Techlog Processing and Interpretation of Quanta Geo Images with Techlog Fundamentals

Participants are trained to use the Techlog wellbore software platform to perform processing and interpretation of photorealistic Quanta Geo formation images. A simplified physics lecture gives students a foundation of understanding the Quanta Geo physics of measurement. Starting from raw Quanta Geo data, students are taught to apply tool-specific signal processing methods in Techlog to remove borehole and mud effects and produce images that are most representative of the formation. Students then learn to use and optimize standard Techlog Wellbore Imaging (Wbi) methods to optimally process and visualize Quanta Geo images for interpretation. Emphasis is placed on the recognition of artifacts, and the corrective actions to take to eliminate them. Optimum adaptation of common Techlog Wbi interpretation workflows is then covered, considering eventual processing artifacts and considering the nature of Quanta Geo images being acquired in resistive oil-base mud.
