Integrating Fluid Inclusion Stratigraphy
Fluid Inclusion Technologies
and Continental Laboratories are conducting a regional evaluation of petroleum charge, H2S trends, seal and reservoir quality assessment from deep Devonian Formations within the Alberta portion of the Western Canada Sedimentary Basin. The foundation for this study is fluid inclusion volatile analysis (Fluid Inclusion Stratigraphy or FIS) of over 10,000 rock samples from 35 key wells, representing most of the current exploration fairways. Detailed fluid inclusion petrography, geochemistry and rock description will follow on potential reservoir sections that show significant FIS anomalies (possible migration pathways, paleo-hydrocarbon columns or present-day hydrocarbon columns). Use of these data will lead to better assessment of trap delineation, reservoir compartmentalization, reservoir quality, seal integrity and acid gas content allowing for more informed understanding of exploration risk.Classical geochemical techniques that analyze residual pore fluids are often inadequate for determining where petroleum fluids have been, and are typically hampered by contamination, fractionation and alteration issues. Subsurface fluid processes leave resolvable chemical traces in the form of crystallographically trapped fluids in diagenetic cements and healed microfractures. These fluid inclusions are not subject to evaporation during sample storage or loss of light ends during sampling from depth. They persist in the geologic record long after the parent fluids have moved on, but are continuously formed even up to the very recent past. Hence, fluid inclusion studies have the potential to provide a detailed account of petroleum distribution and charge history.
Deliverables will consist of:
1) A comprehensive report on FIS (petroleum distribution and type; seals, proximal undrilled pay, etc.), reservoir quality, fluid inclusion geochemistry and timing of petroleum emplacement for each well.
2) A summary report of regional and local trends, including exploration significance.
3) Digital files and hard copy of all data and photomicrographs.
Estimated Delivery Date: October,2000. Pricing: $45,000 CDN
