Power Law mathematical model of Decline Curve Analysis is based on the following equation:
|
|
where
q_0 = q(t=0) | Initial production rate of a well (or groups of wells) |
D_0 | initial production decline rate |
\displaystyle D(t) =- \frac{dq}{dQ} | production decline rate |
\displaystyle Q(t)=\int_0^t q(t) dt | cumulative production |
Alternative form
The original form was:
|
where
D_{\infty} | decline decrement at long times (the higher the D the stronger is decline) |
