Beschreibung
Zusammenfassung:	The present invention relates to a method for determining the bubble point pressure of a fluid produced from a drilling well or circulating in an industrial installation. This method is characterised in that the transmission of light through the fluid is measured continuously, as the fluid flows in a well 1 which may or may not be equipped with a production column 3 or in a surface installation 5, 6, and the variation of the light transmission which results from the formation of the first gas bubbles in the fluid is determined as soon as the bubble point is reached following a reduction in the pressure of the fluid.
