Established in 1965, Wallis Drilling is an Australian-based family-owned business operating a fleet of drilling rigs in Australia and selected international markets.
In 1974, while looking for a way to increase productivity and avoid sample contamination which was an issue in auger drilling, the company designed and built a completely new method of drilling - the Wallis Aircore system. The Aircore technology is now used all over the world, and was the first commercially successful Air Reverse Circulation drilling system in the world.
