.... This segregation phenomenon, if not accounted for, results in erroneous cement interpretation answers with uncertainty, such as low-acoustic impedance stripe in the direction of heavier mud components. A new advanced ultrasonic technology and its embedded unique inversion processing known as R+, based on 3...

... from seismic interpretation are ultra-deep electromagnetic (EM) tools. Applying geophysical inversion processes to the ultra-deep resistivity data generates models that enhance the reservoir interpretation. Formation boundary identification and definition of thin layers in the vertical plane can...

... annulus contents observed from ultrasonic and sonic log data. The innovative use of the data interpretation with advanced workflows decreased uncertainties about the annulus contents and enabled following an informed C&P strategy. In all three cases, the casing sections were retrieved without...

.... In this paper, we present an innovative approach that combines DAS and DTS information together to provide an accurate inflow profile of a gas producing well. The results of inflow profiling using DFOS were compared with a conventional production log interpretation and presented in this paper. DFOS...

... This verification is done by both surface and downhole monitoring. Interpretation of test results may be challenged by multiple downhole factors and may leave the risk the WBE failure during the test and later after the well was abandoned. In the worst scenarios, the abandoned well will require...

The tool provided a real-time resistivity profile that could be interpreted up to 80 ft above and below the wellbore...
