The compression behaviour of Canadian oil sands
International audience The compression behaviour of Canadian oil sands was investigated by running high stress oedometer compression tests up to 65 MPa. X-Ray microtomography investigation confirmed the significant disturbance affecting the core samples, showing large pores located between dense int...
