We supported an oil exploration drill off Eucla, near the WA/SA border. Two S61Ns and we doubled the population: bore water for the settlement, and 1 litre of fresh water/day for 'personal' use.
That brings back memories. I was involved in exploration drilling in south-central Queensland in the 80s. One day, I was driving by an abandoned exploration well that had been completed as a water well in the Precipice Sandstone, which is the main reservoir in the Great Artesian Basin. In school in Britain in the 50s, I was fascinated by this source of water - I had visions of gushing springs of wonderful fresh water.
I parked, walked over to the well head and sampled the "bore water" via a convenient tap. It was disgusting - sulphurous and tasting of unpleasant mineral salts. It ruined my idyllic dream!
