Detection of water in oil emulsions using spectral induced polarization

A method of emulsion detection, comprising:

• executing an oil production process from a volume of a formation:
• While
• executing the oil production process, obtaining real-time spectral induced polarization (SIP) measurements of the volume of the formation to determine a real-time real conductivity value (RCV) of a matrix material in the volume of the formation;
• determining an onset of water-in-oil (W/O) emulsion formation in the volume of the formation by analyzing the real-time RCV of the matrix material;
• and
• identifying the onset of the W/G emulsion formation when the real-time RCV first exceeds a first threshold value;
• obtaining the real-time SIP measurements of the volume of the formation using an SIP device that comprises:
• an SIP column including a plurality of potential electrodes arranged along a longitudinal direction of the SIP column;
• and
• two current electrodes positioned on opposing ends of the SIP column;
• Wherein
• an electrical current is injected into the formation through two current electrodes, propagating through the formation and encountering varying resistances;
• wherein
• these resistances influence the current flow, which is detected as potential changes by the potential electrodes.
