Abstract:
Provided herein are systems, methods, and computer-readable medium for profiling steam injected into a formation. In one embodiment, the method includes receiving a dataset of temperature surveillance data, acoustic surveillance data, surface injection data, downhole pressure measurement device data, downhole temperature measurement device data, or any combination thereof. The method further include determining annular temperature profiles, tubing temperature profiles, behind liner temperature profiles, or any combination thereof from the dataset based on configuration of the fiber optic surveillance system in the well and design of the well. The method further includes using flow diagnostic results based on the dataset, the annular temperature profiles, the tubing temperature profiles, etc. to select which computational algorithm(s) can be used to determine a steam injection flow profile and associating each selected algorithm with a weight, executing each selected algorithm, and using results and the associated weight to determine the steam injection flow profile.
