Abstract
Systems and methods for managing a loss circulation zone in a subterranean well include a tool housing located on a surface of a tubular member with a tool cavity that is an interior open space within the tool housing. An electromechanical system is located within the tool cavity and has a printed circuit board, a microprocessor, a sensor system, a power source, and a communication port assembly. A release system can move a deployment door of a deployment opening of the tool housing between a closed position and an open position. The deployment opening can provide a flow path between the tool cavity and an outside of the tool housing. The release system is actuable autonomously by the electromechanical system. A releasable product is located within the tool cavity and can travel through the deployment opening when the deployment door is in the open position.
