October 2010 – Salt Water Creek Hope Island

Global Directional Drilling Services was contracted by Tenix Networks Pty Ltd for the installation of a of a 200mm enveloper pipe to house a gas line. The drill shot was at a length of 400m through marine sand to coffee rock and sandstone. Due to unstable ground conditions at the start and finish of the bore we need to trail rods in case of bore hole collapse. Due to lack of access and environmental constraints a exit side recycle system was used to clean drilling fluid before it was pumped via a return line back to entry side recycler, which then fed the drilling rig with clean fluid. This practice saved water and the disruption of traffic was kept to a minimum. The project was completed with no incidents.
