One of several project memos supplementing the final report.
In order to determine properties of the thermal field at depth, the thermal conductivity stratigraphy of the basin must be known everywhere. In practice, it is infeasible to know the conductivity stratigraphy everywhere, so approximations are needed. For this project, the Correlation of Stratigraphic Units of North America (COSUNA) stratigraphic columns, available from the American Association of Petroleum Geologists were used as approximations of the stratigraphy because 1) well specific stratigraphy is not available for every well, and 2) the time constraints of Phase 1 would not be conducive to implementing specific geology to each well. COSUNA provides information on stratigraphy for 'sections' throughout the continent, including approximate thicknesses of different rock types. A weighted average of thermal conductivity for the entire wellbore can be approximated by consulting COSUNA charts for the various rock types and thicknesses encountered within the well. This memo documents the approach, assumptions, limitations, advantages, etc. of the COSUNA methodology for assignment of thermal conductivity and formation thicknesses to each well.
