Synonym: Production Decrement = Production Decline Rate
| (1) | D(t) = - \frac{dq}{dQ} =-\frac{1}{q} \cdot \frac{dq}{dt} = - \frac{d (\ln q)}{dt} |
where
q(t) | Production rate at time t |
Q(t) | Cumulative production at time t |
In case of Exponential Production Decline the Production Decrement is constant in time:
D(t) = D = \rm const.
