Method and system for simultaneous wireline milling and debris collection

A method of simultaneous milling and debris collection, the method comprising:

• providing a tool, the tool comprising:
• a motor;
• a gear train coupled to the motor, the gear train including a first rotational output and a second rotational output, the first rotational output and the second rotational output having different rotational speeds relative to each other;
• a fluid pump coupled to both the first rotational output and the second rotational output of the gear train, the fluid pump comprising:
• a pump housing coupled to the first rotational output of the gear train, and
• a pump input coupled to the second rotational output of the gear train;
• and
• a milling bailer coupled to the housing of the fluid pump and configured to rotate with the fluid pump housing, the milling bailer comprising:
• a bailer portion shaped to intake fluid proximate a distal end of the bailer portion and allow the fluid to flow through a filter and through the fluid pump;
• and
• a milling face proximate the distal end of the bailer portion, the milling face comprising at least one bit for milling and configured to perform a milling operation while the fluid is flowing through the bailer portion;
• lowering the tool down a well using a wireline;
• positioning the tool such that the milling face is in contact with a surface to be milled;
• and
• operating the motor such that the milling bailer rotates, causing the milling face to mill the surface while the fluid flows through the bailer portion to the fluid pump.
