Project Location:  Nechako Basin

Strategic Focus Area:  Energy-Resources

Summary



Magnetotelluric Survey Project Area The Nechako Basin is an interior basin within central British Columbia wherein only limited hydrocarbon exploration has been carried out. This can be attributed to a number of factors particularly the limited number of outcrops of the rocks of interest. Another of the challenges in this basin is imaging potential sedimentary sequences through Paleogene and Neogene basaltic flows. Classic seismic techniques have had mixed results due to energy absorption and reflection by the volcanic units. These rocks also hamper the interpretation of gravity and magnetic data. As MT is sensitive to an independent parameter, namely electrical conductivity, it may be a useful tool for exploring the subsurface of the Basin. As such, the primary objectives for this project are the determination of the appropriate acquisition parameters for magnetotellurics as a tool for both oil and gas exploration and geological characterization of the Nechako Basin, and to directly evaluate the use of the technique via a test survey.
