SYSTEM, METHOD, AND APPARATUS FOR VISUALIZING CHANGES IN CYLINDRICAL VOLUMES

摘要

A method includes interpreting first dimensional data such as a caliper log for a wellbore at a first time, and interpreting second dimensional data such as a caliper log for the wellbore at a second time. The method further includes determining a dimensional differential in response to the first dimensional data and the second dimensional data. The dimensional differential includes a volume difference between cross-sectional profiles from the first dimensional data and the second dimensional data. The cross- sectional profiles for comparison may be at a specified axial location or range of axial locations in the wellbore. The method includes graphically displaying the dimensional differential by marking the dimensional differential with a first marker index where the first dimensional data is inside the second dimensional data, and with a second marker index where the first dimensional data is outside the second dimensional data.
