The United States Well Spotting course builds on the information introduced in the U.S. Land Survey Systems (PDM-021) course. This class provides further knowledge on complex locations, particularly those in Texas and Ohio. We focus on how a well's position is located and described, or “spotted.” U.S. Well Spotting gives insight to much history that explains how the systems in Texas and Ohio evolved. We guide you through the process of placing a well on a map or locating a well that is already on a map. This course is a “must do” for anyone dealing with U.S. wells and their locations.
