## Abstract

A system includes an overshot body, an engagement mechanism, a cutter body, a disk assembly, and a motor. The overshot body has an overshot conduit. The overshot conduit is configured to receive the external circumferential surface of the tubular body. The engagement mechanism is disposed within the overshot conduit, connected to the overshot body, and configured to engage with the external circumferential surface of the tubular body. The cutter body is connected to the overshot body and is configured to enter the tubular conduit. The disk assembly is rotatably connected to the cutter body. The motor is located within an orifice of the cutter body and is configured to rotate the disk assembly.

## Claims

### Claim 1

A system for interaction with a tubular body having an external circumferential surface and a tubular conduit, the system comprising:
an overshot body having an overshot conduit, wherein the overshot conduit is configured to receive the external circumferential surface of the tubular body;
an engagement mechanism disposed within the overshot conduit, connected to the overshot body, and configured to engage with the external circumferential surface of the tubular body;
a cutter body connected to the overshot body, wherein the cutter body is configured to enter the tubular conduit;
a disk assembly rotatably connected to the cutter body; and
an electric motor located within an orifice of the cutter body and configured to rotate the disk assembly,
wherein the electric motor is configured to receive a signal and power from a wireline connected to the overshot body, and
wherein the electric motor is electrically connected to the wireline through the cutter body.

### Claim 2 (depends on 1)

The system of claim 1, wherein the cutter body is connected to the overshot body using one or more extension pipes and a distance between the cutter body and the overshot body is determined by a number and a length of the one or more extension pipes.

### Claim 3 (depends on 1)

The system of claim 1, wherein the overshot body is connected to a drill string.

### Claim 4 (depends on 1)

The system of claim 1, wherein the engagement mechanism further comprises a grapple.

### Claim 5 (depends on 1)

The system of claim 1, wherein the engagement mechanism further comprises a set of slips.

### Claim 6

A method for pulling a tubular body having an external circumferential surface and a tubular conduit from a well, the method comprising:
providing a fishing tool comprising:
an overshot body having an overshot conduit,
an engagement mechanism disposed within the overshot conduit, connected to the overshot body,
a cutter body connected to the overshot body,
a disk assembly rotatably connected to the cutter body, and
an electric motor located within an orifice of the cutter body and configured to rotate the disk assembly;
running the fishing tool into the well;
lowering the cutter body and the disk assembly into the tubular conduit of the tubular body until the tubular body enters the overshot conduit;
cutting the tubular body using the disk assembly;
activating the engagement mechanism to engage with the external circumferential surface of the tubular body; and
pulling a severed portion of the tubular body from the well using the fishing tool,
electrically connecting the electric motor through the cutter body with a wireline connected to the overshot body, and
sending a signal and power using the wireline to the electric motor using the wireline.

### Claim 7 (depends on 6)

The method of claim 6, wherein providing the fishing tool further comprises connecting the cutter body to the overshot body using one or more extension pipes.

### Claim 8 (depends on 6)

The method of claim 6, wherein running the fishing tool into the well further comprises connecting the overshot body to a drill string.

### Claim 9 (depends on 6)

The method of claim 6, wherein the engagement mechanism further comprises a grapple.

### Claim 10 (depends on 6)

The method of claim 6, wherein the engagement mechanism further comprises a set of slips.
