Oil and Gas Wells in Southern Louisiana that Penetrated the Lower Miocene 1 Sequence

The drilling history documents oil and gas wells in the Lower Miocene 1 sequence as a whole and in 10-year intervals. The wells included in this interval are determined by completion date and by comparing the depth of the wells to structure contours of the Lower Miocene 1 sequence. The data are provided in a single file (lm1_prod.shp) as well as eight 10-year interval files covering 1920 through 1999.

These datasets contain basic data and interpretations developed and compiled by the U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. Other major sources of data include publicly available information from state agencies as well as publications of the U.S. Geological Survey and other scientific organizations. In cases where company proprietary data were used to produce various derivatives such as contour surfaces, the source is cited but the data are not displayed.

本钻井历史数据集整体记录了下中新统1层序（Lower Miocene 1 Sequence）内的油气井，并按10年时间间隔进行细分统计。该层序内纳入统计的油气井，需通过完井日期，以及将井深与下中新统1层序的构造等值线进行比对来确定。本数据集以单个形状文件（lm1_prod.shp），以及覆盖1920年至1999年的8个10年时间间隔子文件形式提供。

本数据集包含由美国地质调查局（U.S. Geological Survey）墨西哥湾沿岸框架研究与评估项目开发并汇编的基础数据与解译成果。其他主要数据来源包括各州政府机构公开的信息，以及美国地质调查局与其他科研机构的公开出版物。若在生成等值面等各类数据衍生成果时使用了企业专有数据，则会标注数据来源，但不会展示该专有数据本身。
