About the cover: Beecroft-Danwell Co. LLC drills a 5-inch
steel well with its Derex 1340-12 DR (dual rotary) drill rig in June
2022 in Lake Nebagamon, Wisconsin. The company was asked to
drill there after another water well contractor tried to drill a well
with a cable tool rig but was unsuccessful. The well was finished
open bottom/natural bottom in gravel. The static water table was
at 28 feet and the pumping level was at 75 feet pumping at a rate
of 10 gallons per minute. Total well depth was 222 feet deep with
5-inch casing from surface to 222 feet deep. To read more about the
advantages of the dual rotary drilling method, see page 21. Photo
