A method and system for surface production of gas from a subterranean zone includes lowering reservoir pressure in an area of a subterranean zone having a medium to low effective permeability through a multi-branching well bore pattern. A repeater recovers signal levels of the third and fourth internal clocks and outputs the third and fourth internal clocks as DLL clocks. Feature points of one of the images and those of the other image or images are compared to each other to effect matching.
