Conventional Production Logging: Temperature and Single-Element Spinners Fundamentals
e-Learning
About the eLearning Course
The goal of production logging is to obtain an accurate interpretation of downhole tool measurements of temperature, pressure, fluid holdups, and fluid velocities to determine flow rates of each phase. Achieving this goal requires understanding the measurements made by various production logging tools and how these tools make those measurements.
This skill module focuses on interpretation of single-phase flow. It covers temperature logs and single-element spinner-type flow meters and how to use them to determine flow rates for single-phase flow.
