Methods and apparatus for retrieving a wireline using a release sub

A method, comprising:

• conveying a downhole tool into a wellbore, wherein the downhole tool includes:
• a release sub disposed between a first section of the downhole tool and a second section of the downhole tool,
• wherein the release sub includes:
• a first portion including:
• a threaded pin;
• an electric motor;
• a second portion including a threaded box, wherein the threaded pin is threaded into the threaded box to couple the first portion to the second portion,
• wherein the first section of the downhole tool includes a connector connected to a wireline extending from an opening of the wellbore to the downhole tool,
• wherein the second section of the downhole tool includes a fish neck;
• causing the electric motor to rotate the threaded pin relative to the threaded box to decouple the first portion from the second portion, wherein the first section of the downhole tool is at least partially detached from the second section of the downhole tool;
• pulling the wireline from the opening of the wellbore to retrieve the wireline and the first section of the downhole tool;
• and
• using the fish neck to fish the second section of the downhole tool from the wellbore.
