Patent attributes
An instrument, such as a wall-thickness, rod-wear, or pitting sensor, can monitor tubing as a field service crew extracts the tubing from an oil well or inserts the tubing into the well. A digital system can process data from the instrument to improve the data's fidelity, quality, or usefulness. Digital signal processing can comprise filtering or otherwise manipulating the data to provide refined data that a person or machine can readily interpret. For example, a graphical representation of the refined data can help an operator evaluate whether a segment of tubing is fit for continued service. Processing tubing data can comprise applying a flexible level of filtering, smoothing, or averaging to the data, wherein the level changes based on a criterion or according to a rule. The level can vary in response to a change in tubing speed, noise in the raw data, or some other parameter.
