GEOPHIRES v2.0

⚠️ Deprecated

This version of GEOPHIRES is deprecated. Use GEOPHIRES-X instead.

GEOPHIRES v2.0 Description

GEOPHIRES v2.0 is a free and open-source geothermal techno-economic simulator. GEOPHIRES combines reservoir, wellbore, surface plant, and economic models to estimate the capital and operation and maintenance costs, instantaneous and lifetime energy production, and overall levelized cost of energy of a geothermal plant. Various reservoir conditions (EGS, doublets, etc.) and end-use options (electricity, direct-use heat, cogeneration) can be modeled. The tool can be coupled to the external reservoir simulation TOUGH2. Users are encouraged to build upon to the GEOPHIRES v2.0 framework to implement their own correlations and models.

geophires-v2's Issues

GUI and Sensitivity Analysis

Can we develop the code to allow for sensitivity analysis and potentially passing parameters as command-line arguments?

Help wanted: Splicing in a power plant

@NRELAdmin @kfbeckers @kmccabe1990 I am trying to see if it is possible to splice our custom ORC combined heat and power plant into GEOPHIRES. If I recall correctly, these ORC values are drawn from curve correlations, therefore the formulas at line 1783. Would it be possible to stick a power plant into this section? What happens to the power plant is we use a user-defined reservoir thermal drawdown curve? How is GEOPHIRES handling the reinjection temperatures from line 1813, for example, if the thermal drawdown curve is already defined?

I am looking for comments and variable definitions for etaull (lower limit of efficiency), etauul, etau, reinjtll, reinjtul, and reinjtemp. Basically, what do I need to give back to GEOPHIRES from our power plant to keep it from breaking the code? I have a heat fraction and an electricity quantity from a subcritical ORC, and the thermal drawdown curve should be defined by our external numerical model and imported via .csv. Thank you for any input you can offer.

etaull = C1*TenteringPP + C0
etauul = D1*TenteringPP + D0
etau = (1-Tfraction)*etaull + Tfraction*etauul


reinjtll = C1*TenteringPP + C0
reinjtul = D1*TenteringPP + D0
ReinjTemp = (1.-Tfraction)*reinjtll + Tfraction*reinjtul

Latest GEOPHIRES version?

Is this the latest official GEOPHIRES version? I've seen scattered references to a v3, dGeo, and -X so trying to figure out what's authoritative.
