We have drilled and installed 3 times* the number of monitoring wells around Mackay compared to any other drilling company still operating.   Why?  Because our team uses the right equipment with the right processes and the right methods for the right reason by utilising wisdom, judgment and discretion in the pursuit of your project’s goals.  (*May 2019 Queensland Spatial Data extract)


Are you researching monitoring bores in the Mackay, Bowen, Proserpine, Sarina or Bowen Basin areas? 

Try out our new Google MyMaps page that displays known and logged wells in the regions.  There is a link in each well description to the full DNRM bore log and you DON'T have to use Qld Globe, at all, ever. :)


We use and recommend Solinst water level data loggers and depth meters.
