Case Studies
In mid-February 2011, Drilcorp mobilized to the Science City site which was the old Newcastle Brewery Site adjacent to Newcastle’s St. James Stadium.
The objective is to drill a borehole to a depth of 2000 metres beneath the site to explore for hot water which, if found, will be used to supply the future energy needs of the site and possibly the surrounding area.

Due to rising water within mine workings a discharge has occurred within a block of coal associated the now abandoned Lancashire Coalfield, discoloured mine water was observed to arise from an old mine adit and discharging into the nearby watercourse of a local brook .
Drilcorp Ltd was commissioned by Coal Authority to drill and install a large diameter borehole within which to install a submersible pump and to utilise this borehole as an abstraction point to lower the water table in its surroundings and to reduce or stop pollution from the above mine.
The borehole is situated in open fields which will eventually be utilised for constructing a mine water treatment scheme in conjunction with the above abstraction borehole.
The work involved forming a 450m temporary access across an open field and a working area (on an incline) with aluminium track way so as to minimise damage to the grassland.

Getting heat out of the London Underground (LU) network is a huge engineering challenge and TFL has established a dedicated programme team to provide solutions to prevent temperatures on deepest parts of the network rising to unacceptable levels.
The need to avoid increasing temperatures on the Underground system is actually the flipside of TFL’s success. Services are planned to increase by 25%, and new trains, that can accelerate quicker, are on order. But moving more customers and more trains takes more energy, even when the best of modern technology is applied, and more energy creates more heat. And, controlling temperatures is harder than ever before, because the ground around the tunnels has heated up over the many years since they were built.
