Engineered, custom slotted horizontal wells are designed on a site-by-site basis, specifically for the subsurface conditions and remedial application desired. Prefabricated horizontal wells systems are available for purchase from the manufacturers.
The Australasian Land and Groundwater Association, ALGA, recognized Pedro Balbachevsky, AECOM, and his team, Directional Technologies and Matrix Drilling, for the 2018 Outstanding Innovation Award for Australia’s 1st Installation of Horizontal Wells for ISCO and Biosparging.
Our long-time client, FPM Remediations, Inc., used their knowledge of horizontal biosparging wells to design a unique and efficient remediation system to allow for uninterrupted taxiing of commercial and military aircraft.
Faced with the urgent need to remediate beneath an active runway at John F Kennedy International Airport in New York City, Lou Fournier, Ph.D. of Star Environmental, Inc. contacted Directional Technologies, Inc. to install the first horizontal wells using mid-sized directional drilling rigs. His innovative approach to this pivotal project helped create the horizontal remediation industry as we know it today.
To avoid costly business interruption and site disturbance, a non-invasive remedial approach by installing horizontal ozone sparge wells with directional drilling techniques was recommended.
This case study discusses how a horizontal groundwater extraction well helped remediate an extensive carbon tetrachloride plume beneath multiple residences and a recreational area.
Installation of horizontal remediation wells with directional drilling prevented an estimated 200 hours of manufacturing downtime.
To achieve the remedial goals for the consultants and their client, horizontal wells were used as the solution. They provided an alternative to typical remedial technologies with less of an impact to both the site and the general public.
Directional Technologies installed horizontal injection wells, which enabled in-situ chemical oxidation (ISCO) injection with zero interruption to business and customer traffic.
At challenging sites where decades of remediation will be required rather than years, Directional Technologies can install stainless steel horizontal remediation wells (HRWs) due to the longevity the stainless steel horizontal well material provides.
