Abstract

The present disclosure relates to dynamically incorporating and economically validating drilling decisions. A computer system having a memory and central processing unit is provided and a knowledge store residing in the computer system is populated with data. The data may include surface drilling parameter data, bottomhole assembly data, bit records, measurement-while-chilling data, logging-while-drilling data, drilling event data, and lessons learned data. The data may be correlated data from one or more offset wells. One or more computerized static or dynamic contextual earth models are provided and used to dynamically incorporate and economically validate the drilling decisions. The one or more earth models can be updated in real-time.

Claims

1. A method, comprising:

providing a computer system having a memory and central processing unit;

populating a knowledge store residing in the computer system with data;

providing one or more computerized contextual earth models; and

using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions.

2. The method of claim 1, wherein the data comprise correlated data from one or more offset wells.

3. The method of claim 2, wherein the correlated data arc correlated by one or more of formation, depth, and time.

4. The method of claim 1, further comprising tracking a position of a well with respect to the one or more earth models.

5. The method of claim 1, wherein the one or more earth models are updated in real-time.

6. The method of claim 1, further comprising providing a real-time data link, and streaming the data in real-time using the real-time data link.

7. The method of claim 1, further comprising importing a drilling risk prediction model.

8. The method of claim 1, further comprising evaluating at least one of the cost and risks for a plurality of possible drilling scenarios;

and selecting a scenario from the plurality of possible drilling scenarios that optimizes a field development drilling plan.

9. The method of claim 1, further comprising performing a collision avoidance analysis.

10. The method of claim 1, wherein using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions comprises monitoring execution of a drill plan in real-time.

11. The method of claim 1, wherein using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions comprises weighing a projected cost of additional drilling against a potential additional recovery of producible material.

12. The method of claim 1, wherein using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions comprises minimizing geologically driven risk by visualizing the risks in the context of the earth models, and monitoring the impact of changes in geology interpretation on the drilling process.

13. The method of claim 1, wherein using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions comprises computing optimized well trajectories.

14. The method of claim 1, wherein using the one or more computerized contextual earth models to dynamically incorporate and economically validate one or more drilling decisions comprises at least one of using bidirectional workflows and analyzing multiple case scenarios.

15. The method of claim 1, wherein populating the knowledge store comprises at least one of:

incorporating historical data from multiple sources in multiple formats;

connecting to a real-time data source and streaming data; and

correlating multiple sources of data in different formats.

16. The method of claim 1, further comprising performing cross-discipline collaboration.

17. A system having a computer-readable medium having a set of computer-readable instructions encoded thereon that, when executed, perform acts comprising:

populating a knowledge store residing in the system with data;

representing one or more computerized contextual earth models; and

dynamically incorporating and economically validating one or more drilling decisions.

18. A method to perform well drilling operations, comprising:

collecting real-time drilling data;

generating a drilling data knowledge store using at least the drilling data; and

planning a well using the drilling data knowledge store.

19. The method of claim 18, further comprising displaying the real-time drilling data to show a plurality of correlated offset wells simultaneously.

20. The method of claim 18, further comprising displaying the collected drilling data within the context of a shared earth model.
