Why well monitoring instruments fail
This overview is intended to provide the reader with insight into basic reliability issues often confronted when designing long-term geothermal well monitoring equipment. No single system is looked at. General examples of the long-term reliability of other industries are presented. Examples of reliability issues involving electronic components and sensors along with fiber optic sensors and cables are given. This paper will aid in building systems where a long operating life is required. However, as no introductory paper can cover all reliability issues, basic assembly practices and testing concepts are presented.
