Abstract
An apparatus for providing a downhole measurement-while-drilling (MWD) tool with diagnostic capability by including one or more printed circuit boards to the tool with firmware processors that internally record significant system diagnostic events that can be time correlated with known tool operational problems. The concept includes firmware protocol to enable transfer all of the recorded data to an external software analysis program after the MWD tool is removed from a drilling run.
Claims26
A downhole measurement-while-drilling (MWD) tool with diagnostic capability comprising:
- directional sensors;
- electronics processing capability;
- a mud pulse telemetry assembly;
- a power source;
- and
- one or more printed circuit boards with firmware processors configured to internally record downhole system diagnostic events related to the one or more printed circuit boards, wherein the diagnostic events can be time correlated with known tool operational problems and are indicative of reliability of the one or more printed circuit boards,
- wherein said downhole measurement-while-drilling tool is configured to record and transmit measured MWD recorded events to a surface recording and display system.
An apparatus with diagnostic capability comprising a downhole measurement-while-drilling tool, wherein said tool records and transmits measured MWD recorded events to a display system;
- and wherein said tool comprises firmware processors that internally record downhole system diagnostic events related to the one or more printed circuit boards that can be time correlated with known tool operational problems and are indicative of reliability of the one or more printed circuit boards.
An MWD apparatus, the apparatus comprising:
- an MWD tool configured to be disposed in a borehole comprising:
- at least one printed circuit board disposed in the MWD tool;
- at least one firmware processor in communication with the at least one printed circuit board and configured to record and transmit at least one downhole system diagnostic event, wherein the at least one downhole system diagnostic event is indicative of reliability of the at least one printed circuit board.
