Diagnostic Methods: Integrity Tests

Wells are designed and constructed to withstand some pressure on the annuli during operation. However, this pressure becomes an issue when there is an indication of a well integrity failure or if the maximum allowable wellhead operating pressure has been exceeded. In this case, the correct response may vary based on the pressure’s source and the local regulations that are in effect. As a result, it’s crucial to regularly monitor annular pressure and identify the pressure’s source. This chapter introduces the main diagnostic methods to detect failures in wellbore integrity. Most of these techniques rely on data from operators’ routine production tests, including fluid sample analysis, fluid levels, or wellhead/casing pressure testing. Identifying the source can allow for proper remediation and design improvements for future operations.
