EnLink has a dramatically better way to drill holes for large-scale EHXs. EnLink's fit-to-purpose drill rig, using proven technologies and optimized for large scale GHP projects, enables EnLink to efficiently drill small-diameter holes several hundred feet deep in a wide variety of soil conditions - even under extremely challenging conditions where casing would be required.

The EnLink Drill

With its technical talent developed over decades in oilfield and geotechnical services, EnLink met an industry challenge head-on and designed a "fit-to-purpose" drill rig specifically optimized for high production of GHP boreholes in any soil condition.

The patented EnLink drilling process is an important step in the evolution of the EnLink system: a suite of technologies exclusively focused on efficient design and installation of EHXs. EnLink's highly efficient loop insertion and grouting systems have been successfully utilized for over five years, and remain part of the EnLink system as they are integrated with the use of the EnLink drill.

Providers of drilling services on GHP projects typically use drilling equipment developed for other applications, mainly water well drilling. In EnLink's experience, these drilling technologies are not optimal for high production rate requirements (i.e., several hundred wells on a single site) associated with GHP installations for commercial/institutional sites.




The lack of a consistent solution to the drilling difficulties produce cost overruns and delays in large-scale GHP project completion, leading either to dissatisfied Enlink tisfied customers or abandonment of projects at the feasibility stage.
The EnLink Drill employs an innovative integration of components, including a multi-function drill head and automated rod/pipe handling and casing methods. The components have been individually demonstrated over many years in challenging applications. With EnLink’s proprietary design, the drill operator simply selects the correct features and tools for the job at hand and consistently achieves maximum production rates, no matter what soil condition is encountered.

 In commonly encountered unstable soil or overburden conditions, the EnLink Drill prevents the borehole from collapsing on itself by simultaneously inserting casing into the hole as the drill penetrates the earth, to ensure that the bored hole will remain open for the looping and grouting steps. The use of the EnLink Drill will provide greater assurance that drilling rates can be achieved in a wide variety of geologic conditions – mitigating common project delays and price adjustments as difficulties or changing geologies are encountered.

The EnLink Drill allows your projects to be competitively priced, because the EnLink System is cost-competitive in virtually any condition. We complete EHXs where other drillers cannot readily or economically perform.
