Abstract
Methods for generating geometric databases of coiled tubing inspection data and using the data in job design, real time monitoring and automated feedback control of operations are described. One method includes creating a grid of spatial positions on a length of coiled tubing as it traverses through an inspection apparatus having a plurality of sensors for detecting defects in the coiled tubing. Real time data may be compared to historical or nominal data for the coiled tubing. Another method includes monitoring, in real time or near real time, the status of tubing dimension (thickness, diameter, ovality, shape) during a coiled tubing operation, such as acidizing, fracturing, high pressure operations, drilling, and wellbore cleanouts. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.
