Since water occurs naturally in petroleum formation, and is used in the secondary recovery of oil from wells, it is particularly desirable to be able to measure the water content of oil (watercut) during the exploration, drilling, production and transmission of oil and gas. In general, oil/water/gas cut measurements have been traditionally carried out by taking samples from wells or pipes, separating the oil, water and gas, and measuring the volumes of the separated components. As the water content of the oil flow is nonhomogeneous and changes over time in a pipe, there is no guarantee that a sample is representative. A new method for measuring the borehole watercut is given in this paper. It uses fiber-optic evanescent wave sensing (FOEWS) technology and nanotechnology based on the electrostatic self-assembly monolayer (ESAM) method. The watercut measured by this sensor ranges from 0% to 100% and its precision is lower than 2%. The characteristics of this sensor are analyzed.
