nSights provides numeric well-test analysis with integrated uncertainty assessment and inverse modelling.
nSights provides state-of-the-art well-test capabilities for analyzing hydraulic and gas tests conducted in complex test environments. nSights features and capabilities include:
 

• Multiple conceptual models
  -Dual porosity, leakage (from above and/or below), well-bore skin (enhancement or damage)
  -Flow dimension capability allows for interpretation/analysis of non-radial flow such as fracture systems
   
• Numeric simulator
  -Compensates for non-ideal test procedures such as pumping rate changes
  -Allows incorporation of long-term pre-test pressure histories
  -Supports combinations of conceptual models not supported by analytic techniques (e.g. dual porosity aquifer with leakage)
   
• Advanced graphical analysis techniques
  - Derivative plots, decline plots, pulse/slug and flow dimension analysis
  -Advanced derivative calculation for noisy field data
  -Time and space superposition
   
• Optimization (inverse modelling)
  - Automatic fitting of field data with Levenberg-Marquadt and Simplex methods
  -Multiple constraints (e.g fit derivative & cartesian results, fit results from multiple observation wells simultaneously)
  -Advanced statistical processing for confidence region estimation
  -Can incorporate Latin Hyper-Cube or Monte-Carlo sampling of uncertain parameters to determine range/distribution of possible hydraulic parameters
   
• Data pre-/post-processing
  -Extensive facilities for importing, cleaning and processing field data
  -Report quality 2D and 3D plotting 

paCalc is a modelling framework and library of integrated sub-models to estimate risk and contaminant mass flux.

Geofirma also offers services to create application-specific analysis and visualization software. Our C++ framework of graphics and data processing objects can be used as a basis for proprietary software in Windows and Linux.

paCalc is a modelling framework that estimates risk and contaminant mass flux associated with contaminated sites or waste disposal facilities. paCalc consists of a sampling facility and a library of integrated sub-models, including: source terms, unsaturated zone and saturated zone flow and transport, and human risk/dose calculation. Sub-models are linked into a network pathway model defined by the user. Stochastic distributions are defined for uncertain variables. Multiple realizations of the network are executed and calculated output post-processed.

paCalc was originally developed by Geofirma staff for use on the Yucca Mountain program. Geofirma has expanded paCalc capabilities to address concerns associated with chemical contaminants and increased it's applicability for the assessment of contaminated sites and hazardous/chemical disposal facilities.

paCalc is licensed software available from Geofirma. We provide sales, support and training for paCalc.
