Abstract
A wireline clean-out tool including a first opening and a second opening at or near a free-end portion. The first opening takes in debris from a wellbore, the second opening ejects fluid into the wellbore. A housing defines a first flow path from the first opening at the free-end portion to an opposite end portion of the housing and a second flow path from the opposite end portion to the second opening at the free-end portion. The flow paths couple with each other at the opposite end portion. A collection chamber is in the first flow path for collecting debris during operation. A progressive cavity pump with hollow rotors is placed inside the housing at a predefined distance from the free-end portion being configured for operating on the first flow path while the hollow rotor forms part of the second flow path.
