Brief

Production Potential is the maximum rate that can be delivered by Well, Pattern, Block or Reservoir.

Math and Physics

The Darcy's law can be written as:

 Q = T \times \Delta P \times J_D

where:

Q is the oil or gas production rate,
T is the Reservoir transmissibility and is given by the Mother Nature,
\Delta P is the Lift System Drawdawn which is set by the operational engineering practices[1],
J_D is the Completion System dimensionless productivity index which is set by the design engineering practices[1].

The rate Q is maximum then \Delta P and J_D are maximum.

Production Potential

Maximum \Delta P

The drawdown is:

\Delta P= \bar P_r - P_{wf}

The maximum drawdown is reached then the flowing bottomhole pressure, P_{wf} = 0, so:

{\Delta P}_{max}= P_r

Maximum J_D
