More than half of the total world oil reserves are heavy oil, extra heavy oil, and bitumen; however their catalytic conversion to more valuable products is challenging. The use of submicronic particles or nanoparticles of catalysts suspended in the feedstock may be a viable alternative to the conversion of heavy oils at refinery level or downhole (in situ upgrading). In the present work, molybdenum sulfide (MoS2) particles with varying diameters (10000–10 nm) were prepared using polyvinylpyrrolidone as capping agent. The prepared particles were characterized by DLS, TEM, XRD, and XPS and tested in the hydrodesulfurization (HDS) of a vacuum gas oil (VGO). A correlation between particle size and activity is presented. It was found that particles with diameters around 13 nm show double the HDS activity compared with the material with micrometric particle sizes (diameter ≈ 10,000 nm).

The estimation of the share of hard-to-extract oil reserves in the deposits of Russia varies by different sources, in a fairly wide range (from 30 to 70 %). Due to the absence of a common approach to their definition, the variety of parameters used to estimate this share and fundamentally different conditions for the development of the groups of reserves classified as hard-to-extract become challanging. A significant share of the proven oil reserves of Russian oil fields - about 34 % (6.3 million tons) - belongs to heavy (oil density more than 0.871 g/cm3) and super-heavy (oil density more than 0.895 g/cm3). In general, the share of high-viscosity and super-highviscosity oils is about 13% (2.4 million tons). The largest share refers to the deposits of three districts. In lowpermeable collectors (permeability less than 0.05 μm2), huge reserves are concentrated – 8.2 million tons or 44.6 % of all oil. Comparison of oil extraction and reserves structure indicates a good correlation for oil extraction from low-permeable collectors in 41.8 % with reserves percentage in 44.6 % as well as a relatively good correlation in super-heavy oil in 13.4% with reserves percentage in 18 % and low rates for super-high-viscosity oil in 1.7% with reserves perecentage in 6 %. Significant proven reserves of high-viscosity oil in Russia indicate the possibility of increasing production with the introduction of modern, existing and proven, technologies under appropriate economic conditions. Full-scale involvement in the development of only the largest deposits of high-viscosity oil would allow the Russian Federation to produce at least 25-30 million tons in the medium term.

EnCana Resources is enjoying economic success at their Steam Assisted Gravity Drainage (SAGD) research facility at Senlac, Saskatchewan. This has been achieved largely due to the successful application of new and innovative ideas and technologies. During the summer of 2001, PanCanadian Energy (now EnCana Resources) made use of a novel buried piping technology at the Senlac Thermal Project to solve the problem of connecting distant well pairs to the processing plant. The four-kilometer pipeline system accommodated a thermal growth of approximately 12 meters over its entire length using buried expansion loops and “Z” bends. The pipeline was installed at an estimated 30% cost savings over conventional above ground methods. This paper summarizes the successful installation of this unique piping technology at Senlac and its applicability to future commercial SAGD projects in the context of the heavy oil reserves in Alberta.
