Lab-scale core-flooding experiments are widely used as a standard experimental method to study and analyze physio-chemical properties of flowing phases through porous media. In the hydrocarbon extraction industry, core-flooding experiments are used to evaluate different enhanced oil recovery (EOR) strategies. As part of their evaluation, the accurate quantification of small quantities of produced oil at the effluent, is crucial for the correct interpretation of the experimental results. In this study, we present an innovative analytical method, which allows a fast, accurate and, non-destructive measurement for quantifying small quantities of oil in water (3–2500 μl) by implementing the advantages of a multi-wavelength separation analyzer. The presented method provides the user with a high sampling resolution and high precision during the experiment, allowing for the recording of continuous oil production curves.

实验室规模的岩心驱油实验被广泛用作研究和分析通过多孔介质的流动相的理化性质的标准实验方法。在碳氢化合物开采行业中，岩心驱油实验用于评估不同的提高采油率（EOR）策略。作为评估的一部分，对废水中少量采出油的准确定量对于正确解释实验结果至关重要。在这项研究中，我们提出了一种创新的分析方法，该方法通过实现多波长分离分析仪的优势，可以快速，准确且无损地测量水中的少量油（3-2500μl）。
