Control module system for a subterranean well

摘要

A control module system provides convenient and economical operation of downhole tools, which operation is controllable from a remote location. The control module system includes a control circuit (46) configured to control selective opening of a plurality of valves interconnected between a plurality of accumulators (36) and multiple tools (14), all positioned within the well. Additionally, the control circuit (46) communicates with a terminal (44) at the earth's surface for transmitting instructions from the terminal to the control circuit, and for transmitting data from the control circuit to the terminal. <IMAGE>
