System And Method For Well-Logging
US Patent:
4350979, Sep 21, 1982
Filed:
Apr 13, 1979
Appl. No.:
6/030056
Inventors:
Valery D. Eberwein - Houston TX
Assignee:
Dresser Industries, Inc. - Dallas TX
International Classification:
G01V 140
US Classification:
340861
Abstract:
An improved system and method is provided for obtaining information related to subsurface earth formations. Well-logging data from an input terminal is processed and stored in a memory by a first processor. A second processor retrieves this data from the same memory, and further processes the data, which is then transferred to an output terminal device. The first processor obtains access to memory or the input terminal for delivering or retrieving data during pulses of a first pulse train generated by a clock. The second processor obtains access to the same memory or the output terminal for delivery or retrieval of data during pulses of a second pulse train generated by the clock. Performance of each processor's respective functions is synchronized by storage and retrieval of messages by both processors in the common memory.
