Abstract
A method for use with equipment located downhole in a subterranean well includes providing a model describing behavior of the equipment and measuring a state of the equipment downhole. An indication is received of the state at a surface of the well, and the model is modified based on the indication. The system includes a communication link, a circuit and a machine. The communication link is adapted to furnish an indication of a state of the equipment to the surface of the well. The circuit is located downhole and is adapted to detect the state and produce the indication. The machine is adapted to provide a model describing behavior of the equipment and modify the model based on the indication.
