Evaluating annular material in a wellbore using transient thermal response data

Evaluating annular material in a wellbore using transient thermal response data

A method for identifying zones in an annulus with poor cementing that may include deploying a fiber optic cable within the wellbore, creating a temperature gradient in the wellbore, and collecting temperature data over a period of time as the wellbore returns to a thermal equilibrium. The method may...

description A method for identifying zones in an annulus with poor cementing that may include deploying a fiber optic cable within the wellbore, creating a temperature gradient in the wellbore, and collecting temperature data over a period of time as the wellbore returns to a thermal equilibrium. The method may also include comparing the temperature data collected by the fiber optic cable at one or more locations to predicted temperature data over the period of time at the one or more locations to identify locations where the measured temperature data deviates from the predicted temperature data for identifying locations or zones of the annulus that have poor cementing.
