sorry about that, I thought I attached it.
jghirst your example helped me out a lot though, gives me a better idea of what to do. What do you think I could do in the case that the time intervals are not constant between subsequent pressure and flow measurements...
Thank you for the reply. I have graphed already graphed it and even though it does help identify regions of constant pressure, however, I don't want to go through the spreadsheet manually to find this as it is very time consuming but just have a function that can do it for me.
I am having some trouble identifying the function or the method that I need to use to go about my issue.
I have exported a bunch of data into excel showing the data & time, pressure and flowrate. What I want to do is be able to identify atleast one hour periods of time that have a relatively...
I have step rate data from a salt water disposal well and I have plotted a graph showing the bottomhole pressure versus the [injection] flow rate which helps me find the formation frac pressure. I want to be able to do use the same plot and add some more graph lines corresponding to lower...
