on 1)

The system of claim 1, wherein an isolation valve is disposed between an outlet of the pump manifold and the flexible pipe.

### Claim 4 (depends on 1)

The system of claim 1, wherein an isolation valve is disposed between an end of the flexible pipe and the wellhead.

### Claim 5 (depends on 1)

The system of claim 1, further comprising a cradle proximate a connection point of each of the two or more wellheads, wherein the cradles are configured to guide an end of the flexible pipe into alignment with the connection point of a respective wellhead.

### Claim 6 (depends on 1)

The system of claim 1, wherein the flexible pipes connecting the high pressure outlet of the pump trucks to the pump manifold each comprise a section disposed in an S-shape.

### Claim 7 (depends on 1)

The system of claim 1, wherein the flexible pipe connecting the pump manifold to the single one of the two or more wellheads comprises a section disposed in an S-shape.

### Claim 8 (depends on 1)

The system of claim 1, further comprising a wireline operation system connected to a second of the two or more wellheads.

### Claim 9 (depends on 1)

The system of claim 1, further comprising a goat head or Christmas tree disposed on the wellhead for facilitating a fluid connection between an end of the flexible pipe and the wellhead.

### Claim 10 (depends on 1)

The system of claim 1, wherein the downward facing connection point is at an angle from 0 to 50 degrees from vertical.

### Claim 11 (depends on 1)

The system of claim 1, wherein the downward facing connection point is at an elevation of less than 7 feet from ground level.

### Claim 12 (depends on 1)

The system of claim 1, wherein the flexible connection line comprises a section disposed in an S-shape.
