Abstract

The invention is a method for automated management of hydrocarbon gathering systems. Measurement data is automatically collected from automated measurement and control devices that are located in a hydrocarbon production system The data that is collected is compared with data stored in a database. The comparison of data is used to automatically schedule tests of the plurality of automated measurement and control devices. The invention also automatically collects well test data, system balance data, and hydrocarbon composition data and uses the collected data to manage the hydrocarbon production and delivery process. The invention also automatically generates periodic grid reports concerning the status of the gathering system.

Claims

1. A method for automated management of hydrocarbon gathering, the method comprising:

collecting data from a plurality of automated measurement and control devices positioned in a hydrocarbon gathering system;

comparing the collected data with data stored in a database; and

using the data comparison to automatically schedule a test of at least one of the plurality of automated measurement and control devices.

2. The method of claim 1, wherein the data stored in the database is automatically updated with the collected data.

3. The method of claim 1, wherein the stored data comprises contractual provisions contained in contracts between a hydrocarbon gathering company and another entity.

4. The method of claim 3, wherein the contractual provisions comprise a testing frequency for the automated measurement and control devices.

5. The method of claim 1, wherein the collected data comprises test scheduling data defined by a hydrocarbon gathering company.

6. The method of claim 1, wherein the plurality of measurement and control devices comprises electronic flow meters.

7. The method of claim 1, wherein the plurality of automated measurement and control devices comprises programmable logic controllers.

8. The method of claim 1, wherein the plurality of automated measurement and control devices comprises remote terminal unit.

9. The method of claim 1, wherein the plurality of automated measurement and control devices comprises automated gas composition analysis devices.

10. The method of claim 1, wherein using the data comparison further comprises:

notifying a field technician of a required test for at least one of the plurality of automated measurement and control devices; and

automatically notifying a witness of the test after the field technician has selected a test date.

11. The method of claim 1, wherein the collected data and data stored in the database are used to model pipeline hydraulics.

12. The method of claim 1, further comprising:

using the collected data and data stored in the database to automatically generate a report for a selected unit of a hydrocarbon gathering system.

13. The method of claim 1, wherein the collected data and data stored in the database are used to evaluate reservoir production.

14. A method for automated management of hydrocarbon gathering, the method comprising:

collecting data from a plurality of automated measurement and control devices positioned in a hydrocarbon gathering system;

comparing the collected data with data stored in a database;

using the data comparison to automatically schedule a test of at least one of the plurality of automated measurement and control devices;

analyzing the collected data to determine a volume of a flow of hydrocarbons through at least one of the plurality of automated measurement and control devices;

comparing the volume of the hydrocarbon flow to contractual provisions stored in the database; and

automatically scheduling meter tests according to the stored contractual provisions.

15. The method of claim 14, further comprising:

automatically updating the database after testing of at least one of the plurality of automated measurement and control devices.

16. The method of claim 14, wherein selected field personnel are automatically notified of the automatically scheduled tests.

17. The method of claim 16, wherein the automatic notification is transmitted electronically.

18. The method of claim 14, wherein a witness is automatically notified of the automatically scheduled tests.

19. The method of claim 18, wherein the automatic notification is transmitted electronically.

20. The method of claim 14, further comprising:

testing at least one of the plurality of automated measurement and control devices;

automatically comparing test data with master testing data stored in the database; and

generating an alarm if a variance between the new testing data and the master testing data exceeds a selected threshold.

21. The method of claim 14, further comprising:

automatically measuring electrical current flow in at least one cathodic protection system positioned in the hydrocarbon gathering system; and

generating an alarm if the automatically measured electrical current flow exceeds a selected threshold.

22. The method of claim 14, wherein a computer system connected to the database automatically generates an alarm when a selected event is detected.

23. The method of claim 22, wherein the selected event comprises detection of non-conforming test data collected from at least one of the plurality of automated measurement and control devices.

24. The method of claim 22, wherein the selected event comprises detection of a failure of at least one of the plurality of automated measurement and control devices.

25. The method of claim 22, wherein the selected event comprises detection of a system imbalance beyond a selected threshold.

26. The method of claim 22, wherein the selected event comprises detection of a change in natural gas composition beyond a selected threshold.
