Effective October 1, 2005, Oil Drilling & Exploration (ODE) has changed its name to Ensign International Energy Services and is the international division of Ensign Energy Services Inc, Canada's largest international drilling contractor listed on the Toronto Stock Exchange with more than 300 drilling and workover rigs.

The Company provides services including drilling for oil, gas, geothermal energy and coal seam methane gas, the workover and servicing of existing wells and the supply of oilfield equipment and services.

The ODE name has been part of the Australian oil scene for more than 50 years and has been active internationally for more than 30 years. A name change is a significant step for many valued employees, both past and present, and for the Company's loyal and valued clients. Nevertheless the change is important to continue ODE's history and send a clear message that its history of service is now an integral part of a larger organisation thus providing added financial and technical strength. The Ensign group is focused on building its reputation through ongoing commitment to providing save and efficient oilfield services – internationally.

ODE will be known as Ensign International Energy Services with operations in each country registering a local Ensign name. All office contact phone/facsimile numbers will remain unchanged.
