Select the seismic dataset, inline tracking or crossline tracking and select the tracking dataset. Adjust the parameter settings to your need:

  • Maxium trackings number 
    Sets the number of trackings displayed at the same time. 
  • Initial display time interval 
    Sets the time a set of trackings will be displayed before the next set is displayed. A low number will increase the speed of the scan and a high number will slow it down. 
  • Display order 
    Sets which direction the trackings should be displayed in.
  • Start tracking slice/End tracking slice 
    Sets the scan range. Default is the whole cube. 
  • Tracking interval 
    Sets the amount of trackings to load within the scan range. Default is set to the interval in your tracking dataset. By increasing this number you will reduce the amount of trackings loaded. 
  • Display type 
    Sets the color of the trackings. Decide on a single color by using Monochrome, use a different color for each tracking slice with Cyclic or color by amplitude by using Map

Start the scan by clicking the play button. You can pause or stop the scan anytime. Use the plus and minus buttons to increase and decrease the speed. You can also set the scan to loop, which makes it start over again when it has reached the end. To manually scan through the trackings click the pause button and use the arrows to go back and forth.

Parameter settings

  • Maximum surfaces number 
    The number of surfaces allowed to be displayed at one time. 
  • Initial display time interval 
    The time a surface will be displayed before the next one is displayed. A low number will increase the speed of the scan and a high number will slow it down. 
  • Display order 
    Surfaces can either be displayed from bottom of the cube to the top, or from the top of the cube and down. 
  • Starting time 
    The upper time constraint (z-value) in which to load surfaces. Default value is top of the cube, which in most cases would be 0. 
  • Ending time 
    The lower time constraint (z-value) in which to load surfaces. Default value is the bottom of the cube. 
  • Surface interval 
    The interval of surfaces to display. If set to 2, only half of the surfaces will be loaded. 
  • Size filter 
    The minimum size for a surface that are to be displayed. If set to 0, all surfaces are loaded. A normal value would be 1000, in order to avoid all the small surfaces. 
  • Display type 
    Surfaces can be mapped on time or attribute, or displayed in a single color. 

Enable contours by checking the Show contour box and adjusting the appropriate parameters.

...

When the surfaces have been loaded Geocap will start displaying them. You can see the amount of surfaces loaded at the bottom of the GIM surface scan menu.
If the number of loaded surfaces is:

  • Less than 500 
    Try reducing the size filter to 1000. You need to re-load the surfaces by clicking the stop button and then the play button again. 
  • 1000 
    It probably means that Geocap stopped loading surfaces before reaching the top of the cube because of the maximum surface number. Try to increase the size filter to 3000, or increase the maximum surface number if you want to load more than 1000surfaces. 

Surface interactive

Surface interactive lets you display surfaces by clicking on seismic reflectors in the graphical window. Go to Tools > GIM Data Visualization > Surface Interactive. Select Seismic Dataset and Surface Dataset.

...

Adjust the following parameters to your need:

  • Display Type 
    Map time or attribute, display in a single Monochrome color or display in different colors using Cyclic

  • Show Type 
    If set to Single the previous selected surface will be removed before displaying a new surface. Multi will keep displayed surfaces in the graphics window when displaying new surfaces. 

  • Color Table 
    Sets the color table used when mapping a surface. 

  • Maximum Offset 
    Sets the time interval above and below your pick where it will look for surfaces. 

To start displaying surfaces interactively click Begin and go to the graphics winodow. Display a surface by positioning the cursor on a reflector and clicking Y on the keyboard.
