Abstract:
Systems and methods for identifying a likelihood of problematic reservoir fluid containing asphaltene and/or an asphaltene onset pressure (AOP) using downhole fluid analysis data are provided. A method may include retrieving downhole fluid analysis data corresponding to a reservoir fluid that was obtained by a downhole acquisition tool positioned in a wellbore. The method may also include using a statistical model trained using historical downhole fluid analysis data and laboratory measurements to identify, based on the downhole fluid analysis data corresponding to the reservoir fluid, a likelihood of whether the reservoir fluid contains asphaltenes or an asphaltene onset pressure (AOP) of the reservoir fluid.
