Scientists Unveil New Version of Popular Flow-Simulation Tool

Scientists from the Energy Geosciences Division at Lawrence Berkeley National Laboratory (LBNL) have released the latest version of TOUGH (Transport Of Unsaturated Groundwater and Heat), a suite of software codes used worldwide to simulate nonisothermal multiphase flow and transport in fractured and porous media. TOUGH3 builds on the impressive legacy of its TOUGH predecessors, which…

New EESA Study Indicates Greater Capacity for Carbon Storage in the Subsurface

New research from the Energy Geosciences Division at Berkeley Lab shows that carbon dioxide can penetrate the inner layers of some non-swelling clay minerals which make up the dominant clays in the Earth's deep subsurface. Results of the work performed at the Center for Nanoscale Controls on Geologic CO2 (NCGC) and the national lab’s Molecular Foundry could help inform practices intended to help limit carbon dioxide emissions, such as carbon capture and storage (CCS) and enhanced oil recovery (EOR).

The Puzzle to Plugging the Worst Natural Gas Release in History

By the time Lawrence Berkeley National Laboratory (Berkeley Lab) scientists Barry Freifeld and Curt Oldenburg visited the Aliso Canyon natural gas storage facility in December 2015, the SS-25 well blowout had been leaking natural gas into the air for more than six weeks. The notoriously strong winds at Aliso Canyon carried the natural gas and its…

The BEST Field Projects Selected to Improve Water Management and Conservation

Example of 3D View permeability at TIW-1 relief well for BEST project.

Earlier in June, the Department of Energy announced the selection of two Brine Extraction Storage Test (BEST) field projects that will test enhanced water recovery technologies for their potential to produce useable water from carbon dioxide (CO2) storage sites. The projects are set to receive funding managed by the Department’s National Energy Technology Laboratory’s (NETL)…
