How Advanced Sensors uses Microscopy for Measuring Oil and Solids Part 4: Calculating Concentration from Microscopy To determine the concentration of oil in produced water, we aggregate the volumes of all oil droplets detected in each image. This cumulative volume is then converted into concentration using a calibration curve. The same procedure is applied to solid particles. Because the depth of field is limited to 7 micrometers and the image area is relatively small (420 micrometers x 550 micrometers), each image captures only a fraction of the produced water. To ensure representative results, we analyze several hundred images using an averaging approach. Our unique averaging algorithm eliminates outliers and applies a weighted average technique, delivering highly accurate results even when particle count, parts per million (ppm), or concentration is low. This robust methodology allows us to provide reliable, precise measurements of oil and solid concentrations, enabling effective monitoring and control of produced water quality.

How Advanced Sensors uses Microscopy for Measuring Oil and Solids Part 3: Excluding Out-of-Focus Objects To ensure precise measurements and reliable analysis, our system excludes oil and solid particles that are not in focus. Out-of-focus particles can appear distorted in size, leading to inaccurate measurements. Our image processing algorithms evaluate the sharpness factor of each particle and include only those above a specific threshold. This guarantees that the measured particles provide accurate size values and enable precise parts-per-million (ppm) calculations. It’s important to note that the system operates within a narrow depth of field of just 7 micrometers—the range in which objects remain sharply in focus. By limiting measurements to this range, we ensure the analysis targets particles most relevant to the application. This focus enables accurate detection, measurement, and monitoring of produced water quality, providing actionable insights for effective control.

What is Fluorescence and How Does it Work? LIF and Ultra/Deep UV Fluorescence Not all oils are the same! Each oil has unique chemistry and a distinct ratio of aromatics to other hydrocarbons. The image illustrates the typical composition of crude oil, highlighting that only the aromatic components fluoresce. The types of aromatics in oil can also differ. For example, light oils have a higher proportion of mono-ring aromatics (MAHs) compared to the more complex polyaromatic hydrocarbons (PAHs). This means every oil has a unique fluorescence signature, and the fluorescence intensity correlates specifically to its measured content. This is why it’s crucial to establish individual calibrations for each oil type. Light oils, such as condensates, require excitation light in the deep UV spectrum, while crudes or heavy oils respond better to laser-induced fluorescence (LIF). Advanced Sensors provides cutting-edge solutions for both Deep UV Fluorescence and Laser-Induced Fluorescence oil-in-water analyzers. With our Deep UV capabilities, we dive into the excitation spectrum to include BTEX components as part of the measurement.

How Advanced Sensors uses Microscopy for Measuring Oil and Solids Part 2: Image Classification The process of image classification combines the power of Machine Learning with carefully crafted human-written algorithms. Using the human-written algorithms, we employ parameters such as aspect ratio, Hu Moments, number of turning points, roundness, projected circle, and other particle characteristics, these algorithms assess each object's shape to distinguish between oil droplets and solid particles. By mathematically evaluating these parameters, we determine whether a particle is oil or solid. The Machine Learning component then reinforces and validates the results, creating a robust and comprehensive classification system. This synergistic approach ensures accurate and reliable particle identification, supporting effective analysis and decision-making across various applications.

Laser Induced Fluorescence (LIF) is a well-established and widely used technique for measuring oil in water. Advanced Sensors has been leveraging this method since 2005 across diverse applications. Here’s how it works: high-energy laser light interacts with aromatic hydrocarbons in produced water, exciting the molecules. As they return to their normal state, they emit light, which is measured by a spectrometer. This emission, unique to each hydrocarbon, is converted into total oil concentration through a calibration curve—delivering accurate, reliable measurements for your needs.

How Advanced Sensors uses Microscopy for Measuring Oil and Solids Part 1: Optical Set-Up A high-resolution digital camera, paired with a 10x magnification lens, is precisely aligned at the glass interface of the process water. Simultaneously, a light probe illuminates the produced water, creating a vivid and detailed bright-field image. Inside the analyzer, a white LED transmits light through a fiber optic cable to the light probe, as illustrated in the diagram. In imaging mode, the system captures multiple images of the produced water, which are processed using the state-of-the-art Advanced Sensors Image Processing technology. This innovative process combines AI and machine learning with meticulously crafted algorithms developed by experts to deliver accurate and reliable analyses of oils and solid particles in the produced water. To the right, an original image of the produced water appears alongside a processed image, with blue highlighting oil and red indicating solids.
