Arp's Power Law mathematical model of Decline Curve Analysis is based on the following equation:

|
q(t)=q_{i} \cdotexp \left( 1+b \cdot D \cdot t-D_{\infty}t- \left( t/\tau \right)^{-1/b}n} \right) |
where
| Initial production rate of a well (or groups of wells) |

body | D=-\frac{1}{q}\frac{dq}{dt}_{\infty} |

decline decrement at long times (the higher the the stringer stronger is decline) |
| defines the type of decline (see below) |
The cumulative production is then:

Q(t)=\int_0^t q(t) dt |
