Abstract

A system for pump down operations includes a diversion valve unit that is adjustable between a pumping position and a diversion position and a controller coupled to the diversion valve unit. The system further includes a fluid reservoir, a downhole fluid path between the fluid reservoir and a tool downhole, a driving unit in the downhole fluid path for advancing the tool, and a diversion fluid path between a portion of the downhole fluid path downstream of the driving unit and the fluid reservoir or another fluid receptacle. The diversion valve is in the diversion fluid path and the controller automates the diversion valve position for the diversion valve unit based on a monitored wireline speed or a monitored wireline tension for a wireline unit.
