HELP: Gamma Ray Colorlith Cross Section

The cross section requires the user to do their own memory management in building the gamma ray colorlith cross section plot. The web app will allow up to 50 wells in building the gamma ray colorlith cross section. The memory size is dependant on the user's own PC.

NOTE:This web app requires Log ASCII Standard (LAS) File as input and there must be a Gamma Ray Log Curve in the file. Although the web app reads all the data in the LAS File it will only use the Well Header Information and the Depth & Gamma Ray Log curves. If the LAS file is a version 3.0 then the tops will also be included.

There are a number of steps in building a cross section:

• Quick Gamma Ray Colorlith Cross Section Work Flow.
  1. Select the "New Well" Button to load data for each well into the cross section.
     • Maximum of 50 wells allowed for plotting a cross section.
     • Minimum of 1 well can be plotted in the cross section plot.
     • For Each Well loaded
       • Verify that the well has a Latitude, Longitude and Elevation.
       • If any Latitude, Longitude and Elevation is missing then
         • Select the "Modify" Button to enter the missing data, either manually or by using the "Search KGS Database for Well Header Information" Button to search the Kansas Geological Survey (KGS) database for existing well header information.
  2. For more than 2 wells select the "Map" Button to verify the order is correct.
     • If a well is out of order then
       • Highlight the well in question.
       • Select the "Up" or "Down" Buttons to change the order of the well, verify with Map Image Dialog
  3. Select the "Cross Section" Button.

Select a button from the following list to view Help pages.
	Cross Section Panel Description
	Buttons
		New Well	Import Wells data to the Cross Section. This button opens a dialog that allows the user to load multiple data types from multiple sources, i.e. the ASCII Delimited Data Files on your PC and the Kansas Geological Survey (KGS) Database & File Server. As the ASCII files are read in, the filenames are inserted into the text fields to give the user a positive feed back.
	*	Remove	This button allows the user to highlight a well and remove it from the well list along with their imported data.
	*	Remove All	This button allows the user to remove all of the wells from the well list along with their imported data.
		Modify	This button allows the user to modify the well header information for the displayed well/measured section, specifically the Latitude, Longitude, Elevation and Well Status, which allows the well to be plotted on the Well Map Image. All well header information can be changed, but the XYZ location of the well is important.
		Up and Down	This section will show how to change the order of the Wells in the "Cross Section Well" List using the "Up" and "Down" Buttons to the right of the list.
	Plot Buttons
		Map	This button allows the user to plot the selected wells on a latitude/longitude grid.
		Cross Section	This button will create a cross section with the well/measured section data downloaded in the order presented in the well list table.

		PNG of Map Image	Create a Portable Network Graphics (PNG) Image of Cross Section Map. This process creates the PNG Image and launches a web page with a link that allows the user to launch the Portable Document Format (PDF) Applet that will create a PDF Document of Cross Section Map.
	Cross Section Plot Control Description
	Global Cross Section Plot Actions
		Change Depth Scale	Change the Depth Scale of the Cross Section Plot, which allows the user to expand a section to view in more detail.
		Change Depth Range	Change the Depth Range of the Cross Seciton Plot to filter the depth information.
