Method and system for calibrating a downhole imaging tool

摘要

System and methods of generating calibrated downhole images of a subterranean formation (110) surrounding a wellbore (105). The method involves measuring open hole and cased hole measurements with a downhole tool (132); determining (698) open hole parameters (e.g., Z90) from the cased hole parameters, known parameters and the open hole measurements; and generating (699) downhole outputs from the determined open hole parameters.
