Webster Drilling

Request

Webster Drilling were awarded a contract early in 2009 for drilling services on the Gorgon LNG Project CO2 re-capture program. This was a very challenging project as Gorgon LNG is being built on Barrow Island, a class A nature reserve.
  
The project involved the drilling of just under 1000 holes as a part of a 3 dimensional seismic survey which will be repeated at intervals during the term of the project. This program will be to monitor the growth of the CO2 gas that will be stripped from the Gorgon gas and injected into a geological structure beneath the island. To conform to the project requirements and the strict environmental protocols all equipment is either custom built and / or modified accordingly.

To execute this project Webster Drilling needed to build special light weight drill rigs which could be moved around site via helicopter. All equipment needed to pass stringent quarantine inspections which included pesticide fogging and wrapping in cling film. Seven drill rigs were required, six for operation and one for standby along with operators and service technicians. Each drill rig required one 350 cfm compressor (Atlas Copco model XAVS340) to run the drill. All compressors were fitted into specially made and certified heli-sling lifting frames to facilitate placement at each drill site.
