Abstract

In one aspect, a method is provided for controlling fluid flow in a wellbore containing a plurality of production devices, wherein the method includes the steps of defining a first setting of each production device in the plurality of production devices, defining a change in a parameter relating to fluid flow in the wellbore and using a model to determine a second setting for at least one of the plurality of production devices based on the change in the parameter. The method also includes the step of generating a script corresponding to the second setting, wherein the script is configured to be implemented without modification, and storing the script in a suitable storage medium.

Claims

1. A method for controlling formation fluid flow into a production wellbore containing a plurality of production devices, comprising:

defining a first setting of each production device in the plurality of production devices, wherein the first setting of a selected production device determines a first flow rate of formation fluid flowing from a formation into a production tubular in the wellbore, the formation fluid comprising at least one of oil and gas;

displaying, at a user interface, a first chart showing a status indicator representing the plurality of production devices over a length of the production wellbore and indicating their status, the first chart further showing measurements of a parameter related to the first flow rate of formation fluid obtained at the plurality of production devices at a selected time;

displaying, at the user interface, a second chart showing the measurements of the parameter over time at a selected position;

graphically manipulating the measurements of the parameter in the first chart to indicate a desired flow rate at a selected depth;

using a model to determine a second setting for at least one of the plurality of production devices based on the desired flow rate at the selected depth;

generating a script corresponding to the second setting;

submitting the script to an operator for approval; and

implementing the script without modification upon approval of the operator.

2. The method of claim 1, wherein using the model to determine the second setting comprises determining a sequence of settings for the plurality of production devices.

3. The method of claim 1 further comprising transmitting the script to a controller for implementing the script.

4. The method of claim 1, wherein the production devices are selected from the group consisting of:

valves, chokes, and chemical treatment devices.

5. The method of claim 1 further comprising providing the script to the operator via one of:

a portable memory device; and

via a communication network.

6. The method of claim 1 further comprising providing the script to the operator via a communication network.

7. The method of claim 6, wherein providing the script includes providing options to:

run the script;

reject the script; and

delay use of the script.

8. A method for controlling wellbore devices in a wellbore for production of formation fluid, comprising:

measuring values of at least one production parameter at a plurality of production device over a length of the production wellbore, the production parameter relating to production of formation fluid comprising at least one of oil and gas from a formation into a production tubular at a selected depth;

displaying, at a user interface, a first chart showing a status indicator representing the plurality of production devices over a length of the production wellbore and indicating their status, the first chart further showing the measured values obtained at the plurality of production devices at a selected time;

displaying, at the user interface, a second chart showing the measured values over time at a selected position;

graphically manipulating the measurements in the first chart to indicate a desired value for the at least one production parameter at a selected location;

processing the desired value to determine a setting of at least one production device which provides the desired value when implemented, wherein the at least one production device comprises a production device that is controlled to regulate a flow of a formation fluid;

creating a script file corresponding to the setting;

submitting the script file to an operator for approval; and

implementing the script file without modification to change a setting of the at least one production device upon approval of the operator.

9. The method of claim 8, wherein processing the desired value comprises using a model to determine the setting of at least one production device.

10. The method of claim 8, comprising generating a display of a wellbore layout and a first value for the at least one production parameter corresponding to the wellbore layout.

11. The method of claim 8, comprising providing the script to the operator, wherein the operator cannot modify the script.

12. The method of claim 11, wherein providing the script to the operator comprises transmitting the script via a communication network.

13. The method of claim 11, wherein providing the script to the operator comprises transmitting the script via a portable memory device.

14. The method of claim 8, wherein the at least one production device is selected from the following group:

valves, chokes, and chemical treatment devices.

15. A method for controlling flow of formation fluid into a production wellbore, comprising:

measuring values of at least one production parameter at a plurality of production device over a length of the production wellbore, the production parameter relating to production of formation fluid comprising at least one of oil and gas from a formation into a production tubular at a selected depth;

displaying, at a user interface, a first chart showing along an axis a status indicator representing the plurality of production devices over a length of the production wellbore and indicating their status, the first chart further showing along the axis the measured values obtained at the plurality of production devices at a selected time;

displaying, at the user interface, a second chart showing the measured values over time at a selected position;

graphically manipulating the measurements in the first chart to indicate a desired value for the at least one production parameter at a selected location;

using a model to generate a sequence of settings for at least one production device in the wellbore, wherein the sequence of settings corresponds to the desired value for the at least one production parameter;

generating a script that includes the sequence of settings;

providing the script to an operator, wherein the operator cannot modify the script and the script is configured to run by receiving a command from the operator; and

implementing the script without modification to change a setting of the at least one production device upon receiving the command from the operator, wherein the at least one production device comprises a production device that is controlled to regulate a flow of a formation fluid from a formation into the production tubular.

16. The method of claim 15, comprising generating a display of a wellbore layout and a first value for at least one production parameter corresponding to the wellbore layout, wherein the model uses the desired value to determine the sequence of settings.

17. The method of claim 16, wherein the wellbore layout includes a status indicator to display current settings of the one or more production devices.

18. The method of claim 15, wherein providing the script to the operator comprises transmitting the script via a portable memory device.

19. The method of claim 15, wherein providing the script to the operator comprises transmitting the script via a communication network.

20. The method of claim 15, wherein the one or more production devices are selected from the following group:

valves, chokes, and chemical treatment devices.
