As of the 1st November, Devico became proud majority owners of the Perth based business, further solidifying a long running relationship and commitment to deliver innovations in directional drill hole surveying to Australia and across the world.

As Australia’s distributors of Devico’s downhole surveying products, Downhole Surveys’ beginnings resemble a similar parallel to that of Devico’s. For founder and CEO Mike Ayris, the concept to form a directional surveying business began in 1989 when he was working as a draftsman on a WA mine site and began testing the theory that all vertical drill holes are drilled straight. Just as Viktor Tokle was inventing solutions for what was a time-consuming process in steerable coring, Ayris sought out to prove that all drill holes do in fact deviate and consequently, Downhole Surveys was born.

Adopting very similar values and ideals, despite their different geographical locations, both Devico and Downhole Surveys pride themselves on delivering continuous improvement to their respective fleets of products and software, always placing the value of quality, consistency, precision and integrity at the forefront of their operations.

Mike Ayris continued to build the company from the ground up, from just one man and a film-based Multishot, to now operating out of bases in Perth and Kalgoorlie, it’s Downhole Surveys’ technical knowledge and experience, paired with extensive research and development that has led the company to introduce over 15 different surveying products and innovations to the Australian mining and drilling industry, a number that continues to grow.

Whilst business at Downhole Surveys will continue to run as usual, the partnership which Ayris describes as ‘a perfect fit’, provides considerable opportunity for knowledge exchange. ‘Through a collaborative research and development approach, the group will see some exciting new products in directional surveying and directional drilling released over the next few years’ (Ayris), with both companies very motivated by the prospect of expanding their offerings within the Australian and global markets.
