400′ Horizontal Well Radius of Influence
Not a typical radius of influence for a horizontal well which is usually 80’ to 120’ perpendicular to each side of the well screen.

Where chlorinated solvents are the issue, horizontal wells enable soil vapor extraction (or multiple in situ chemical oxidation injections) and provide subslab depressurization with appropriately sized/controlled blower systems.
The Horizontal Remediation Well system effectively remediated the site within 18 months. The presentation takes you through the conceptual design and the horizontal well installation to the site closure.

Faced with a variety of subslab problems, environmental managers are turning to horizontal drilling technology.
Aggressive removal of dense non-aqueous phase liquid (DNAPL) tetrachloroethylene (PCE) and trichloroethylene (TCE) under an active manufacturing facility is the objective of an electrical resistance heating (ERH) system that was installed using horizontal drilling.
Directional Technologies designed/installed each air sparge well to deliver approximately 2 pounds per minute of oxygen to the subsurface, or a total of 4 pounds per minute.

Bentonite-based drilling fluid is hydrated ex situ and yields prior to commencing directional drilling; and
bentonite is a component of the directional drilling mud system, not the sole component.
