Description
2:00 TEMPERATURE DEPENDENCE OF OIL SAND PENETRABILITY, Peter Lauzon * and Ben de Mayo, University of West Georgia, Carrollton, GA 30118. The Athabasca oil sand deposits of Alberta, Canada, contain perhaps the largest deposit of petroleum in the world. The commercial extraction of this resource is highly dependent on the mechanical properties of the oil sands. One potentially important measure of these properties is the temperature dependence of the penetrability factor of the sands (Durgunoglu and J. K. Mitchell, Static Penetration Resistance of Soils, April 1973, Space Science Laboratory, Series 14, Issue 24, University of California, Berkeley). We have experimentally measured this factor by recording the force necessary to insert a 0.625 cm rod into oil sand at different temperatures. Vernier Software equipment was used to record the temperature, the force and the penetration depth at a rate of 2 times per second. The results were plotted and analyzed using Microsoft Excel and Deltagraph software. A power function PF(T) = 0.2585 * T^(-0.826) N/mm provided a good fit to the data, where PF is the penetration factor and T is the temperature in C. Acceptably pliant oil sand is found to be achievable at modest temperatures, a fact of benefit to the oil sand extraction companies.

Hasbun, Ben de Mayo and Peter Lauzon *, University of West Georgia, Carrollton, GA 30118. Given the vast amount of crude oil which exists in Alberta's oil sands, we studied a sample from Athabasca in order to characterize the relationship between applied force, penetration depth, and temperature. From the collected data the force was modeled as a function of temperature and depth. Using this information, an analysis of the energy associated with the amount of work in penetrating the oil sand to a particular depth was made. We, thereby, obtained an analytic behavior of the energy as a function of temperature. This, in turn, is related to the cost of mining the oil sand and it is found that it takes more energy to achieve penetration at lower temperature. Additionally, by the nature of the system, we relate our applied force to a viscous force similar to Stokes' Law, and calculate an effective viscosity of the oil sand as a function of temperature.
