Production logging

Definition

Production logging is a process used in the oil and gas industry to collect data about the performance and behavior of a well after it has been completed. This involves measuring various parameters, such as flow rates, pressure, temperature, and fluid composition, to assess the well's productivity and reservoir characteristics. Understanding production logging is crucial for optimizing extraction processes and managing resources effectively.
