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 4-1/2″ IF BOX
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

I said about drilling formula software few weeks ago but my friend and I had limited time to write software. Therefore, we decide that we will give drilling formula in Excel spread sheet for FREE instead of software.
The advantages of Excel sheets over the general software are as follows:
• People can use it easily without any installation required and most of computers have MS Excel or Office program that can run the files. Moreover, some people may face the hassle because their company computes will not allow any installation.

Currently, we are trying to integrate useful drilling formulas from drillingformulas.com into the Excel file. And we expect that the drilling formula spread sheet will be launched on Monday, 28 March 2011. Everything is FREE and hopefully our file will help you and your work.
