Abstract
Production logging apparatus and method are provided. The apparatus comprises a coupling module, an electronic module, a micro-winch, a docking station, and a micro-production logging tool. The coupling module provides mechanical support for the production logging apparatus below a pumping arrangement disposed in a wellbore, and allows flow to enter the pumping arrangement. The electronic module comprises a winch controller, a powering module and a telemetry module, and adapted to automate the micro-winch. The docking station comprises 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 comprises at least one sensor and is coupled to the micro-winch by a cable for regular production logging runs to measure the evolution of well characteristics.
