A computer-implemented, machine learning-based method of converting an unstructured technical report into a structured technical report includes obtaining an unstructured technical report, tokenizing the unstructured technical report into an n-gram array, identifying and filtering non-interesting n-grams from the first n-gram array based on common language usage of the non-interesting n-grams and a determination that the non-interesting n-grams do not appear on a confirmed technical entity database, generating and displaying a technical entity candidate list from the filtered n-gram array, displaying, obtaining, from a pattern matching model and/or a graphical user interface, an indication that a technical entity candidate is a technical entity of interest, appending the technical entity of interest to the confirmed technical entity database, generating and displaying a structured technical report with the confirmed technical entities and corresponding technical entity value parameters, and iterating the process to refine the pattern matching model.

A method () and an assembly () for milling an obstruction disposed within a wellbore (W) includes a milling module () having a motor () rotating a milling bit (), a first electronics cartridge () for controlling the motor based upon a motor torque value, a tractor module () for engaging with the wellbore and providing a push force against the wellbore to urge the milling assembly in a direction of the milling bit, and a second electronics cartridge () for controlling a push force value of tractor module. The method involves rotating the milling bit () and engaging the tractor module with the wellbore (), and adjusting, iteratively, the operation () based on a calculated torque value and a calculated push force value to maintain the calculated values at around a target torque value and below a push force limit value ().
