Question

When using Vogel’s equation for a saturated reservoir, what is the exact percentage of the maximum potential flow rate achieved when the flowing bottom-hole pressure is zero?

Accepted Answer

When using Vogel’s equation for a saturated reservoir, the flowing bottom-hole pressure—which is the pressure at the bottom of the wellbore during production—is zero when the flow rate is exactly 100 percent of the maximum potential flow rate, also known as the Absolute Open Flow (AOF). Vogel’s equation is a mathematical model used to predict how much oil a well can produce as the bottom-hole pressure changes; it shows that as pressure decreases, the flow rate increases in a non-linear, curved fashion. Think of this like squeezing a tube of toothpaste: as you increase the pressure difference by squeezing harder, the flow increases, but eventually, you reach a physical limit where squeezing any more does not push out any more paste. In this model, zero bottom-hole pressure represents that theoretical limit where the pressure difference between the reservoir and the well is at its absolute maximum, allowing the well to reach its full potential capacity.
