HELP: Cross Section Build

The cross section requires the user to do their own memory management in building the cross section plot. For each cross section the user must decide how many wells/locations and thier respective depth ranges will fit in one plot. The memory size is dependant on the user's own PC.

The build applet allows the user to use a Profile Plot to select plot tracks, i.e. LAS curves, rock composition, colorlith plot track combinations and to set the depth range for each well/location that will appear on the plot.

The build applet creates the cross section project and is controlled from the cross section control XML file. The LAS 3.0 Files that holds each well/location data will be in the same directory as the control XML file.

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

1. Enter Title & Description of the Cross Section.
2. Select the "New" Button to create a Cross Section Control XML File.
3. Add each well/location to the cross section.
   • Select the "Add" Button to display the " Load well/location Data" Dialog.
   • Load well/location data from multiple sources,
     • PC - Log ASCII Standard (LAS) version 2.0 or 3.0 File.
     • PC - ASCII delimited Files
       • Formation Tops ASCII Comma Delimited File.
       • Measured Core Data ASCII Comma Delimited File.
       • Geologist Report ASCII Delimited File.
     • Kansas Geological Survey Well Data
       • Log ASCII Standard (LAS) version 2.0 File
       • Formation Tops
       • Measured Core Data
       • Perforations
     • Kansas Geological Survey Measured Sections Data
   • Select the "Load Data" menu option on the " Load well/location Data" Dialog to display the Profile Plot Module.
   • Select the Plot tracks for the well/location as you wish to see on the cross section plot.
   • Set the order of the plot tracks, left to right order, as you wish to see on the cross section plot.
   • Set Cross Section Depth Range (sets the amount of log data to save and reduces the total memory).
   • Select the "Save Data" menu option on the " Profile Control" Dialog to save the well/location Profile Data in the Profile Plot Module.
     • Unique Key created from Date & Time data for well/location, e.g. " W101020130432".
     • Well/Location Summary Header Information saved in Cross Section Control XML File. Cross Section Plot order saved in the order the well/location is created.
     • Well/Location Data stored in Log ASCII Standard (LAS) version 3.0 File, Unique key is used in LAS 3.0 Filename, e.g. "W101020130432.las".
4. Modify the order of wells/locations based on the latitude & longitude of the well location,
   • Use the Cross Section "Map" Button to view plotted locations.
   • Use the "Up" and " Down" Buttons to change order of each well/location.
   • Select the "Save Cross Section Information" menu option on the "Cross Section Build" Panel to save any well/location order changes to the Cross Section Control XML File, otherwise you will not see the changes.

Select a button from the following list to view Help pages.
Cross Section Build Panel
		Cross Section Build Panel Description
		Changing the Order of the Wells/Locations	This section will show how to change the order of the Wells/Locations in the "Cross Section Well/Location" List using the "Up" and "Down" Buttons to the right of the list.
		Save Cross Section Control Information	Any Changes to the Title or the Description you must Save the Data if you wish for the changes to be permanent. Also any change to the order of the wells will require you to save the data.
New Cross Section Project
		(1) New Control File	To start the build process you must first create a cross section control file and save it on your PC. This file will control how the cross section is displayed, i.e. the number of wells/locations, the plot tracks & order of the each well/location that will be displayed and the depth range. NOTE: Once you have finished this session you can move the cross section files anywhere on your PC later, but you must copy all the files that are associated with this cross section or it will not work correctly. The control file tells the cross section applets where the data is on your PC for this cross section.
		(2) Adding a Well/Location to a Cross Section
		(a) Load Data	Now add a Well/Location to the cross section. You must decide where the well/location data resides. The Load Well/Location Data Panel allows the user to select from multiple location and to combine that data into one plot, i.e. ASCII delimited files, Kansas Geological Survey Database & Server well data.
		(b) Profile Plot	The Load Well/Location Data Panel allows the user to select from multiple locations and to combine that data into one plot. Once the data is selected the user will select the File Menu Option and then select the "Load Data" menu option to open the Profile Plot. When the user saves the plot presentation in the profile module a unique key will be created for the well/location based on the Date & Time saved with a "W" prepended to the key. This key is also the base filename of the LAS 3.0, Well Base and Stratigraphic Units XML ASCII files generated. NOTE: Two other files created are not necessarily needed for the cross section project, Well Base ASCII Text File and a Stratigraphic Units XML File. Both files contain formation top picks, the Well Base ASCII Text File can be used with other Geological Software and the Stratigraphic Units XML File is used to push changes to top picks that the user would like to reflect in the archive version generated by the Profile Applet.
Existing Cross Section Project
		Open Control File	The cross section is created with a control.xml file and a number of Log ASCII Standard (LAS) version 3.0 Files depending on the number of wells/locations saved. This version only controls the naming convention of the wells/locations that are part of the cross section. The control.xml file holds the basic cross section plot information, The wells/locations information & order and the plot tracks selected for each well/location and the order of the tracks. The plot applet allows the user to save the "datum by" information and the depth range of the plot. Note: When you open an existing Cross Section Control File, the Build Applet will remember where the control XML file is and the name of the control XML File so when you save changes to the Cross Section it will automatically go to the directory where the cross section XML file originally was opened from to save changes, whether it is the XML File or any of the delimited ASCII Files, i.e. LAS 3.0 File, Well Base ASCII File and the Stratigraphic Units XML File.
		Modifying the Well/Location LAS 3.0 File Data
		(a) Load Data	If you wish to modify the data, i.e. increase the depth range, add or change the plot track presentation, that is presented on the cross section plot for a specific well/location you must select the "Modify" Button. You must decide where the well/location data resides. The Load Well/Location Data Panel allows the user to select from multiple location and to combine that data into one plot, i.e. ASCII delimited files, Kansas Geological Survey Database & Server well data.
		(b) Profile Plot	The Load Well/Location Data Panel allows the user to select from multiple locations and to combine that data into one plot. Once the data is selected the user will select the File Menu Option and then select the "Load Data" menu option to open the Profile Plot. When the user saves the plot presentation in the profile module the unique key that was originally created is used for the well/location. This key is also the base filename of the LAS 3.0, Well Base and Stratigraphic Units XML ASCII files generated.
		Editing Stratigraphic Units or the Pfeffer Flow Units
		Profile Plot Button	If the user only wants to modify the Stratigraphic Units or the Pfeffer Flow Units or Change the Plot Track Order highlight the well.location in the list and then select the "Profile" Button. When the user saves the plot presentation in the profile module the unique key that was originally created is used for the well/location. This key is also the base filename of the LAS 3.0, Well Base and Stratigraphic Units XML ASCII files generated.
