Drilling Formulas Spread Sheet V1.7 is the latest version of Drilling Formula Spread Sheet. There are few new cement plug formulas and all formulas are unlocked so you can apply the formulas for your work. The formulas in this spreadsheet are as follows;
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
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 “Cross Over Generator”.
