Patent ID: 8087461

Claim:
A production logging apparatus comprising: a coupling module providing a mechanical support for the production logging apparatus below a pumping arrangement (PA) disposed in a wellbore (WB), and allowing flow to enter the pumping arrangement (PA), the coupling module is separate from the pumping arrangement (PA) and couples the production logging apparatus to the pumping arrangement (PA), an electronic module comprising a winch controller, a powering module and a telemetry module, a micro-winch automated by the electronic module, a docking station comprising a latching mechanism for ensuring positive engagement of a micro-production logging tool with the production logging apparatus during docking, and the micro-production logging tool comprising at least one sensor and coupled to the micro-winch by a cable for regular production logging runs to measure the evolution of well characteristics, wherein the docking station is positioned entirely below the micro-winch when the production logging apparatus is disposed in the wellbore (WB).
