Produced water samples serve as a proxy for groundwater samples, although there
is some bias and uncertainty introduced, both because these are water samples from
the oil and gas fields, and because of the uncertain sampling methods and analyses.
There are distinct chemical trends in the deep basin groundwaters, which are
controlled by the flushing of meteoric water through high permeability formations.
Piper diagrams show that produced water samples from nearly all formations show
signs of halite dissolution.
Brine origins were determined using ion ratios, dividing samples into genetic
classifications of connate brines, saline meteoric waters, and a mixture of the
