National Geologic Carbon Dioxide (CO2) Sequestration Assessment Project: Bighorn Basin (C5034) Well Density

Drilling-density cell maps show the number of wells that have been drilled into the storage assessment unit (SAU). Each 1-square-mile cell has a count for the number of unique well boreholes drilled into the SAU. For a given sedimentary basin, the USGS National Geologic CO2 Sequestration Assessment Project identifies SAUs containing the potential for storage and sequestration of carbon dioxide. Proprietary well header data from IHS ENERDEQ through 2010 were queried to determine which wells were drilled into specific SAUs. The coordinates of wells are proprietary and cannot be released; however, counts of the number of wells per square mile are presented in the well drilling density data layer.

钻井密度格网地图展示了钻入储层评价单元（storage assessment unit，SAU）的钻井总数。每块1平方英里的格网均会统计钻入该储层评价单元的唯一钻井眼数量。针对特定沉积盆地，美国地质调查局（USGS）国家地质二氧化碳封存评价项目将甄别出具备二氧化碳储存与封存潜力的储层评价单元。本研究通过查询截至2010年的IHS ENERDEQ专有钻井表头数据，确定了钻入各特定储层评价单元的钻井信息。钻井坐标属于专有信息，不予公开；但每平方英里的钻井数量统计已收录于钻井密度数据图层中。
