  • Method and apparatus for determining the foaming characteristics of a crude oil stream at the wellhead
    Patent number: 4444044
    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.

  • Method and apparatus for determining the foaming characteristics of crude oil
    Patent number: 4426879
    Abstract: Measuring the foaming characteristics of crude oil comprises saturating the crude oil with a gas inert to the crude oil under high pressure and passing the gas-saturated oil into a flash separator. The amount of foam formed is measured with respect to the amount of gas withdrawn from the flash separator and the amount of oil contained therein.
