Production Logging

154 result(s) found.

production logging  Production logging tools are run in completed wells to ascertain the nature and behavior of fluids in or around the borehole during production or injection. These logs are used to analyze dynamic well performance and the productivity or injectivity of different zones, to diagnose problem wells, or to monitor results of a stimulation or completion. This discipline deals with a variety of techniques used to measure well performance, with terms ranging from annular flow to basket flowmeter, from holdup to water-cut meter. All terms have been defined by experts in the production logging domain, and many definitions include high-quality illustrations or photographs.
