Primary seismic wave (P) at 250-350 km compared to measured wave to 0.3 km from GNOME nuclear explosion

Laun, Philip Royal 09 December 1964 (has links)
The first cycle of seismic waves recorded at distances of 45, 300 and 355 km. from the GNOME nuclear explosion was used to determine whether the near source wave characteristics at 0.3 km. could be determined from distance measurements. Both head wave and body wave propagation were considered. First the recorded signals at distance were inversely propagated back to the near source region as head waves, and secondly, the measured source at 0.3 km. was propagated out to 300 km. from the source as a body wave. In both cases, restricted comparisons between theory and observation can be made, but the comparison appears to favor the body wave type of propagation. More research is needed to make a more conclusive choice between the two modes of propagation. Methods were developed which can be used to determine source motion from distance measurements when the data are sufficient to do so. / Graduation date: 1965

A conceptual approach to subterranean oil sand fragmentation and slurry transport

Lam, S.C. Anthony 11 1900 (has links)
Oil sand deposits are found at three depths; shallow, intermediate, and deep. Shallow deposits are processed by surface mining while deep deposits are processed using thermal extraction methods. There are currently no production methods to extract oil sand at intermediate depths. The motivation for this research is to demonstrate the technical applicability of methods to access oil sand that is too shallow for thermal extraction methods and too deep for economical surface mining. This work consisted of developing a system concept as a method for accessing, fragmenting, and removing oil sand at intermediate depths. A technical analysis and a cost estimate were also performed. In addition, the applicability of a comparative methodology was demonstrated with case studies. A key gap in the understanding of how to implement the system concept is tooling design and power requirements for fragmenting oil sand and interburden; and so a set of laboratory experiments was conducted to investigate the power required to cut oil sand. Oil sand blocks were formed from oil sand samples for the experiments. These blocks underwent various tests to examine their characteristics. Tests included: shear testing, extraction testing, porosity measurements, and scanning electron microscopy. Lab-scale experiments were conducted in dry, wet, and frozen conditions in support of the fragmentation aspect of the system concept. Thermal imaging was used to qualitatively view temperature variation during the testing process and cutter wear was viewed using a digital microscope. Results were compared against a steady-state cutting model with recommendations for future work.
