This workshop addresses drilling, constructing, developing, and pump testing of high capacity water wells using open hole, air assisted reverse rotary, and large diameter casing advancement methods. Two recent projects conducted in southwestern Arizona will be shown at various stages so you can see how traditional methods were adapted for special application. The open hole well drilling contract called for 20-inch-diameter steel cased, gravel packed wells to be drilled to 1,000 feet. The casing advancement drilling contract called for advancing 20-inch-diameter steel casing to an average depth of 250 feet, installing 16-inch-diameter stainless steel screens. Both methods resulted in wells producing 3,000 to 4,000 gpm. You will learn how two very different projects produced nearly the same final results.
