FREE CROSSOVER GENERATOR EXCEL SPREADSHEET

FOR OILFIELD USE

You may have a problem regarding ordering the cross over to use on the rig because there

are so many threads used for the operation. For example if you have just only three threads

(3-1/2" IF, 4-1/2" IF, 7" BTC) for the operation. These are a total of 18 the possible

crossovers that you may need as listed below.

3-1/2 IF PIN X 7 BTC BOX

4-1/2 IF PIN X 3-1/2 IF BOX

4-1/2 IF PIN X 7 BTC BOX

7 BTC PIN X 3-1/2 IF BOX

7 BTC PIN X 4-1/2 IF BOX

3-1/2 IF PIN X 3-1/2 IF PIN

3-1/2 IF PIN X 4-1/2 IF PIN

3-1/2 IF PIN X 7 BTC PIN

4-1/2 IF PIN X 4-1/2 IF PIN

4-1/2 IF PIN X 7 BTC PIN

7 BTC PIN X 7 BTC PIN

3-1/2 IF BOX X 3-1/2 IF BOX

3-1/2 IF BOX X 4-1/2 IF BOX

3-1/2 IF BOX X 7 BTC BOX

4-1/2 IF BOX X 4-1/2 IF BOX

4-1/2 IF BOX X 7 BTC BOX

7 BTC BOX X 7 BTC BOX

You will get lost easily, won't you??

As you can see, it is quite tricky to determine all possible required cross over especially

when you have a lot of connections. Therefore we create an Excel file to help you do this

task. We call this file as "CrossOver Generator".

What will this file help you?

It will help you generate all possible x-overs then you can identify which one you need or

not. It will greatly reduce failure if you forget something.

Then you open the file using Microsoft Excel. You will see the screen link this.

Figure 3 - Main Page

You need to put the connection types in the blue cells only and you can input to 500

different connections (Figure 4 and Figure 5).

Figure 4 - Input Cells

Let's input some data into these cells.

4-1/2 IF (NC 50)

3-1/2 REG

4 XT39

Figure 5 - Input data

Then you click "Generate X-over" (Figure 6).

Figure 6 - Generate Result

Macro in the Excel file will generate all possible x-over like this (Figure 7).

Figure 7 - x-over list generated

The cross-overs which are generated by this macro consist of three main types which are

Box - Pin, Pin - Pin and Box - Box (Figure 8).

Figure 8 - Three main types of x-over

From the example above, you will get a total of 72 types of x-over.

Finally, you can select which one you need for operation from the list created by this file.

We wish this file would help you to figure out the possible cross over needed for your

operation.
