Oil & Gas - Unconventional Well Locations

The following data set contains all the Oil & Gas Wells in Pennsylvania that the Dept of Environmental Protection has locational information on. The wells are broken into two formation types of conventional and unconventional wells. A conventional well is a bore hole drilled or being drilled for the purpose of or to be used for the production of oil or natural gas from only conventional formation(s). A conventional formation is any formation that does not meet the statutory definition of an unconventional formation. An unconventional gas well is a bore hole drilled or being drilled for the purpose of or to be used for the production of natural gas from an unconventional formation. Unconventional formation is a geological shale formation existing below the base of the Elk Sandstone or its geologic equivalent stratigraphic interval where natural gas generally cannot be produced at economic flow rates or in economic volumes except by vertical or horizontal well bores stimulated by hydraulic fracture treatments or by using multilateral well bores or other techniques to expose more of the formation to the well bore.本数据集涵盖宾夕法尼亚州境内所有由宾夕法尼亚州环境保护部掌握位置信息的油气井。本数据集将所有油气井按地层类型划分为常规井（conventional well）与非常规井（unconventional well）两大类。常规井指仅从常规地层（conventional formation）中开采石油或天然气的已钻或待钻井眼；常规地层指不符合非常规地层（unconventional formation）法定定义的所有地层。非常规天然气井（unconventional gas well）指为从非常规地层中开采天然气而钻成或待钻的井眼。非常规地层指赋存于埃尔克砂岩基底或其地质等效地层间隔之下的页岩地质地层，此类地层中的天然气通常无法以经济产率或经济产量进行开采，除非采用经水力压裂作业（hydraulic fracture treatment）改造的垂直或水平井眼，或使用多分支井眼及其他技术以提升井筒与地层的接触面积。
