Here's some direct links to free apps and Excel files I have created.
The Google Drive link goes to a file containing handbooks, manuals, and resources from various companies. I did not create anything in there.
I don't guarantee anything here and use it at your own risk.
Enter your pump coefficient and tap the screen with your strokes to calculate pump rate.
Select tubing/casing size and depth to calculate volumes.
Calculate stretch/compression needed for setting tubing anchors and packers
A daily log for tracking pickup km's and expenses. Handy for tax time.
Tally up to 400 jts. You don't have to enter decimals (example 960 instead of 9.60), way faster.
Includes a wrap calculator, tool measurement sheet, printable sheets for you driller/derrickhand, and a sheet that calculates volumes from the cuts.
Lots of pipe data, BOP resources, packer, conversions, liner data, etc. I didn't make these.
