DTD has completed the installation of a well at a EPA Superfund Site

Posted on

The well design (very low screen open area and multiple casings) required the use of our American Augers 210,000 lbs-rated drill rig and 100% biodegradable drilling fluid. After assembly of the complicated pull-back package (multiple screens and casings) the well was drilled, installed and developed over two weeks
in July.

The screened interval was set 100 feet below ground and designed to allow oxygen injection into any of three distinct 170-ft long intervals. One of the three screened intervals was designed by Air Diffusion Systems (, marking DTD’s first installation of this product.
