Positioning downhole-type tools

1. A method comprising:

interchangeably receiving a downhole tool of a plurality of interchangeable downhole tools by a pump-down adapter;

positioning the downhole tool, by the pump-down adapter, within a wellbore tubular;

releasing the downhole tool by the pump-down adapter;

receiving the downhole tool by the pump-down adapter; and

removing the downhole tool from a wellbore;

wherein removing the downhole tool comprises pumping fluid into an annulus and up the wellbore tubular, the pumped fluid increasing a pressure in a second portion of the wellbore tubular.

2. The method of claim 1 , further comprising seating the downhole tool within the wellbore tubular.

3. The method of claim 2 , wherein the downhole tool is seated prior to releasing the downhole tool by the pump-down adapter.

4. The method of claim 2 , wherein seating the downhole tool comprises extending a packer or hanger from a radial surface of the downhole tool by a battery powered extension system within the downhole tool.

5. The method of claim 1 , further comprising:

sealing, by one or more fins extending radially from an outer surface of the pump-down adapter, a first portion of the tubular uphole of the one or more fins, and the second portion of the tubular downhole of the one or more fins.

6. The method of claim 5 , wherein positioning the downhole tool comprises:

pumping fluid into the first portion of the tubular, the pumped fluid increasing a pressure in the first portion of the tubular, the increased pressure in the first portion of the tubular moves the pump-down adapter.

7. The method of claim 1 , wherein releasing the downhole tool comprises:

over pulling the pump-down adapter by a wireline; and

shearing a shear pin in response to the over pulling, the shear pin attaching the pump-down adapter and the downhole tool.

8. The method of claim 1 further comprising:

removing the pump-down adapter from the wellbore;

receiving a second downhole tool of the plurality of interchangeable downhole tools by the pump-down adapter; and

positioning the second downhole tool, by the pump-down adapter, within a wellbore tubular.

9. A method comprising:

attaching an interchangeable downhole tool of a plurality of interchangeable downhole tools to a pump-down adapter;

sealing, by one or more fins extending radially from an outer surface of the pump-down adapter, a first portion of the tubular uphole of the one or more fins, and a second portion of the tubular downhole of the one or more fins;

positioning the downhole tool and the pump-down adapter within a wellbore tubular;

separating the downhole tool from the pump-down adapter;

attaching the downhole tool to the pump-down adapter; and

removing the downhole tool and the pump-down adapter from a wellbore;

wherein removing the downhole tool comprises pumping fluid into an annulus and up the wellbore tubular, the pumped fluid increasing a pressure in the second portion of the tubular.

10. The method of claim 9 , wherein positioning the downhole tool and the pump-down adapter comprises:

pumping fluid into the first portion of the tubular, the pumped fluid increasing the pressure in the first portion of the tubular.

11. The method of claim 9 , wherein the downhole tool further comprises a fishing neck, and the pump-down adapter comprises a fishing tool configured to receive the fishing neck, wherein attaching the downhole tool to the pump-down adapter comprises securing the fishing tool to the fishing neck.

12. The method of claim 9 , wherein the downhole tool is a tubular puncher, the method further comprising forming a hole in a tubular wall by the tubular puncher.
