Production Logging techniques and Interpretation of resulted figure: A case study of a gas field Iran

Traditionally, logging tools have been used to characterize formation and wellbore prior to the completion. However, studying and characterizing the reservoir during production can play a vital role in improving reservoir performance and production optimization. Production logging techniques are developed to assist with allocation of production to different zones as well as and diagnosing the production problems such as leaks or cross flow. This paper provides a review of such technology and tools used to conduct the production logging aiming at providing readers with a comprehensive understanding of production logging tools and sensors. In addition, in order to provide a better understanding of interpretation techniques and applications analysis of different cases of production logs is provided. Specifically, production log data from a gas field in Iran has been reviewed, analyzed and interpreted. The result of the study shows the importance of proper analysis and interpretation of such logs.
