Subsurface Mapping Software

The vendor required to provide subsurface geological maps software for various stakeholders including industry representatives, scientists, policymakers, educators, students, and citizens.
- System requirements:
1. Multiuser environment
•    Need to have at least 5 concurrent users
•    Need to have multiple users simultaneously work on the same project
•    Total of 5 geology licenses and 1 seismic license.
2. Cross sections
•    Create cross sections using geophysical logs. 
•    Must be able to include:
o    Scanned geophysical logs in TIF format
o    Geophysical logs in las format
•    Be able to incorporate both raster and digital logs on the same cross section line
•    Drawing options
o    Filled formations
o    Optional line style symbology
•    Tools
o    Be able to change from structure to stratigraphic drawing
o    Be able to change stratigraphic datums for stratigraphic drawing
o    Incorporate computed grids of formation tops in the cross section
o    Pick geologic formation tops and automatically populate the information back into the database
o    Create unassigned and generic correlations
o    Pay interval picking and calculations
o    Reference logs (aka slip logs)
3. Mapping
•    Base maps
o    Import and export Esri shapefiles and Esri file geodatabases
o    Consume GIS rest services for base maps
•    Contouring and gridding of geological surfaces and thicknesses
o    Gridding algorithms
1.    Kriging – both universal and ordinary kriging
2.    Minimum curvature
3.    Inverse distance weighting (IDW)
4.    Other types of splines
o    Contours should be editable
o    Contours and grids should be easily exported in standard GIS formats
•    Display and symbolize wells on the map based on database attributes
•    Bubble map production
•    Create scaled cross sections on the fly from the geological surfaces
•    Map deviated and horizontal wells (total vertical depth [TVD])
•    Created and display 3-dimensional maps and volumes
4. Analysis
•    Plot oil and gas production
•    Create decline curves of oil and gas production
•    Geophysical log cross plots—logs and zone items
o    Pickett cross plots
o    Hingle cross plots
o    Neutron-density cross plots
o    Neutron-sonic cross plots
o    Density-sonic lithology cross plots
o    matrix identification plot 
o    Matrix identification plot
o    Alpha mapping from the SP log
o    Clean sand or carbonate from the gr log
o    Rock typing and facies mapping
o    Create facies logs from cross plots
•    Log calculations—both standard defined equations, such as archie equation and the Vshale equation, along with user defined equations
5. Seismic interpretation (one module)
•    Import stacked and migrated seg-y data
•    Incorporate seismic line with mapped well locations—possibly change projection.
•    Create synthetic seismograms or incorporate synthetic seismograms from external sources
•    Time and depth conversions
•    Export CDP (values as text
6. database
•    Can be a proprietary database solution, but optionally have a SQL-based solution that can connect directly to a MS-SQL server database
•    Information to be stored in the database (non-exclusive examples of data stored in the database).
o    Well header data
o    Geologic formation tops
o    Direction drilled survey information
o    Core and sample information
o    Perforations
o    Produced oil, gas, and water volumes
o    Injected wastewater volumes
o    Zone items
o    las logs
o    TIF logs
•    Database should have the ability to be searchable and selectable
7. Data import and export
•    Import and export attribute data in a tabular format, such as csv, excel, MS-access tables
•    Import and export map data in GIS formats, such as Esri shape files, Esri file geodatabases, and Esri’s SDE geodatabases. 
•    Optional interface with Ersi’s ArcGIS pro.
•    Import and export projects and data in industry standard formats.
