The image represents the total production time. To calculate the total production time, two essential parameters are needed, and these parameters are Cumulative Production before Shut-In (Np) and Stabilized Well Flow (Qo).
The formula for calculating the total production time:
tp = 24Np / Qo
Where:
tp = Total Production Time
Np = Cumulative Production before Shut-In
Qo = Stabilized Well Flow
Let’s solve an example;
Find the total production time when the cumulative production before Shut-In is 24 and the stabilized well flow is 43.
This implies that;
Np = Cumulative Production before Shut-In = 24
Qo = Stabilized Well Flow = 43
tp = 24Np / Qo
That is, tp = 24 x 24 / 43
tp = 576 / 43
tp = 13.39
Therefore, the total production time is 13.39 hrs.
