ARSD 74:12:02:04. Minimum spacing of oil wells

In the absence of an order by the board setting spacing units for a pool, a well drilled for oil may not be drilled on any tract of land other than a governmental quarter-quarter-section, a governmental lot corresponding to it, or, in areas not covered by U.S. public land surveys, an arbitrarily designated 40-acre tract. The well must be located not closer than 500 feet to any boundary line of the governmental quarter-quarter-section, the governmental lot corresponding to it, or the arbitrarily designated 40-acre tract nor closer than 1,000 feet to the nearest well drilling to, or capable of producing from, the same pool. If the governmental quarter-quarter-section, governmental lot, or arbitrarily designated tract contains less than 35 acres, a well may not be drilled on it except with the written permission of the secretary after utilizing the notice of recommendation procedure in chapter 74:12:09.
