Description:
Regulations of the Environmental Protection Agency require that an injection well exhibit both internal and external mechanical integrity. The external mechanical integrity consideration is that there is no significant fluid movement into an underground source of drinking water through vertical channels adjacent to the injection well bore. Mechanical integrity problems both related and non related to injection can be investigated using the three logging tools: radioactive tracer, noise, and temperature. The operational principles of each tool are discussed, followed by the principles by which the tools detect flow and examples of the tool being used in such application. Finally, general operational guidelines are outlined to assist the reader in the application of each tool.
