Benefits Of Horizontal Wells

BARRIER AIR SPARGING

Why Air Sparging?
Quick Refresher: air sparging (AS) is a proven groundwater remediation technique that removes volatile organic compounds (VOCs) from groundwater by injecting air into water-saturated formations. There are two common approaches to AS. The first involves injecting air through wells into the impacted area to remediate the plume. The second creates a transport barrier by sparging downstream from the impacted zone, VOCs are removed as the groundwater passes through the sparge barrier and aeration enhances natural attenuation.

Site Remediation Using Horizontal Air Sparge (AS)/ Soil Vapor Extraction (SVE), and Multiphase Extraction (MPE) Wells

At the Florida Remediation Conference, Directional Technologies discussed the following horizontal well presentation: “Site Remediation Using Horizontal Air Sparge (AS)/Soil Vapor Extraction (SVE), and Multiphase Extraction (MPE) Wells”, Narayanan Raghupathi, P.E. and Angela Finney, MACTEC.

The presentation focused on a historically challenged site located in Tallahassee, Florida, that was remediated by using two horizontal soil vapor extraction wells and two horizontal air sparging wells. Benefits of horizontal wells at this site included that all business activities were able to be continued in their normal routine at this busy gas station during the remedial construction.

Using Horizontal Extraction Wells to Contain Chlorinated Compounds Near Landfills

Challenge

Vertical wells at the landfill required individual submersible pumps, water level controls, flow meters, and force mains. Each vertical well suffered from mineral deposits, incrustation, and sediment buildup over the years.

Horizontal Soil Sampling in Inaccessible Areas at Former Power Plant Site

Horizontal Soil Sampling in Inaccessible Areas at Former Power Plant Site

Horizontal soil sampling has been conducted by Directional Technologies since 1992. The first horizontal soil sampling project was the successful collection of 8 soil samples beneath sensitive infrastructure. The company’s experience in horizontal soil sampling includes sampling in a wide variety of soils.

Soil samples were required in areas that were not accessible with vertical drilling methods to delineate the extent of impacts at a former power plant. To overcome the challenging site access restrictions, horizontal sampling techniques were used. This included sampling 6 locations with horizontal drilling technology to complete subsurface investigation activities.

Horizontal Remediation Well Workshop in Chicago

Directional Technologies a global leader in Horizontal Remediation Well (HRW) technologies and Horizontal Directional Directional Drilling (HDD), hosted a Horizontal Remediation Well Workshop in Chicago, Illinois. HRW technology has improved significantly over the past five years. The workshop discusses improvements in horizontal technology and how it can be applied to improve site clean-up. Course topics and discussions included onsite considerations when using horizontal wells versus vertical wells, soil vapor extraction with horizontal wells, In Situ chemical oxidation, drilling fluids, and blind versus continuous horizontal remediation wells.
