Paper Number: SPE-178917-PA
Published: 17 November 2015
.... The significant HDN and HDS removal coupled with decreased viscosity, increased °API value, and light hydrocarbons indicate upgrading of the original Athabasca bitumen for all three tests. The results showed that although the regenerated catalyst Tests 2 and 3 lost HDN activity compared to the fresh catalyst...

... days) at different air-flow rates and at temperatures of 5, 15, and 25C. The solvent content, density, and viscosity of the films were measured after different weathering times. A second set of tests at 15C was performed on both dilbit and light-crudeoil films on water. As expected, the mass-transfer...

... for 100- kHz frequency. Introduction Viscosity is a major obstacle in the recov- ery of bitumen in oil-sand reservoirs. Ther- mal recovery is considered the most ef- fective method for lowering viscosity, and steam-assisted gravity drainage (SAGD) is the most promising thermal recovery tech- nique applied...

... may not support a wormhole- network assumption. The absence of a wormhole in these fields can be explained with a lower oil viscosity and lack of strong directional geomechanical trend, resulting in sand settledown and sand pileup inside the well (Sanyal and Al-Sammak 2011). The wormhole branching...
