In December 2005, ARS was contracted by a Danish engineering company to apply Pneumatic Fracturing at two separate industrial sites near Copenhagen to demonstrate the technology’s applicability in creating fracture networks in the local surficial geology. Fracturing was also performed to facilitate the delivery of reagents or substrate for insitu remediation. The first site consisted of a clayey till material. ARS fractured at the depth of approximately 10 feet bgs to 26 feet bgs. Tracer dyes were injected to evaluate the fracture propagation. The fracture operation was carried out smoothly and observations indicated effective fracturing of the formation. The results of this project are being presented at the Battelle Chlorinated Conference in May of this year.

The second site was part of a biostimulation pilot study in which molasses was injected after Pneumatic fracturing was applied to a “gytje” formation. The long-term effect is being monitored by the site consultant.

ARS’ work attracted widespread interest from both the Danish government, academia and media personnel along with regional interest from other Scandanavian countries. Based upon the success at the sites, ARS is looking forward to future fracturing projects in Norther Europe.
