Data fusion enhanced multi-modality wellbore integrity inspection system

A downhole inspection system, comprising:

• a first imaging device operable to generate first imaging data indicative of wellbore eccentricity anomalies, the first imaging device comprising:
• a first source operable to emit energy of a first modality based on a first physics-based mechanism;
• and
• a first detector operable to detect returning energy induced by the emitted energy of the first modality;
• a second imaging device operable to generate second imaging data, the second imaging device comprising:
• a second source operable to emit energy of a second modality based on a second physics-based mechanism different from the first physics-based mechanism;
• and
• a second detector operable to detect returning energy induced by the emitted energy of the second modality;
• and
• a processor configured to:
• receive the first imaging data and the second imaging data;
• reshape the first imaging data and the second imaging data to a common size;
• scale the first imaging data and the second imaging data to comparable intensity levels;
• and
• combine the eccentricity anomalies from the first imaging data with the second imaging data into an enhanced data stream.

A method of inspecting a wellbore, comprising:

• positioning a first imaging device in a wellbore having a casing comprising one or more layers;
• emitting energy of a first non-optical modality towards the wellbore;
• detecting first returning energy from the wellbore;
• generating first imaging data for detecting wellbore eccentricity anomalies-based at least in part on the detected first returning energy;
• positioning a second imaging device in the wellbore;
• generating energy of a second modality towards the wellbore;
• detecting second returning energy from the wellbore;
• generating second imaging data of the wellbore based at least in part on the detected second returning energy;
• reshaping the first imaging data and the second imaging data to a common size;
• scaling the first imaging data and the second imaging data to comparable intensity levels;
• and
• correlating the wellbore eccentricity anomalies from the first imaging data and the second imaging data to provide enhanced data for detecting wellbore anomalies.
