Latest Patents

Bettinelli is credited with 1 patent: “Method to Perform Selection of Optical Gauge Length of Fibers Used in Hydrocarbon Recovery Operations, Carbon Capture and Sequestration, and Geothermal Applications.”

The invention describes a method for selecting an appropriate optical-fiber gauge length. It obtains data from optical fibers, processes the data using a fixed gauge length, and uses an autonomous computing arrangement to estimate apparent velocity and source bandwidth. The method then establishes a variable gauge length and reference profile, and processes the data again to produce a processed optical data set. These steps are intended to support fiber-optic sensing in wellbore environments across energy and geothermal applications.
