Short description: |
Lecture presents methods of usage of borehole data to reconstruct geometry of structures and physical properties of rocks deep below the Earth surface. |
Full description: |
Subject presents possibilities of extension of superficial geological data by adding extra dimensions for subsurface geological mapping purposes. This subsurface data are acquired mainly from boreholes, mostly from borehole cores. The most popular method is partial coring, and full geological profile is made by using well logging (measurements along the drill hole), and superficial geophysics (seismic, gravimetric, magnetic, magnetotelluric, geoelectric etc.). Seismics is the database for construction of the subsurface geological maps. Presently 3D seismic becomes increasingly popular, enabling constructing subsurface geology spatial models directly from digital seismic data. Methods of numerical presentation of subsurface geology and 3D visualisation of geological structures are discussed. |
