Abstract: A system and method that include receiving a digital well plan and issuing drilling instructions for drilling a well based at least in part on the digital well plan. The system and method also include 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. The system and method additionally include performing a search of a database upon determining that there is the at least one deviation, wherein the search generates results that comprise at least one outcome that is classified as being a positive outcome or a negative outcome. The system and method further include training a neural network as a machine learning model based on the results to electronically adjust the digital well plan to increase a likelihood of at least one positive outcome.

The system and method additionally include generating at least one well plan that is based on the constraints and the set of points for constructing a well associated with the wellbore. The system and method further include transmitting the at least one well plan to a drilling system to execute the at least one well plan to control drilling equipment to construct the well.

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.

Abstract: An improved approach to creating a plan for a well. A user receives an initial well plan for a planned well and uses the initial well plan as a starting point for alternate well plans. This is done by creating a copy of the initial well plan, allowing the various uses to make changes to the initial well plan, and executing various automatic validation routines on the alternate designs. These validation routines can provide estimated times and costs to complete the planned well use the alternate well plan. The approach can also involved displaying the estimated times and costs of the different candidate well plans. The user can then select one of the candidate well plans as the master well plan. As replanning is done during the operations, this replanning information, along with the actual executed actions, is captured and stored.
