Method for controlling fluid production from a wellbore by using a script
First Claim
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.

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.

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. - View Dependent Claims (9, 10, 11, 12, 13, 14)

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. - View Dependent Claims (16, 17, 18, 19, 20)
