bdahl...you are correct. The well will flow on its own if the reservoir pressure exceeds the theoretical hydraulic head.

Simply put, a well 1000 feet deep (producing horizon and source of the pressure) filled with water has a hydrostatic head pressure of 433 psi, and with any oil with a API gravity greater than 10 will create less head pressure (oil is lighter than water and therefore floats on top of water).

So it would appear that the well with 2000-2500 psi should flow very easily.

A pumping unit is required when the reservoir pressure is insuffient to overcome the pressure created by the column of fluid in the well.
