数据集介绍

构建方式

The Alberta Wells Dataset was meticulously constructed by leveraging medium-resolution multi-spectral satellite imagery from Planet Labs, in conjunction with comprehensive well location data sourced from the Alberta Energy Regulator. This dataset encompasses over 213,000 wells, categorized into abandoned, suspended, and active states, all verified by domain experts. The data collection process involved rigorous quality control, including the removal of duplicate entries and the categorization of wells based on expert-defined criteria. The geographical bounds of the wells were calculated, and the region was divided into non-overlapping square image patches, each covering an area of 1.1025 sq km, ensuring a balanced distribution of well and non-well patches.

使用方法

The Alberta Wells Dataset is designed for training and evaluating machine learning models aimed at detecting and pinpointing oil and gas wells from satellite imagery. Researchers and practitioners can utilize the dataset for tasks such as binary segmentation and object detection, leveraging the provided annotations to develop and fine-tune algorithms. The dataset's structure, including its training, validation, and testing splits, allows for robust model evaluation. Additionally, the dataset's geographical diversity and balanced distribution of well and non-well patches provide a realistic simulation of real-world conditions, enhancing the models' generalization capabilities.

背景与挑战

背景概述

阿尔伯塔油井数据集（Alberta Wells Dataset）由魁北克人工智能研究所（Mila）和麦吉尔大学的研究人员于2024年创建，旨在通过卫星图像大规模定位废弃、暂停和活跃的油气井。该数据集包含了来自阿尔伯塔省的超过213,000个油井的详细信息，这些信息由阿尔伯塔能源监管局（Alberta Energy Regulator）提供，并经过领域专家的验证。这一数据集的创建填补了现有数据集在识别废弃或暂停油井方面的空白，为环境监测和气候变化缓解提供了重要的工具。
