Abstract

The present invention provides a system, apparatus and method for transmitting logging data from a primary location to a remote location in near real time. The logs can be viewed almost simultaneously at the primary and remote locations, as data is being acquired.

The present invention also provides for a system for viewing logs in near real time at a primary location and a remote location which includes a first means for reading while writing at the primary location, a second means for reading while writing at the remote location which is identical to the first means for reading while writing, a first file system at the primary location, the first file system having data written to it by the first means for reading while writing as numerical data or graphics data, a first rendering means for reading the graphics data from the first file system and rendering the graphics data so that it can be displayed, a first display means for displaying the rendered graphics data, a first file transfer utility means for transmitting the data from the primary location to the remote location over a communications system, a second file transfer utility means for receiving the data at the remote location, a second file system at the remote location, to which the second file transfer utility means writes the received data using the second means for reading while writing, a second rendering means for reading graphics data from the second file system and rendering the graphics data so that it can be displayed, a input interface means which directs signals from an user input to the second rendering means to adjust the display of the log, and a second display means for displaying the rendered graphics data at the remote location.

Claims

1. A system for viewing data in near real time at a remote location connected via communications channel, comprising:

a) a data acquisition module operable to collect data;

b) a file system connected to the data acquisition module and operable to store the data;

c) a file transfer mechanism connected to the file system and to the communications channel; and

d) a first read while write module connected to the data acquisition module and the file transfer mechanism, and operable to enable the file transfer mechanism to transfer data to the communications channel at the same time as the data is being written into the file system.

2. The system for viewing data in near real time at a remote location of claim 1, wherein the file transfer mechanism is incorporated into the data acquisition module.

3. The system for viewing data in near real time at a remote location of claim 1, further comprising:

e) a well logging tool connected to the data acquisition module via a wireline cable, and operable to measure geophysical properties in a bore hole.

4. The system for viewing data in near real time at a remote location of claim 3, further comprising a telemetry system connecting the well logging tool to the data acquisition module and wherein the telemetry system is operable to transmit data from the well logging tool to the data acquisition module.

5. The system for viewing data in near real time at a remote location of claim 3, further comprising:

a remote file transfer system connected to the communications link;

a remote file system connected to the remote file transfer system;

a second read while write module connected to the remote file system; and

rendering means at the second read while write module;

wherein the second read while write module retrieves data from the remote file system while data is being written to the remote file system and wherein the second read while write module transfers the data to the rendering means whereby the data is rendered while collected by the data acquisition system.

6. The system for viewing data in near real time at a remote location of claim 1, wherein the data is stored in the file system in a first format file.

7. The system for viewing data in near real time at remote location of claim 6, wherein the data is stored in the file system in a second format file.

8. The system for viewing data in near real time at remote location of claim 7, wherein the first format file is a log graphics file and the second format file is a log data file.

9. A method for operating a communications system having a primary location and a remote location connected via a communications channel for viewing data in near real time at the remote location, comprising:

a) collecting geophysical data;

b) writing the geophysical data to a file system;

c) while writing the geophysical data to a file system, reading the geophysical data; and

d) while writing the geophysical data to a file system, transmitting the geophysical data to a remote location.

10. The method for operating a communications system having a primary location and a remote location of claim 9, further comprising:

e) receiving the geophysical data at the remote location;

f) writing the geophysical data to a remote file system at the remote location; and

g) while writing the geophysical data to the remote file system, rendering the data.

11. The method for operating a communications system having a primary location and a remote location of claim 9, wherein the data is log data.

12. The method for operating a communications system having a primary location and a remote location of claim 9, wherein the data is log graphics.

13. The method for operating a communications system having a primary location and a remote location of claim 9, wherein the step b) of writing the geophysical data to a file system, comprises writing the geophysical data to a log graphics file and to a log data file.
