Geothermal Team Applies New Approach

Three papers (Spycher et al., Peiffer et al., and Wanner et al.) by the same team of ESD geochemists are to appear in the July 2014 issue of Geothermics.

Numerical Model Assesses Nevada Geothermal Area

Christoph Wanner recently led a team of ESD scientists in developing a new reactive transport model of the Dixie Valley, Nevada, geothermal region, aiming to assess fluid flow pathways and fluid rock interaction processes at the site.

Optimized Geothermometry for Geothermal Exploration

ESD’s Loic Peiffer recently led a team of ESD scientists in exploring a new geothermometry approach as a tool for inferring geothermal reservoir temperatures (the key in evaluating how productive a geothermal source could be).

Integrated Solute Geothermometry

Team of ESD geochemists revisits the mineral saturation index geothermometry method with the objective of simplifying its application and improving predictions of geothermal reservoir temperatures using numerical optimization.

Isotope Modeling as Bioremediation Tool

Jennifer Druhan and others incorporated the stable isotopes of sulfur within a reactive-transfer code to model the range of microbially mediated redox processes affecting isotope fractionation—potentially important for bioremediation.

LBNL and JAEA Reach Nuclear-Energy-Related Agreement

LBNL and JAEA reached an agreement to collaborate on developing “a methodology to evaluate the impact of geological disposal on the living environment (surface environment) and environmental safety science”

Rifle Snowmaking in the Name of Science

Ken Williams recently custom-generated snow at DOE’s Rifle, CO, site, as part of an effort to measure the level of snowmelt infiltration into soil and groundwater at the site.
