  • Sensor assembly and system, and a method of determining the free water level in a hydrocarbon reservoir
    Patent number: 12366159
    Abstract: A sensor system and method for determining the vertical distance between a location (L) in a hydrocarbon reservoir (R) in a subterranean formation (F) and the free water level (FWL) in said reservoir. A sensor assembly (10; 10?; 10?; 10??) is configured for installation at a location (L) in a reservoir and comprises at least one sensor (11) in contact with or at least partly embedded in a porous material (13). At last a portion of the porous material comprises pores having hydrophilic surfaces, and the sensor is configured for measuring the water content in the porous material. Means are provided for determining the water saturation (SW) of the porous material and for estimating a pressure difference (PD) between the hydrocarbon pressure and the water pressure.
