ABSTRACT:
A mud logging system for receiving and displaying conditions measured during the drilling of a well includes a plurality of units for receiving and processing signals from sensors responsive to the values of the conditions. A/D convertors in each of said units produce digital representations of signals received from the sensors and the digital representations are utilized with visual display means in the units for digitally displaying values of the conditions. A slave computer of the digital type is interfaced with the A/D converters and a file disk. Under control of said slave computer the digital representatives are transferred to the file disk, and a recorder also under control of the slave computer displays selected ones of the conditions. The system also includes a master computer of the digital type connected to access data on the file disk, to utilize the accessed data to provide for analysis of drilling conditions.
