Abstract: Methods may include recording pressure and/or temperature data at two or more time points in a region adjacent an isolated zone in a wellbore created by one or more isolation devices; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data. Methods may also include injecting a fluid into an isolated zone in a wellbore created by one or more isolation devices; recording pressure and/or temperature data at two or more time points in a region adjacent the isolated zone; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data.
