Power Law mathematical model of Decline Curve Analysis is based on the following equation:
(1) | q(t)=q_{i} \exp \left( -D_{\infty}t- \left( t/\tau \right)^{n} \right) |
where
q_i = q(t=0) | Initial production rate of a well (or groups of wells) |
D_{\infty} | decline decrement at long times (the higher the D the stronger is decline) |
The cumulative production is then:
(2) | Q(t)=\int_0^t q(t) dt |
