Optimizing completion operations

A system for optimizing a completion operation, comprising:

• an interface to equipment and sensors for performing the completion operation, wherein the interface supplies control signals to the equipment and obtains measurement signals from the sensors;
• at least one short-term optimizer module that derives a current job state based at least in part on the measurement signals, and that further adjusts the control signals to optimize a short-term cost function, the short-term cost function comprising:
• short-term risks and short-term rewards;
• and
• a difference between the current job state and a desired job state derived from optimized values of a set of decision variables;
• and
• a long-term optimizer module, coupled to the at least one short-term optimizer module, that determines the optimized values based on a long-term cost function, the long-term cost function comprising long-term risks and long-term rewards and accounting for at least a long-term reward and a final state cost, wherein:
• the control signals control completion operation equipment;
• the short term-risks are promoted to long-term risks when the short-term risks persist over a threshold time period;
• and
• the short-term rewards and risks and the long-term rewards and risk comprise non-financial rewards and risks.
