Choose the remap option to read in these values. Enter this gap in the spreadsheet. Source numbers are user defined and could be set to any value. The following menu will appear. You will notice in the gather display that mute points have already been selected. If this step fails, you have an error in your spreadsheets somewhere. Select Stations for Receiver Index Method.

Velocity Uncertainty at Tzero and Tmax basically defines the bounds of your velocity fan. The following spreadsheet guide is designed to help you assign geometry to the line you are processing in the class. You may find that setting this display to four panels, and limiting the time range from 0 to 500 ms is useful. This will enable the screen swapping. In Disk Data Output, enter a name for a new output dataset. Build the following flow: Editing Flow: 1.

Scroll the spreadsheet to the right, and fill the Skid column with 27. Leave the Static column filled with zeros. A Disk Data Input step is required since it is not included within the macro. Enter the first and last live station numbers, select Yes to base source station numbers on receiver station numbers. This is where you specify the inline offsets that move the shots from integer station numbers to half station numbers. These next three chapters are examples of a difficult, an easy, and a most common approach to geometry assignment. From the main import menu, select Apply.

Select Sources from the main spreadsheet window. The information entered in these two columns depends on which method you chose for entering the pattern in the Patterns spreadsheet. The process applies linear moveout to shots and splices multiple shots together in a vertical fashion based on receiver surface station. From the main Land Geometry window, select Setup, and enter 90 for the Nominal Survey Azimuth. This immediately causes the fill window to display. The maximum frequency of the data is requested simply to internally resample the data to optimize screen resolution and execution time. However, if you create your own database attribute, a random number represents the database name and the description is what you typed in.

Finally you will view your new attribute in the database. The neural network works well with peaks and a gate length of 100 ms. Geometry Assignment Field Data 2. An improperly generated dataset or database may cause a subsequent exercise to fail. In this chapter we will cover the steps necessary to assign geometry to a line if some of the required information is present in the trace headers of the input dataset. Give your area a descriptive name that has meaning to you.

Drag your mouse to the end of the line to see the receiver range change. Pick first breaks on 20-30 traces. This display is often referred to as a Farr display. You should see the scroll icon remaining and you should be able to move your cursor into the data area. The Ordered Parameter Files database stores information in structured categories, known as Orders, representing unique sets of information applying to an individual line. Note The information contained in this document is subject to change without notice and should not be construed as a commitment by Landmark Graphics Corporation.

You will specify this half station difference using the skid column later. Choose the remap option to read in these values. In this chapter we examine the links between the database and the trace headers by determining first break linear moveout corrections. Technology for Teams is a service mark of Landmark Graphics Corporation. The transferred value can be loaded into an existing database attribute or trace header name, or you can create your own names. Make sure that you only have 20 rows in the Sources spreadsheet.

There will be no Primary or Secondary headers listed. Trace sample format: ----------------------------------------16 bit Skip primary disk Storage? The initial display includes a semblance plot, an isovel plot and a portion of the data stacked with the input velocity table. The second file is a fully interpolated velocity table based on the sparse picks you made on-screen. You can verify the source elevation was corrected by going back into the source spreadsheet. From the Area menu add a new area. The flow examples list key parameters for each process of the exercise.
