Queries for Permeability Conversion
In the conversion of data from 3SD to NASIS, the permeability values were
mistakenly converted as integers, so that fractional parts of the numbers were
lost. Mike Hansen in Montana developed a way to fix this problem in NASIS using
the Global Assign feature to put in the correct values for permeability.
As the first step in Global Assign, you will need to create a selected set
that contains all the horizon records that are supposed to have a certain value
of permeability. Then you fill in one correct value, and Global Assign will copy
it to all the other records. To help create the appropriate selected sets, Mike
developed the queries listed below. The bold face is the query name, and the
smaller print is the text of the query.
You can copy these queries into your NASIS database with a simple cut and
paste operation. Just follow these steps:
- Bring up NASIS, while this Web page is visible in another window.
- Select View from the menu, then Queries, and Query.
- Insert a new row, and fill in a query name.
- Zoom on the Query column to bring up the query editor.
- Come back to this page, and highlight the text for one query (use the
left mouse button and drag across the query you want to copy).
- Return to the query editor, and click, using the CENTER mouse button, in
the large Select Conditions box. This should place a copy of the query text
in the query editor.
- Apply this query, and repeat these steps for each query you want to
copy.
Hint: you can copy the query name in the same way. You have to insert the
new row and position the cursor on the Query Name column before
highlighting the text on the Web page.
