Abstract
A method for determining the foaming characteristics of a crude oil stream at the wellhead comprising introducing the production crude oil stream from the wellhead into an elongated, horizontal separator under reduced pressure at a controlled flow rate, withdrawing evolved gas from the upper portion of the separator and measuring the flow rate thereof, withdrawing oil from the lower portion of the separator and measuring the flow rate thereof, controlling the pressure on the separator at a lower pressure than the wellhead pressure, controlling the liquid level of the oil in the separator, measuring the volume of oil in the separator, and measuring the volume of foam in the separator. The apparatus comprises an elongated horizontal separator, a crude oil inlet into one end of the separator, means for supplying a crude oil stream from the wellhead to the crude oil inlet in the separator at a controlled flow rate, means for controlling the pressure in the separator at a pressure lower than the wellhead pressure, means for withdrawing gas from the upper portion of the separator and measuring the flow rate thereof, means for withdrawing crude oil from the lower portion of the separator and measuring the flow rate thereof, means for controlling the liquid level crude oil in the separator, means for measuring the volume of foam formed in the separator, and means for measuring the volume of crude oil in the separator.
