“…Add up the large amount of downhole pressure data, the traditional manual classification of flow process is more time-consuming and laborious. Therefore, the smart well technology is becoming an important methodology to study the downhole well-testing data processing and the data interpretation [2]. Many published papers described the methods of processing and interpreting pressure data.…”

During petroleum exploration and exploitation, the oil well-testing data collected by pressure gauges are used for monitoring the well condition and recording the reservoir performance. However, due to the large number of the collected data, the classification of this large volume of data requires a previous processing for the removal of noise and outliers. It is impractical to partition and process these data manually. Vibration-based features reflect geological properties and offer a promising option to fulfil such requirements. Based on the 75 on-site measured samples, the time-frequency-domain features are extracted and the classification performance of three classical classifiers are investigated. Then the downhole data processing and classification method is present by analysing the cross interaction of different types of data features and different classification mechanism. Several feature combinations are tested to establish a processing flow that can efficiently remove the noise and preserve the shape of curves, high signal to noise ratio rates, with minimum absolute errors. The results show that optimal multi-feature combination can achieve the highest working stage identification rate of 72%, the parameters optimized support vector machine can achieve the better classification performance than other listed classifiers. This paper provides a theoretical study for the data denoising and processing to enhance the working stage classification accuracy.

This technical paper delves into the Application of Smart Well Technology in Polymer Flooding for Heavy Oil Recovery, with a focus on optimizing injection operations for Enhanced Oil Recovery (EOR) in challenging reservoir conditions. The study involves a comprehensive analysis of reservoir properties, feasibility considerations, and cost-benefit assessments related to the integration of smart well technology. By incorporating real-time monitoring and control systems, smart wells autonomously optimize injection operations to maximize oil recovery while minimizing polymer consumption. The research encompasses a thorough analysis of polymer flooding, heavy oil recovery methods, and smart well technology, culminating in the development of a simulation model to evaluate the performance of smart well-assisted polymer flooding. Results and discussions from the simulation of polymer injection and production plans highlight the potential benefits and challenges of incorporating smart well. technology in polymer flooding operations. This study contributes to the advancement of enhanced oil recovery endeavors and provides valuable insights for future research and development in the field of heavy oil recovery.
