The Carter coordinate is written by specifying a pair of footages from the one-minute section boundaries and the reference boundary (north, south, east, or west) for each, the one-minute section number, the five-minutes quad letter, and the five-minute quad number. Within the one-minute section, the location is pinpointed by specifying the distance from an adacent pair of one-minute section boundaries to the well.
Each five-minute by five-minute quad is further subdivided into 25 one-minute by one-minute sections. The quads are assigned numbers (equivalent of the range) beginning with zero (0) in the west and increasing to 92 in the east. These quads are assigned letters (equivalent of the township) beginning with'A' in the south and increasing through 'Z' and 'AA' to 'GG' northward. The State is divided into a regular grid with each cell (or 'quad') being five minutes of latitude by five minutes of longitude. The system was developed by the Carter Oil Company to mimic the township and range location system in areas that had not been surveyed. The Carter coordinate system is a grid, based on latitude and longitude, used to locate oil and gas wells in Kentucky.
