Production Logging Principles


This course introduces fundamental concepts used for production logging in vertical and deviated wells. Quantifying multiphase flow will be illustrated by introducing the hold-up principle and its measurement tools. The course enables the participants to adjust data acquisition programs selecting the best set of sensors depending on fluids being produced, well deviation, completions type, and objective of the log. The course includes a review of advanced PL technology and its use.

Targeted Groups:

Reservoir and Production Engineers
