Abstract
A computing system can be used to control concurrent wellbore operations. For example, the computing system can receive a process variable value of a process variable for two or more wellbore operations. The process variable may be a parameter of each of the two or more wellbore operations that is dependent on a manipulated variable of each of the two or more wellbore operations. The computing system may further receive a constraint. The constraint may include a maximum process variable value. The computing system may then determine, based on the constraint and the process variable value for each of the two or more wellbore operations, a manipulated variable value of the manipulated variable for each of the two or more wellbore operations. Additionally, the computing system can control the two or more wellbore operations using the manipulated variable value for each of the two or more wellbore operations.
