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:
where:
is the oil or gas production rate,
is the Reservoir transmissibility and is given by the Mother Nature,
is the Lift System Drawdawn which is set by the operational engineering practices[1],
is the Completion System dimensionless productivity index which is set by the design engineering practices[1].
The rate is maximum then and are maximum.
Maximum
The drawdown is:
The maximum drawdown is reached then the flowing bottomhole pressure, 
, so:
Maximum
The unstimulated vertical well potential in a pseudo steady radial flow is:
The maximum possible stimulated well potential for pseudo steady linear flow is:
, see 6/π stimulated well potential
The maximum possible stimulated well potential for steady state linear flow is:
, see 4/π stimulated well potential
Achieving potential
Can Production Potential be achieved?
The ideal, of producing and recovering at potential, is rarely obtained in practice. Reasons for this vary from company to company, but more often than not, the reason is Production Potential is not known and therefore not managed[1].
Calculating the Production Potential opens the pathway to achieve potential.
