FDE drilled the PTH-2 well to 3,655 m in Lorraine, recording dissolved-hydrogen concentrations up to 49.6 percent; flow tests with SYSPROG and resource certification are the next critical steps.
La Française de l’Énergie recently drilled the PTH-2 exploration well to approximately 3,655 metres in the Moselle basin of Lorraine, reporting dissolved-hydrogen concentrations of 36.1 percent at 2,242 metres and 49.6 percent at 2,426 metres, according to the company. Those readings represent the principal data points returned from the borehole so far. They were recorded during the campaign that targeted deep formations beneath the former coal-mining district. The company has framed the results as an early indicator of hydrogen enrichment at depth, while noting that further work is required to characterise the resource and its behaviour over time.
