Abstract
A method for using the time derivative of distributed temperature sensing (DTS) data obtained during hydraulic fracturing to identify fluid activities not as evident in conventional DTS date inside or near the wellbore during the hydraulic fracturing process comprises providing a fiber optic based distributed temperature sensing measurement system through a production region; gathering the temperatures through the production region as a function of the depth in the subsurface well and as a function of the elapsed time; calculating from the gathered data the time derivative of the temperature changes as a function of depth in the subsurface well and of the elapsed time; and displaying the time derivative data for analysis of the fluid activities inside or near the wellbore during the hydraulic fracturing process to identify fluid activities inside or near the wellbore.
