[pdf] An automated drill rig (ADR) is an automated full-sized walking land-based drill rig that drills long lateral sections in horizontal wells for the oil and gas industry. ADRs are agile rigs that can move from pad to pad to new well sites faster than other full-sized drilling rigs. Each rig costs about $25 million. ADR is used extensively in the . According to the "Oil Patch Daily News", "Each rig will generate 50,000 man-hours of work during the construction phase and up.
