WHY ARE DRAGON DRILLING SO SUCCESSFUL?
In 2005 development work was started on a drilling shoe specially designed for drilling through waste. The design was perfected in 2006 and patent GB 2426988 was granted on the 20th May 2007. By using a specialist drilling shoe, Dragon Drilling are able to drill deeper and more efficiently than other operators.
The use of a specialist drilling shoe, coupled with instrumentation on the drilling rig console and highly trained Lead Drillers, enables the drainage blanket to be identified as soon as the drilling shoe makes contact. The use of this equipment and drilling techniques has enabled Dragon Drilling to maintain the enviable record of never having penetrated the containment engineering on a landfill site.
In 2006 a drilling technique was developed that enabled the saturated waste from a borehole to be removed after the physical characteristics of the waste had been changed using a conditioning agent. Patent GB 2431177 was granted on 13th August 2008 for the conditioning of saturated waste from a borehole.
The ability to intercept the drainage blanket, coupled with the technique to remove saturated waste from depths of up to 70m, has enabled Dragon Drilling to install leachate boreholes on sites where conventional drilling techniques have repeatedly failed.
