Abstract

A method can include receiving a digital well plan; issuing drilling instructions for drilling a well based at least in part on the digital well plan; comparing acquired information associated with drilling of the well with well plan information of the digital well plan; and outputting results based at least in part on the comparing of the acquired information with the well plan information.

Claims (31)

1. A method comprising:

receiving a digital well plan;

issuing drilling instructions for drilling a well based at least in part on the digital well plan;

comparing acquired information associated with drilling of the well with well plan information of the digital well plan to determine if there is at least one deviation from the digital well plan; and

upon determining that there is the at least one deviation, inputting the at least one deviation to a trained machine model to electronically generate results that include at least one outcome that is associated with the determined deviation and instructions to adjust the digital well plan based on the at least one outcome.

2. The method of claim 1 , wherein the digital well plan comprises at least one member selected from a group consisting of a trajectory factor, a bottom hole assembly factor, and an operational factor.

3. The method of claim 1 , wherein determining if there is the at least one deviation includes determining if there is a difference between the acquired information and the well plan information.

4. The method of claim 3 , wherein the comparing comprises performing a search of a database utilizing the difference as a query, wherein the search generates results, wherein the results comprise the at least one outcome.

5. The method of claim 1 , further including training the trained machine model based on the at least one outcome that is classified as being beneficial that is associated with a shorter period to drill the well than planned.

6. The method of claim 1 , further including training the trained machine model based on the at least one outcome that is classified as being determinantal that is associated with a longer period to drill the well than planned.

7. The method of claim 1 , wherein the at least one deviation pertains to at least one of: an equipment, an operation of equipment, and timing of operations of equipment.

8. The method of claim 1 , comprising analyzing the at least one deviation to determine at least one factor of the digital well plan as being at least in part an underlying cause of the at least one deviation.

9. The method of claim 1 , wherein the at least one deviation comprises a difference in a rate of penetration of the drilling or a difference in a dogleg of a wellbore of the well.

10. The method of claim 1 , comprising analyzing the at least one deviation to identify at least one factor specified in the digital well plan as being associated with the at least one deviation, wherein the at least one factor comprises at least one of an equipment factor, an operational factor and a formation factor.

11. The method of claim 1 , wherein the instructions to adjust comprise providing instructions to control at least one piece of equipment to adjust a drilling operation based on a classification of the at least one outcome.

12. The method of claim 1 , further including receiving information for the well, selecting one or more offset wells, accessing comparison results for the one or more offset wells, and generating the digital well plan based at least in part on at least a portion of the comparison results for the one or more offset wells.

13. A system comprising:

a processor;

memory accessible by the processor;

processor-executable instructions stored in the memory and executable to instruct the system to:

receive a digital well plan;

issue drilling instructions for drilling a well based at least in part on the digital well plan;

compare acquired information associated with drilling of the well with well plan information of the digital well plan to determine if there is at least one deviation from the digital well plan; and

upon determining that there is the at least one deviation, input the at least one deviation to a trained machine model to electronically generate results that include at least one outcome that is associated with the determined deviation and instructions to adjust the digital well plan based on the at least one outcome.

14. The system of claim 13 , wherein the digital well plan comprises at least one member selected from a group consisting of a trajectory factor, a bottom hole assembly factor, and an operational factor.

15. The system of claim 13 , wherein the trained machine model is trained based on the at least one outcome that is classified as being beneficial that is associated with a shorter period to drill the well than planned.

16. The system of claim 13 , wherein the trained machine model is trained based on the at least one outcome that is classified as being detrimental that is associated with a longer period to drill the well than planned.

17. The system of claim 13 , wherein the at least one deviation pertains to at least one of: an equipment, an operation of equipment, and timing of operations of equipment.

18. The system of claim 13 , wherein the at least one deviation comprises a difference in a rate of penetration of the drilling or a difference in a dogleg of a wellbore of the well.

19. The system of claim 13 , wherein the instructions to adjust comprise providing instructions to control at least one piece of equipment to adjust a drilling operation based on a classification of the at least one outcome.

20. The system of claim 13 , wherein the system is instructed to receive information for the well, select one or more offset wells, access comparison results for the one or more offset wells, and generate the digital well plan based at least in part on at least a portion of the comparison results for the one or more offset wells.
