The BC Energy Plan calls for the provincial government to partner with industry, the federal government, and Geoscience BC to undertake comprehensive research in the Nechako Basin and establish new data concerning the petroleum resource potential there. The Nechako Initiative - Geoscience Update, Open File 2007-1, presents interim reports on some of the geoscience projects that the Resource Development and Geoscience Branch of the Ministry of Energy, Mines and Natural Gas, Oil and Gas Division, continues to conduct and support in the Nechako region.
Energy geoscience work is difficult to conduct in the Nechako region due to the extensive blanket of Eocene and Neogene volcanics and glacial cover, which mask the rocks with hydrocarbon potential.
Exploration wells drilled in the 1960s and 1980s provide a rare and valuable glimpse into the subsurface geology of the Nechako. Much of the work reported in this volume has come from our efforts to extract new data from old exploration well records, cores and drill cuttings. Filippo Ferri and Janet Riddell report on some initial results of analyses conducted on the old drill cuttings and core, including contributions from Paul O’Sullivan of Apatite to Zircon Incorporated on new radiometric age data and apatite fission track analyses and Arthur Sweet of Geological Survey of Canada, Calgary, on new subsurface palynology results. This report also describes the surface geological field work that continues in the Nechako. Peter Mustard and James MacEachern of Simon Fraser University have conducted a detailed facies evaluation of the archived cores based on observations of sedimentological and ichnological features. Ian Smith has compiled and standardized the existing downhole petrophysical data and conducted a log analysis of each of the wells from surface casing to total depth, incorporating core, cuttings and reservoir data.
Adaptation of geophysical methods to the challenging geological conditions of the Nechako region is a key component of the strategy for improving our understanding of the subsurface. John Cassidy and Issam Al-Khoubi of the Geological Survey of Canada, Sidney, have contributed an introduction to one of the passive seismic investigations that is underway. Other Nechako geophysical pilot projects, funded by Geoscience BC and/or the Resource Development and Geoscience Branch, that are underway or beginning in 2007 include reprocessing of the 1980s-era seismic data by Arcis of Calgary, a new conventional seismic survey led by Andy Calvert of Simon Fraser University, a new magnetotelluric survey led by Jim Craven of the Geological Survey of Canada, Ottawa, and a passive microseismic test survey led by Mel Best of Bemex Consulting Limited. Updates on those projects can be found both on the Geoscience BC website and in Geological Fieldwork, an annual publication of the Ministry of Energy, Mines and Petroleum Resources.
