Program Professional Framework
Foundation (PL) Production Logging
Program Overview
Production logging shows where fluids enter or leave a well, making it essential for diagnosing water and gas breakthrough, crossflow, leaks and underperforming zones. This foundation course introduces production logging tools and interpretation: spinner flowmeters, temperature and pressure sensors, fluid density and holdup measurements, flow regimes in vertical and deviated wells, job planning and quality control, and single-phase and basic multiphase interpretation. Participants practise reading log passes and calibrating spinners to build zonal flow profiles, using examples from producers and water injectors in Gulf fields.

Training Methodology
Applied Project & Assessment
Applied Project
Participants interpret a provided production log from a Gulf oil producer or water injector, calibrate the spinner, build the zonal flow profile, identify the main problem and recommend a remedial or surveillance action in a short report.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
