摘要
In a method for controlling the interface level between a liquid inventory and an overlying steam chamber in a subterranean petroleum-bearing formation, an inflow relationship is developed to predict the vertical position in a gravity field of the interface between two fluids with a density contrast (most commonly a water/oil emulsion and steam), relative to a horizontal producer well. The inflow relationship is applied to producer well completions by designing the completion to raise or lower sand face pressures over the horizontal length of the well. This pressure distribution will affect liquid levels according to the inflow relationship. Axial flow relationships for the liquid inventory may be developed to facilitate estimation of liquid levels at selected locations. Axial flow relationships for the steam chamber may also be developed to estimate the effect of the injector well completion on the steam chamber pressure and, in turn, the liquid level.
