Well testing_Horner Plot vs Derivatives?

The difference you got is inevitable, however, it should be within acceptable range. You got to judge that yourself. The results from the semi-log, Cartesian plots depends on where every flow period, e.g ETR(C), MTR(K,s), LTR(boundary) begins and ends and that up to the engineer. This results are then taken as an input for the match so we can validate the models used to describe every period.

Thank you for your explanation.
