System and process for determining well integrity for plug and abandonment

Abstract

The present invention provides a process for determining a hydrocarbon well integrity prior to plugging the well for abandonment, wherein the well comprises a settable medium in a casing, the process comprising the steps of: providing a first tool adjacent to the casing for acquiring a set of data related to settable medium for determining the condition of the settable medium; providing a second tool for acquiring spectral noise data within the well for detecting any unwanted interference or obstruction within the well; providing an analyzing system for receiving data from first and second tools, analyzing said data and generating a well integrity report for use in determining whether said well is in an acceptable condition for plugging and subsequently abandonment of well; wherein the acquired data from the first tool and second tool is analyzed simultaneously by the system prior to generating the well integrity report.
