The process of a blind installation for a horizontal well eliminates the need for an exit point. Instead, the well bore is terminated in the subsurface at the far end of the proposed screen and the well material is pushed into place.
Due to their increased screen length and geometric compatibility, Horizontal Wells present an advanced solution to hydraulic control applications.
The budget is always a critical driving factor for remedial decisions, so let’s talk about money. At a basic level, it is almost always less money to install one vertical well versus one horizontal well; but by which parameters are we making this comparison.
Horizontal remediation wells (HRWs) are often most associated with accessing inaccessible areas of a site, such as beneath active buildings, railroads, roadways, and more. Though useful in these situations, the benefits of HRWs go far beyond accessibility.
Directional Technologies takes a personalized, site-specific approach to all environmental projects, with the goal of partnering with environmental consultants to increase the remedial effectiveness at their site through the use of HRWs.
Horizontal drilling techniques offer significant advantages when delineating contamination, particularly on environmental projects where contamination exists in limited-access locations. Several tools can be applied to horizontal technologies to ensure the contamination at the site is well-defined, such as horizontal soil sampling and the use of down-hole sensing.
Directional Technologies provided horizontal well design alterations for successful remedial results at a bulk fuels facility in North Carolina. Even at highly characterized and delineated sites, physical site restrictions can prevent the ability to implement proposed remedial designs successfully.
While many directional drilling companies exist and do an excellent job installing subsurface utilities, Directional Technologies specializes in designing, drilling, and installing horizontal remediation wells. Even for the most experienced environmental consultants, utilizing a foreign technology can be an intimidating endeavor – particularly when remedial expectations of the client are a high priority.
Targeting non-aqueous phase liquid (NAPL) hotspots with horizontal remediation wells is an effective way to enhance remediation and prevent downgradient plume migration. Groundwater contamination plumes sometimes separate into several individual zones, creating additional challenges for remediation and increasing the likelihood of off-site migration.
Physical site constraints, in combination with shallow groundwater, have led more consultants to target exposure pathway elimination with horizontal remediation wells. Gas stations are one of the most common facilities requiring a remedial response due to compromised underground storage tanks (USTs) and leaks resulting from fuel dispenser piping failures.
