Quick TD Estimator Calculator
How to use calculator
Granted it’s not the most complex operation but gives you a pretty good idea if you’re in a rush. Works for both feet & meters so make sure you scroll down, watch the video on how to save this guy & use when in a pinch.
Scroll back on your DDR (Data Drilling Recorder I think it’s called) Pason, Rig Watch, NOV what ever you’re using. Best is to take a good section of time say 6 – 9 hours. Enter in your start depth with an end depth. Not greater than your current depth. Keep it a nice even number for time, say 3 am to 9 am with that being a total of 6 hrs.
Enter in your current depth be it feet or meters & what your planned TD is. Be it which ever section of the well you are targeting. Could be days off for all we know..
If anybody asks what your normalized / Average ROP is you will have it. Add the time left to TD to your current time & you’ll be in the ball park for sure.
Keep in mind if something out of the ordinary happened during your Start & End depths this means you may have to adjust your window you were looking back on or say ROP drastically increases or slows down, adjustments can easily be made.
Hope you use it or like these calculators we are creating. Work safe & thank you for the support!
