Abstract: An information integration environment identifies the current drilling sites, and drilling equipment and processes at those current drilling sites. Based upon that identification, and upon data received from the drilling sites, servers access and configure software agents that are sent to a host client system at the drilling site; these software agents operate at the host client system to acquire data from sensors at the drilling site, to transmit that data to the information integration environment, and to derive the drilling state and drilling recommendations for the driller at the drilling site. These software agents include one or more rules, heuristics, or calibrations derived by the inference engine, and called by the information integration environment. In addition, the software agents sent from the information integration environment to the host client system operate to display values, trends, and reliability estimates for various drilling parameters, whether measured or calculated.

Abstract: A method, apparatus, and program storage device for integrating and implementing rule-based, heuristic, wellbore key performance rate of penetration indicators advising drilling operations personnel based on the situational awareness of trended earth properties and real time wellbore sensor data, is disclosed.
