SUTRA model used to evaluate Saline or Brackish Aquifers as Reservoirs for Thermal Energy Storage in the Portland Basin, Oregon, USA

June 17, 2020

This archive documents five 30-year SUTRA simulations summarized in Burns at al. (2020), and provides output from one short (2-year) simulation to allow verification that the archive model code runs properly. A modified version of SUTRA 2.2 was used to evaluate Reservoir Thermal Energy Storage by simulating layered system conditions (grid spacing varies depending on simulation run time to prevent boundary effects). This version of SUTRA is summarized in Burns et al. (2015), but in short, the primary differences from the current public-release version (v3) are that cell-by-cell thermal and hydraulic properties can be defined (allowing representation of the layered Portland system) and viscosity and density of water are defined with non-linear relations, giving improved equations of state for a wide temperature range. Code authors anticipate the functionality used for this work will be released as v4 of SUTRA. This USGS data release contains all the input and output files for the simulations described in the associated journal article (https://doi.org/10.1016/j.geothermics.2020.101877).
