Methane emission rate measurements from non-producing oil and gas wells in Canada

The dataset contains methane emission rate (mg/hr) measurements collected from non-producing wells between 2018 and 2023 across five Canadian provinces (Alberta, British Columbia, Ontario, Quebec, and Saskatchewan). All measurements were performed using the static chamber methodology, as described in the Supporting Information (SI-3) of the related publication. In Alberta and Saskatchewan, we measured the wellhead infrastructure and the surface casing vent separately (see column “Component”). We include the well attributes investigated in our study (i.e., type, status, operator, wellbore deviation, well depth (meters), age (years) and well density (wells/km2)). Refer to the Supporting Information (SI-1) of the related publication for more details on well attribute definition and classification.

本数据集涵盖2018年至2023年间，加拿大五个省份（阿尔伯塔省、不列颠哥伦比亚省、安大略省、魁北克省、萨斯喀彻温省）的非生产井甲烷排放速率（毫克/小时，mg/hr）测量数据。所有测量均采用静态箱法（static chamber methodology）完成，相关操作细节可参见对应发表文献的补充材料SI-3。在阿尔伯塔省与萨斯喀彻温省，我们分别对井口基础设施与地表套管排气口进行了测量，详见数据集中名为"Component（组分）"的列。本数据集纳入了本研究调研的井眼属性，具体包括井型、工况、运营方、井眼偏角、井深（米）、井龄（年）以及井密度（口/平方千米，wells/km²）。若需了解井眼属性的定义与分类细则，请参见对应发表文献的补充材料SI-1。
