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.

Learning Outcomes

✓Explain the measurement principles of spinner, temperature, pressure, density and holdup sensors.
✓Plan a logging job, including well conditions, passes, stations and logging speeds.
✓Perform in-situ spinner calibration and calculate fluid velocities from multiple passes.
✓Build a single-phase flow profile for a producer or water injector.
✓Interpret basic two-phase flow using holdup and density data.
✓Identify common problems such as crossflow, casing leaks and water entry from log responses.

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.
