The database used in the assessment will include all available well logs, cores, tests seismic, and aeromag data. The study area contains 684 wells (Figure 1) of which 225 are cored for a total length of approximately 9300 meters. At least 360 wells possess DST information, with a total of 1092 DSTs conducted,the majority of which evaluated Devonian carbonates. In addition, 8,595 kilometers of scanned, public seismic data and 200 m X 200 m residual total field aeromag data are also available.
The following tasks will be performed:
1. All cores will be examined and digitally photographed, with a representative set logged in detail;
2. The library of thin sections stored at G.S.C. Calgary will be accessed for selected samples that will be described and photographed using standard petrographic techniques;
3. Additional thin section samples will be collected and prepared, as needed, from selected wells;
4. Core descriptions and a regional grid of cross-sections will be used to generate a revised stratigraphic tops database for all available well logs. A suite of isopach, structure, and porosity maps of economically important units will be constructed.
5. Where well control is not sufficient, cross-sectional displays will be created using surface geologic maps and topographic maps for elevation control.
6. Publicly available seismic data will be interpreted on the basis of key structural and stratigraphic features and a suite of maps, based on seismic interpretation, will be created;
7. In areas where public seismic coverage is unavailable, an attempt will be made to use available gravity and magnetic data to define basin geometry and identify structural trends;
8. Publicly available geochemical data will be compiled from well files and published reports. New analyses will be gathered, as determined by sample availability and the need for additional data coverage. Wells with geochemical data will be analyzed for quality and maturity of potential source rocks. A suite of 1D basin models will be constructed from this data, using BasinMod, to estimate timing of hydrocarbon generation and expulsion;
9. All well tests will be evaluated on the basis of reliability, pressures, and the composition of recovered fluids. From this data, a suite of pressure-elevation graphs, potentiometric surface, water/gas chemistry and pool delineation maps will be constructed. Potential damaged tests/bypassed orrportunities will also be identified
10. Pool studies integrating mapping, seismic interpretation, hydrodynamics and reservoir description will be completed for the Pointed Mountain, Kotaneelee, Beaver River, Liard, Cameron Hills and Maxhamish fields.
