圣玛丽教区土地公司成立于 115 多年前，当时总部位于明尼苏达州，最初收购的是其同名南路易斯安那教区的土地，着眼于发展养牛业。

但这并没有取得很好的结果。幸运的是，石油和天然气取得了成功。虽然 SM Energy 的名称被缩短，并且不再专注于路易斯安那州，但 E&P 正在开拓米德兰盆地的扩张，引领南德克萨斯州的 Austin Chalk 增长，并在犹他州新兴的 Uinta 盆地迅速发展。

SM 公司依靠数据密集型的野猫勘探方法，通过不同的层位将米德兰盆地向南和向北扩展，并随着 Eagle Ford 页岩的成熟，延续了其在白垩层中的成功。

Founded more than 115 years ago, then-Minnesota-based St. Mary Parish Land Co. started out buying up acreage in its namesake southern Louisiana parish with an eye toward the cattle business.

That didn’t work out so well. Fortunately, oil and gas did. While SM Energy has a truncated name and no longer focuses on Louisiana, the E&P is pioneering expansions of the Midland Basin, leading Austin Chalk growth in South Texas and growing rapidly in the emerging Uinta Basin in Utah.

SM’s data-heavy wildcatting approach has helped expand the Midland Basin both to the north and south through different benches, and extend its success in the Chalk as the Eagle Ford Shale matured.
