Abstract
A method for using the depth derivative of distributed temperature sensing data to identify fluid levels, gas production intervals, water production intervals, and other fluid flow activities inside or near the well-bore during the production process. The method may include providing a fiber optic based distributed temperature sensing measurement system through a production region. Temperatures through the production region are gathered as a function of the depth in the subsurface well and as a function of the elapsed time. The gathered data is utilized to calculate the depth derivative of the temperature changes as a function of depth in the subsurface well and of the elapsed time. The depth derivative data for analysis of the fluid levels are displayed by operators to identify fluid levels, gas production intervals, water production intervals, and other fluid flow activities inside or near the wellbore during the production process.
