Abstract
Well systems comprise communicating devices for use in subterranean formations. An example well system comprises a mud valve system having a stator and a rotor to modulate drilling mud flow to provide increased pulse amplitude signals up-hole for improved and faster signaling from down-hole tools while also providing for better detection capability up-hole. The improved signaling technique permits for deeper well applications.
