摘要
The invention relates to a method and an apparatus for determining a minimum miscibility pressure of a fluid with an oil composition. The method comprises the steps of: placing a fluid into a pressure chamber (14) at a first pressure; the pressure chamber (14) comprising at least one capillary tube (32) having one end disposed in the oil (36), measuring the height of the oil in the capillary tube, repeating the measuring for at least a second pressure and determining the minimum miscibility pressure of the oil with the fluid by extrapolating from the two or more measurements.
