Data preprocessing system module used to improve predictive engine accuracy

A system for guiding well site operations, the system comprising:

• a plurality of sensors used to monitor well site operations equipment;
• at least one controller communicable coupled to the plurality of sensors and the well site operations equipment;
• an analysis module configured by a processor to:
• identify a well site operation by examining at least one well site operation variable;
• determine at least one semantic category and a standard operating procedure associated with the at least one semantic category using the well site operation and a-priori information;
• search a library of historical information using the at least one semantic category, the historical information comprising classified procedures and recommendations of historic well site operations;
• and
• a pattern recognition module configured by the processor to identify at least one pattern using a statistics based algorithm, the statistics based algorithm using the standard operating procedure, the at least one semantic category, the classified procedures and recommendations, the at least one pattern indicating a deviation in the standard operating procedure;
• a predictive engine configured by a processor to:
• generate predictive results used for guiding well site operations based on the at least one pattern.

• searching a library of historical information using the at least one semantic category, the historical information comprising classified procedures and recommendations of historic well site operations;
• and
• identifying at least one pattern using a statistics based algorithm, the statistics based algorithm using the standard operating procedure, the at least one semantic category, the classified procedures and recommendations, the at least one pattern indicating a deviation in the standard operating procedure.
