  • Patent number: 11790320
    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.
