δ¹⁸O and δ²H in pore water, groundwater, and drilling fluid samples. Error bars represent the possible isotopic equilibrium fractionation difference for samples with less than 3 g water adapted from Hendry et al. [50]. The black line represents the local meteoric water line (LMWL), δ²H = 7.2δ¹⁸O + 5.7, from Alice Springs.
