Abstract:
1. A method usable with a wellbore, comprising: stopping injection of fluid into a formation, the formation intersected by a wellbore having an uphole section uphole of the formation and a formation section within the formation; observing temperature at least partially along the uphole section of the wellbore and at least partially along the formation section of the wellbore, while injection of fluid is stopped; re-starting injection of fluid into the formation in response to observation of a temperature peak in the uphole section of the wellbore; observing, while re-starting injection of fluid is occurring, the movement of the peaked temperature fluid as it moves from the uphole section of the wellbore and across the formation section of the wellbore; and determining an inflow profile of the formation based on the movement of the peaked temperature fluid that is observed while re-starting injection of fluid is occurring.
