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

The drilling history documents oil and gas wells in the Middle Miocene 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 Middle Miocene sequence. The data are provided in a single file (mm_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.

本钻井历史数据集完整记录了中中新统（Middle Miocene）层序内的全部油气井，并按十年时间间隔进行了分类统计。纳入该时间间隔的油气井，需通过完井日期，并将井深与中中新统层序的构造等值线进行比对这两种方式筛选确定。本次提供的数据包含一个主文件（mm_prod.shp），以及覆盖1920年至1999年的8个十年间隔子文件。

本数据集的基础数据与解译成果，均由美国地质调查局（U.S. Geological Survey）墨西哥湾沿岸项目框架研究与评估团队开发并汇编。其他主要数据来源包括各州政府机构公开的相关信息，以及美国地质调查局与其他科研机构发表的学术文献。若使用企业专有数据生成等值线面等各类衍生数据产品，仅会标注数据来源，不会公开具体的原始数据内容。
