Abstract

A system includes a database that is adapted to store substantially continuously measured or calculated drilling parameters. At least one computer can access the database to display simultaneous user configurable graphical representations of selected drilling parameters. A user can observe multiple parameters graphically in real time.

Claims

1. A method of monitoring drilling parameters in real time, which comprises the computer implemented steps of:

displaying a list of drilling parameters;

in response to user selection of a set of drilling parameters from said list of drilling parameters, simultaneously displaying a graphical representation of each parameter of said set of drilling parameters.

2. The method as claimed in claim 1, including the computer implemented steps of:

prompting said user to enable operating limit alarms for at least some of said drilling parameters of said list; and

,

in response to enablement of said operating limit alarms, monitoring said at least some of said drilling parameters for operating limit alarm conditions.

3. The method as claimed in claim 2, including the computer implemented step of:

in response to detection of an operating limit alarm condition, producing an alarm.

4. The method as claimed in claim 2, including the computer implemented step of:

prompting said user to set operating limits for said at least some of said drilling parameters.

5. The method as claimed in claim 1, including the computer implemented steps of:

prompting said user to enable drilling event alarms; and

,

in response to enablement of said drilling event alarms, monitoring at least some of said drilling parameters for an occurrence of a drilling event signature.

6. The method as claimed in claim 5, including the computer implemented step of:

in response to detection of a drilling event signature, producing an alarm.

7. The method as claimed in claim 1, including the computer implemented steps of:

prompting said user to configure a display screen for displaying said graphical representation of each parameter of said set of drilling parameters; and

,

displaying said graphical representation of each parameter of said set of drilling parameters in accordance with configuration by said user.

8. The method as claimed in claim 7, wherein said step of prompting said user to configure said display screen includes the computer implemented steps of:

prompting said user to define an order of display of said selected drilling parameters.

9. The method as claimed in claim 7, wherein said step of prompting said user to configure said display screen includes the computer implemented steps of:

prompting said user to define a track width for each of said selected drilling parameters.

10. The method as claimed in claim 7, wherein said step of prompting said user to configure said display screen includes the computer implemented steps of:

prompting said user to specify an independent variable for the display of said selected drilling parameters.

11. The method as claimed in claim 10, wherein said independent variable is time.

12. The method as claimed in claim 10, wherein said independent variable is depth.

13. The method as claimed in claim 1, including the computer implemented steps:

prompting said user to save a display screen for displaying said graphical representation of each parameter of said set of drilling parameters; and

,

saving said display screen for displaying said graphical representation of each parameter of said set of drilling parameters.

14. The method as claimed in claim 13, including the computer implemented steps of:

displaying a list of display screens previously saved by said user; and

,

in response to selection of a previously saved screen, displaying said selected screen.

15. A method of monitoring drilling parameters in real time, which comprises the computer implemented step of:

prompting a user to select a display screen from a list including a pre-developed screen choice, a custom screen choice, and a standard screen choice, wherein each of said screens is adapted to display simultaneous real time graphical representations of a set of drilling parameters.

16. The method as claimed in claim 15, including the computer implemented steps of:

prompting said user to enable operating limit alarms for a second set of drilling parameters; and

,

in response to enablement of said operating limit alarms, monitoring said second set of drilling parameters for operating limit alarm conditions.

17. The method as claimed in claim 16, including the computer implemented step of:

in response to detection of an operating limit alarm condition, producing an alarm.

18. The method as claimed in claim 16, including the computer implemented step of:

prompting said user to set operating limits for said second set of drilling parameters.

19. The method as claimed in claim 15, including the computer implemented steps of:

prompting said user to enable drilling event alarms; and

,

in response to enablement of said drilling event alarms, monitoring at least some of said drilling parameters for an occurrence of a drilling event signature.

20. The method as claimed in claim 19, including the computer implemented step of:

in response to detection of a drilling event signature, producing an alarm.

21. The method as claimed in claim 15, including the computer implemented steps of:

in response to selection of said custom screen choice, displaying a list of drilling parameters; and

,

prompting said user to select a set of drilling parameters from said list of drilling parameters.

22. The method as claimed in claim 21, including the computer implemented steps of:

in response to selection by said user of a set of drilling parameters, prompting said user to configure a display screen for displaying said graphical representation of each parameter of the selected set of drilling parameters; and

,

displaying said graphical representation of each parameter of said selected set of drilling parameters in accordance with configuration by said user.

23. The method as claimed in claim 21, including the computer implemented steps:

in response to selection by said user of a set of drilling parameters, prompting said user to save a display screen for displaying said graphical representation of each parameter of said selected set of drilling parameters; and

,

saving said display screen for displaying said graphical representation of each parameter of said selected set of drilling parameters as a pre-developed screen.

24. The method as claimed in claim 15, including the computer implemented step of:

in response to user selection of said predeveloped screen choice, displaying a list of predeveloped screens.

25. The method as claimed in claim 15, including the computer implemented step of:

in response to user selection of said standard screen choice, displaying a list of standard screens.
