Easily accessible and accurate data on unconventional hydrocarbon systems is essential to both the industry and academia to enhance the understanding of parameters controlling the geology of these challenging plays and at the end maximize exploration success.

In order to simplify such comparison studies the EUR-SG-RC (Energy from Unconventional Resources Support Group and Research Center), an initiative between U.S. and Polish research institutions, are compiling a unified and comprehensive relational database containing data and information about a wide variety of geologic, geophysical, geomechanical, petrophysical, and paleontological proxies.

Initial focus on populating this database will be given to a series of prolific plays in the U.S., foremost the Bakken/ Three Forks oil shale play and associated emerging plays in Montana, and the Silurian Graptolitic Shales in Poland. Future efforts will expand this database to other regions and other stratigraphic intervals. All data will be derived from original research conducted by members of the EUR-SG-RC as well as publicly available data.

The ultimate goal of this database is to provide constrains on a variety of geologic topics and scales important to shale gas and oil shale plays, ranging from basin models to detailed stochastic, object based and pixel-oriented reservoir models.

For Quality Control purposes and consistency all obtained data from original research and publicly available sources are evaluated independently in at least two participating research institutions, then combined, quantified and organized in the source-database. The goal of this structured quality control process is to create a database of unconventional oil and gas plays based on well-defined and consistent evaluation criteria.

In this presentation we will demosntrate a workflow in using this data in a series of case studies from the Bakken Formation in Montana and the Silurian in Poland. There we utilized a range of geophysical, sedimentological, and biogenic data to define the basin and reservoir architectures within a detailed biostratigraphic framework, as well as included selected petrophysical properties (textures and microstructures, geometry of pores, TOC, and mineralogy) to evaluate the reservoir quality of these rocks.
