South African borehole subsurface Targeted loci environmental
The South African borehole of interest is at a depth of 1.34 km (BE326 Bh2). This sub-horizontal borehole penetrates 57 meters into a medium to coarse-grained sub-lithic arenite to intersect a NNW striking fault zone where it encountered high-pressure water with a flow rate of 750 L min-1. Since it was first drilled in 2007, it has been sealed off with a high pressure steel valve. The brackish, alkaline paleometeoric water and microbial communities collected from this borehole were first characterized in 2011. PIs Cara Magnabosco and Tullis Onstott.
