Danny Kingham, Shailee Bhattacharya, Christ Niamike, Noah Goodkind, and Travis M. McGuire recently co-authored “Is your state regulation ready? a review of geologic carbon sequestration regulations in the United States.”

Co-authored with William Gallin, Paul V. Franke, Meghan E. Gavin, Emma Thomley, and Ryan Kammer, and Ian Sackmann, the article reviews geologic carbon sequestration regulations across all 50 states using 14 regulatory factors tied to project advancement, from pore space ownership and liability to Class VI primacy and pipeline considerations.

The result is a practical framework for evaluating regulatory readiness, offering insight for states and other entities looking to develop or strengthen geologic carbon sequestration policy. It also highlights how regulatory readiness often aligns with Class VI primacy, energy production history, and experience with federally supported projects.

This publication reflects the technical and policy-focused work GSI brings to complex carbon management challenges.

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.
