Challenge: Explain unexpected gas flow from three zones—two lower than expected and one much higher—in a hot, complex, naturally fractured carbonate reservoir.
Solution: Compare near-wellbore and far-field reservoir fractures by using 3D far-field sonic service to integrate results from the FMI fullbore formation microimager and Sonic Scanner acoustic scanning platform.
Results: Determined that the thin, high-flowing zone had excellent continuity between near- and far-field natural fractures, whereas the two low-producing zones had poor fracture connectivity.
