Lisa Molofsky, PhD, PG has co-authored a new article titled “A combined 228Ra/226Ra and 87Sr/86Sr approach to identify the production of out-of-zone formation fluid from Marcellus shale gas wells,” published in Applied Geochemistry.

This article, co-authored with M.A. Engle, T.W. Wagner, A.S. Wylie, and D.P. Fernandez, presents a geochemical method that combines radium and strontium isotope ratios to determine the origin of high-salinity fluids produced from Marcellus shale gas wells. The study provides valuable insights into identifying out-of-zone water production and offers a framework that could be applied to other oil and gas basins.
