THE PROJECT AIMS TO DESIGN, DEVELOP, PROTOTYPE, AND VALIDATE A NOVEL AI-ENABLED, PHOTOACOUSTIC IMAGING (PAI) BASED WELL-LOGGING TOOL FOR COMPREHENSIVE EVALUATION OF THE INTEGRITY OF GEOTHERMAL WELLS AT HIGH TEMPERATURE AND HIGH PRESSURE WITHOUT ACTIVE COOLING. THE PROPOSED TECHNOLOGY IS A HIGH-FIDELITY COMPLETE INSPECTION TOOL THAT IS COMPATIBLE WITH CURRENT CONVEYANCE METHODS. THE NEW TOOL WILL PROVIDE THE FULL, CONTINUOUS 3D TOMOGRAPH OF WELLBORE (CASING, CEMENT, PART OF FORMATION) WITH DEFECTS IDENTIFIED, CLASSIFIED, AND DISPLAYED/OVERLAID.
