The purpose of this proposed research is to describe and interpret the origin of thinly bedded sandstones and mudstones formed in shallow-marine prodelta, shelf and offshore environments to develop quantitative analysis of the various formative processes. The novel research on developing improved depositional models for shales will help with ongoing exploration and acquisition evaluation by BP for unconventional opportunities in the Western Canada Sedimentary Basin. Our approach is innovative in that we measure mudstone sections at a centimeter-level of precision and in much greater detail than most previous studies, thus allowing us to characterize the processes of each event bed within a complete prodeltaic and shelf facies succession. We are seeking funding to examine in detail, the shales of the Mancos Formation, including the Juana Lopez Member. The data include outcrops that are extensively exposed in the deserts of the SW USA, and allow us to document vertical and lateral changes in these muddy facies at a level of detail not possible using subsurface data alone nor using outcrops in Canada, which are typically far less well exposed. Our proposed study provides an outcrop analog for prospective shale and halo plays important to BP Canada, including the Colorado-Alberto Group Shales in the Western Canada basin (Leckie et al., 1994) where lateral variability, connectivity, and reservoir characteristics are less well understood. We will also supplement our outcrop study with about 1000m of core data available from the New Mexico State Survey in Socorro that will allow us to investigate the chemostratigraphy. Our proposed work compliments BP assets, which include a large number of shallow marine, paralic, and fluvial reservoirs, such as the oil sands in Canada, and the paralic reservoirs in eastern Canada. The proposed research in these areas will be of continued value in better reservoir management of producing fields operated and owned by BP.

本研究的目的是描述和解释形成于浅海前三角洲、陆棚和近海环境中的薄层砂岩和泥岩的成因，以发展各种形成过程的定量分析。开发改进的页岩沉积模型的新研究将有助于BP在加拿大西部沉积盆地进行非常规勘探和收购评估。我们的方法是创新的，因为我们测量泥岩段在厘米级的精度和更详细的比以前的研究，从而使我们能够表征一个完整的前三角洲和陆棚相序列内的每个事件床的过程。我们正在寻求资金，以详细检查，页岩的曼科斯形成，包括胡安娜洛佩斯成员。这些数据包括在美国西南部沙漠中广泛暴露的露头，并使我们能够以单独使用地下数据或使用加拿大露头（通常暴露程度较低）不可能达到的详细程度记录这些泥质相的垂直和横向变化。 我们提出的研究提供了一个露头模拟的前景页岩和晕发挥重要的BP加拿大，包括科罗拉多州阿尔贝托组页岩在加拿大西部盆地（Leckie等人，1994），其中横向可变性、连通性和储层特征不太清楚。我们还将补充我们的露头研究与约1000米的核心数据，可从新墨西哥州国家调查索科罗，这将使我们能够调查化学地层。我们建议的工作补充了BP的资产，其中包括大量的浅海、浅海和河流储层，如加拿大的油砂和加拿大东部的浅海储层。这些领域的拟议研究将对BP运营和拥有的生产油田的更好油藏管理具有持续价值。
