Development and Constraint of Physical Models for Geothermal Reservoirs The development of effective exploitation strategies requires scientifically sound characterization of geothermal reservoirs. Surface geophysical data are potentially the most powerful and cost effective means of exploration and characterization, providing images of the subsurface structures prior to extensive drilling.

Analysis Software Platforms

PSI (Pore Structure Inversion) [pdf] is a software platform that uses an integrated set of effective media models, combined with a maximum entropy inversion technique, to predict the pore structure of materials based on a flexible set of geophysical constraints. Applications include:

Lithological and petrophysical facies identification
Reservoir Characterization

FWB (Fracture WorkBench) [pdf] is an emerging software platform designed to support both inverse and forward modeling of the geophysical and flow properties of fracture networks. Geophysical constraints including permeability, electrical conductivity, and velocity and polarization of seismic waves can be used to predict the tensor properties of the resulting anisotropic medium. Applications include:

Prediction of velocity and permeability anisotropy from a given distribution of fractures
Inverting for possible fracture distributions given field observations of velocity anisotropy

Data Miner [pdf] is an interactive extensible software platform designed to aid in the processing and analysis of n-dimensional data such as data obtained from an AutoScan II laboratory system. Applications include:

Physically-based upscaling and modeling of physical properties
AVO analysis and modeling

ERL-SMP Finite Difference Modeling [pdf] NER has an in-house finite difference code developed in partnership with the Earth Resources Laboratory at MIT. The code models seismic waves in anisotropic, viscoelastic media, and models anisotropy with up to nine elastic constants. Applications include:

source mechanics
borehole wave propagation
the design and testing of downhole seismic tools and laboratory apparatus
the development and testing of reservoir delineation methods

FEHM (Finite Element Heat and Mass) is a finite element code developed by George Zyvoloski and co-workers at Los Alamos National Laboratory, and under license agreement to NER. The code is used to simulate flow and energy transport through porous materials and has undergone extensive validation and verification from the DOE. Applications include:

2-D and 3-D simulations of the flow of water/oil mixtures and air, and the transport of heat and contaminants in saturated- or partially-saturated heterogeneous porous media.
Investigations on reactive chemistry and transport pathways, via particle tracking and/or equivalent continuum methods.
Simulations of flow and transport in fractured media using equivalent continuum, discrete fracture, dual porosity or dual permeability approaches.
