Title: METHOD FOR INTERPRETATION OF DISTRIBUTED TEMPERATURE SENSORS DURING WELLBORE OPERATIONS
Abstract:
An embodiment for determining a flow distribution of a wellbore during a wellbore treatment comprises disposing an optical fiber into a wellbore, performing a wellbore treatment in the wellbore with the fiber optic in place by flowing a well treatment fluid from the surface and wellbore and into the formation, taking distributed temperature measurements at a time interval with the fiber optic cable during the wellbore treatment operation, and calculating a flow distribution of the wellbore while performing the wellbore treatment.
