Lecture Presentation Fundamentals of Well Logging Caliper and Temperature Logging Carlos Torres-Verdín, Ph.D. Professor Department of Petroleum and Geosystems Engineering The University of Texas at Austin Objectives: 1. To understand the importance of borehole environmental variables, especially borehole rugosity and temperature, 2. To understand the principles of operation of caliper logging tools and temperature-recording devices, 3. To emphasize the sensitivity of pad and mandrel tools to variations of borehole caliper and temperature along the borehole, and 4. To introduce the types of logs used to perform quality control of well-logging measurements
