Abstract

Techniques for adaptively performing an operation in a well system that include determining, using a control sub-system, an operation schedule that indicates control action steps in the operation; instructing, using the control sub-system, the well system to initiate a first control action step of the operation that transitions a first fluid valve from a first current valve state to a first target valve state; determining, using the control sub-system, whether an expedited performance parameter associated with the operation is set in the operation schedule; and in response to determining that the expedited performance parameter associated with the operation is set, instructing, using the control sub-system, the well system to initiate a second control action step of the operation that transitions a second fluid valve from a second current valve state to a second target valve state before the first fluid valve achieves the first target valve state.

What is claimed is: 
     
         1 . A method of adaptively performing an operation in a well system, comprising:
 determining, using a control sub-system of the well system, an operation schedule that indicates control action steps in the operation;   instructing, using the control sub-system, the well system to initiate a first control action step of the operation from the operation schedule that transitions a first fluid valve from a first current valve state to a first target valve state;   determining, using the control sub-system, whether an expedited performance parameter associated with the operation is set in the operation schedule; and   in response to determining that the expedited performance parameter associated with the operation is set in the operation schedule, instructing, using the control sub-system, the well system to initiate a second control action step of the operation from the operation schedule that transitions a second fluid valve from a second current valve state to a second target valve state before the first fluid valve achieves the first target valve state.   
     
     
         2 . The method of  claim 1 , comprising, in response to determining that the expedited performance parameter associated with the operation is not set in the operation schedule:
 determining, using the control sub-system, whether the first fluid valve has achieved the first target valve state based on sensor feedback received from an equipment sensor associated with the first fluid valve before a sensor timeout elapses; and   instructing, using the control sub-system, the well system to perform the second control action step of the operation to transition the second fluid valve from the second current valve state to the second target valve state at an earlier of the sensor feedback indicating that the first fluid valve has achieved the first target valve state and the sensor timeout elapsing.   
     
     
         3 . The method of  claim 2 , comprising indicating, using the control sub-system, that the equipment sensor associated with the first fluid valve is potentially faulty in response to determining that the sensor timeout elapsed. 
     
     
         4 . The method of  claim 1 , comprising, in response to determining that the expedited performance parameter associated with the operation is set in the operation schedule, instructing, using the control sub-system, the well system to initiate a third control action step of the operation from the operation schedule that transitions a third fluid valve from a third current valve state to a third target valve state before the second fluid valve achieves the second target valve state.
