The 2D & 3D Cross Plot Applet was created to assist the user in plotting Log ASCII Standard (LAS) Data and Measured Core Data in a standard 2D or 3D Plot. This Applets are an interactive web applications that allows the user to search, load, parse geological data from the user's PC or from the Kansas Geological Survey (KGS) database & file server. The user can display the following plots,

2D Cross Plot

3D Cross Plot
  • XY Plot User selects the curves from the data curves loaded.
  • Rhomaa-Tmaa Plot Apparent Matrix Density (Rhomaa) - Apparent Acoustic Transit Time (Tmaa) cross plot
  • MN PlotLitho-Porosity cross plot "M" and "N" from the Sonic-Density-Neutron logging data
  • Rhomaa-Umaa Plot Apparent Matrix Density (Rhomaa) - Apparent Photoelectric Factor (Umaa) cross plot
  • Rhomaa-NPHI Plot Apparent Matrix Density (Rhomaa) - Neutron Porosity (NPHI) cross plot
  • Porosity Difference Plot (Neutron Porosity-Density Porosity) vs Neutron Porosity (NPHI) cross plot
  • Th-K Plot Thorium - Potassium cross plot
  • Th-U Plot Thorium - Uranium cross plot
  • Th/K - Th/U Plot Spectral Gamma Ray Ratio cross plot
  • XYZ Plot User selects the curves from the data curves loaded.
  • Rhomaa-Tmaa-GR Plot Apparent Matrix Density (Rhomaa) - Apparent Acoustic Transit Time (Tmaa) - Gamma Ray (GR) cross plot
  • MN-GR PlotLitho-Porosity cross plot "M" and "N" from the Sonic-Density-Neutron logging data
  • Rhomaa-Umaa-GR Plot Apparent Matrix Density (Rhomaa) - Apparent Photoelectric Factor (Umaa) - Gamma Ray (GR) cross plot
  • Rhomaa-NPHI-GR Plot Apparent Matrix Density (Rhomaa) - Neutron Porosity (NPHI) - Gamma Ray (GR) cross plot
  • Porosity Difference Plot (Neutron Porosity-Density Porosity) vs Neutron Porosity (NPHI) - Gamma Ray (GR) cross plot
  • Th-K-U Plot Thorium - Potassium - Uranium cross plot
  • Th-U-K Plot Thorium - Uranium - Potassium cross plot
  • Th/K-Th/U-GR Plot Spectral Gamma Ray Ratio cross plot
The program allows the user to filter the data by depth range, Gamma Ray (API) Log Data, Thorium-Potassium Ratio Mineral data, Tops Data, Lithology/Texture Descriptions.

The web applications will take advantage of over 16 years of Java development experience at the Kansas Geological Survey (KGS) in developing web applications that plot oil & gas data and allows the geologist to perform analysis with that data, i.e. GEMINI Project & Tools on the KGS Web Site.

GEMINI (Geo-Engineering Modeling through INternet Informatics) Project was developed to allow the geologist to seamlessly integrate databases and geological analytical tools across the web. Analytical tools were designed for the independent oil and gas operators, consultants, and widely separated team members within and outside companies.

The web application was designed to create cross plots of LAS log data and measured core data that is loaded into the program. The program can retrieve multiple data types from different sources, but the program can only plot the data that is loaded in any one session. The program does not save the ASCII data, but will save the plots generated as Portable Network Graphics (PNG) files and Portable Document Format (PDF) files. This application can read Log ASCII Standard (LAS) version 3.0 Files developed by the Canadian Well Logging Society .
