A computerized data monitoring system has been designed and built for use on oil well drilling rigs. The system is designed to perform the following: collect data for future analysis, do on-site data interpretation, compute drilling optimization values, and detect alarm conditions during the drilling process. Due to the difficult physical conditions of the oil field, limited operator training time, and tradition-bound attitudes, many problems have been encountered. Hardware changes have been made during the evolution of the system to minimize the physical problems of poor electrical power, dust, and vibration. Human engineering has been applied to reduce the man-machine interface problem. The system which consists of a minicomputer interfaced to mud logging sensor panels has been field tested in Texas, Oklahoma, Utah, and the North Sea. An analysis of the system has been made and the strengths and weaknesses noted.
