Environmental Horizontal Well Screens Solve Subslab Problems
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.
Engineered horizontal screens are the lifeblood of effective in situ remediation
systems. A successful screen design achieves the necessary balance of screen dimensions and operational parameters, and is appropriately tuned to material properties of the various media involved, to achieve uniform delivery or extraction of sufficient volumes of fluid or gas to effectively remediate the target zone.
Pilot testing and subsurface characterization provided data enabling Directional Technologies to design two horizontal air sparge wells and one horizontal soil vapor extraction well.
