A project in Geocap can be generated generic; i.e. along its development. It is however nice to have an initial setup. The project in this text is just called Wells and logs and referred to as the project. Here is the initial setup for the project with wells and seismic lines.

The contents inside the folders will gradually be generated along its use. The example shows what this test project may look like.

Working with the project manager and setting up a project is explained in project manager introduction Geocap Projects.

Info
titleQuick explanation of the folders in the peoject:
  • Images. A folder to contain screenshots from the screen. Just a nice thing to have in order to save an informative display. The screenshots are taken by data->Screenshots
  • Seismic lines. A folder to contain 2D seismic lines that are present in the wells area. A seismic line is read by Seismic lines->Import->SEGY-2D
  • Well log images. A folder to contain well log images from some paper reports that are saved as images in a picture format (jpeg, png, bmp, etc ) and read into the project. They can be calibrated and displayed in the 3D scene attached to its well.
    A well log image is read by Well log images->Import->Generic. Browse in the images and use Automatic reading.
  • Well tops. A folder to contain well tops. In this case the well tops are taken from NPD's facta pages.
  • Wells. A folder to contain wells with all the logs. The wells are usually in LAS format and read into the folder with the LAS reader that is found under Wells->Import->LAS

    Ribbon log display X dir
    
    Ribbon log display Y dir
    
    Tube log display 
    
    

These display options are used when we want to see the well logs in tube or ribbon mode, see image below.

  • Log display direct mode
    Code Block
    bgColor#ffffaa

    Log Display black
    
    Log Display blue 180 
    
    Log Display green 
    
    Log Display pink 180 
    
    Log Display red 
    
    Log Display yellow 180 
    
    

These display options are used when we want a quick visualization of the well logs. The name tells which color it is using and the number which direction. All the settings are up to the user to change in a real project. The changing is done in edit mode of the command object. One can copy and paste a command object and rename it according to the settings.

  • Log display interactive mode
    Code Block
    bgColor#ffffaa
    borderWidth1
    borderStylesolid
     
    Log Display interactive1
    
    Log Display interactive2 
    
    

These display options are used when it is necessary to work interactively with the log display. The interactive mode is achieved by setting Execution mode to Interactive.

Work interactively and set the parameters for optimum display. . Copy and paste and rename a proper command object according to the settings.

In general this application is tuned for displaying seismic in the background. Below is some examples of well log displays and a 2D seismic section running across that well:

    Seismic Display
    
    Seismic Display LOD 
    
    

Seismic display are provided with to options:

  1. Standard seismic display. It may be too smoothed to get all the details.
  2. Level of detail (LOD) seismic display. A rendering technique that has different resolution according to view distance. Recommended and should be used if the graphical card supports it.
  • Text
    Code Block

    Text at cursor position
    
    

Edit the command object and write in the preferred text. Then place the cursor at any position. In 2D mode this is done by just right click in the screen. Then press Execute.

  • Code Block

    Well text at lower left
    
    

Highlight a well and Execute the command object. The text is placed at the lower left of the screen.

  • Well display options
    Out of the command objects in this folder one option will be emphasized.
  • Code Block
    bgColor#ffffaa
    borderWidth1
    borderStylesolid
    
    Display well and scale
    
    

Highlight a well. Then Execute the command object. It scales the well to the middle of the screen and display a red line looked upright. Especially the scaling is important so that the well will be in focus. It is equivalent to well->Zoom to Data.

To display the well in a thicker line, execute Display well linewidth 3.

  • Well log image display
    Code Block
    bgColor#ffffaa
    borderWidth1
    borderStylesolid
     
    Well log image calibration
    
    

This is a command object for calibrating and display of a well log report taken from a paper. The image is read into a Generic folder. Then it is calibrated to be displayed along the well.

Read more about this in Calibration and display of well log images.

The Operation mode entry Calibration shall be checked in in order to see the command object Well log image calibration.

  • Z annotation
    Out of the command objects in this folder one option will be emphasized.
    Code Block
    bgColor#ffffaa
    borderWidth1
    borderStylesolid
    
    Z annotate 100
    
    

Highlight a well. Then Execute the command object. The well line is annotated for each 100 meter. Just a quick way to display the height along the well string. The other command objects have similar functionality.

Well annotation is also found in the Log Display menu.
