ABSTRACT:
Methods for determining formation characteristics comprising establishing baseline casing conditions for a string of casing disposed within a wellbore in a formation and measuring updated casing conditions for the string of casing at a first time interval from the establishing of the baseline casing conditions. The baseline casing conditions are compared to the updated casing conditions to determine changes in the string of casing over the first time interval. These changes in the string of casing are then used to determine formation characteristics.
