GIS Tool - ArcGIS
OLI Simulation Conference 2012
Integrating ArcGIS & CalcAQ • GIS Map will be developed as an interactive application
• Link will be setup between map and Excel
• Excel file will be hosted on the CEWC Web Server
• The Chemistry Tool will be setup on the CEWC Server
• Client will be able to access information through the map
• An Analyst will be able to update with the chemistry tool
OLI Simulation Conference 2012
Goals for the Chemistry Tool • Validate the Water Analysis
• Critically evaluate and recommend improvements in the Water Analysis
• Predict the properties of the produced water from the analysis
• Predict the results of transport, treatment, and disposal
OLI Simulation Conference 2012
Water Quality Analysis • Unavailable Water Quality Data
