A method and apparatus for remote signal entry of control or data information from an equipment operator into an MWD system is presented. In accordance with an important feature of the present invention, the magnetometer, which is typically present in commercial MWD systems, is used as a communications channel for remote (e.g. wireless) transfer of data and/or control commands into the MWD tool. The present invention functions by replacing the direct electrical RS232 coupling with a wireless magnetic link. The invention uses the RS232 output of the operator's computer to drive its power amplifier which in turn drives the field coils in a transmitter. The axis of the field coils must be aligned with one of the sensitive axes of the magnetometer which, as mentioned, is a pre-exisitng part of the directional measurement system of the MWD apparatus. Thus, the present invention overcomes the necessity in the prior art for a direct RS232 link up between the surface computer and the computer on the MWD tool. |

DETAILED DESCRIPTION The above discussed and other drawbacks and deficiencies of the prior art are overcome or alleviated by the method and apparatus for remote signal entry of control or data information from an equipment operator into the MWD system.
In accordance with an important feature of the present invention, the magnetometer, which is typically present in commercial MWD systems, is used as a communications channel for remote (e.
g.
wireless) transfer of data and/or control commands into the MWD tool.
The present invention functions by replacing the direct electrical RS232 coupling with a wireless magnetic link.
The invention uses the RS232 output of the operator's computer to drive its power amplifier which in turn drives field coils in a transmitter.
The axis of the field coils must be aligned with one of the sensitive axes of the magnetometer which, as mentioned, is a pre-existing part of the directional measurement system of the MWD apparatus.
Thus, the present invention overcomes the necessity in the prior art for a direct RS232 link up between the surface computer and the computer on the MWD tool.
The above-discussed and features and advantages of the present invention will be appreciated and understood by those skilled in the art from the following detailed description and drawings.
