Treatment based on fiber cable sensor data
A method can include, during a treatment process, receiving vibration data acquired over a length of a fiber cable sensor disposed in a well that includes perforations; filtering the vibration data as to traveling waves to generate filtered data; analyzing the filtered data to generate fluid flow information; and adjusting the treatment process based at least in part on the fluid flow information.
1. A method comprising:
during a treatment process, receiving vibration data acquired over a length of a fiber cable sensor disposed in a well that comprises perforations;
filtering the vibration data as to traveling waves to generate filtered data;
analyzing the filtered data to generate fluid flow information; and
adjusting the treatment process based at least in part on the fluid flow information.
2. The method of claim 1 wherein the treatment process comprises pumping fluid into the well.
