3D Crossplot Description

Work is partially supported by the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) under Grant Number DE-FE0002056.

The 3D Cross Plot Applet was created to assist the user in plotting Log ASCII Standard (LAS) Data and Measured Core Data in a standard 3D Plot. This Applet is an interactive web application 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,

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 9 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 .
