BACKGROUND OF THE INVENTION. This invention relates to an improvement in the operation of an oil sands hot water extraction plant. In the extraction of oil from oil sands, oil bearing material is mined, usually by a bucket wheel excavator or dragline, and is transported for hot water extraction processing in which it is mixed with hot water such that the bitumen floats as …
The oil sands occur in three major areas of the province: the Athabasca River Valley in the northeast, the Peace River area in the north, and the Cold Lake region in east central Alberta. "Such heavy oils (even some not so heavy oils) are often difficult to refine because of their viscosity and propensity for being unstable and precipitating ...
Production of liquid hydrocarbon mixtures from oil-shale, oil-sand, or non-melting solid carbonaceous or similar materials, e.g. wood, coal (mechanical winning of oil from oil-shales, oil-sand, or the like B03B) [2013-01]
For oil sands technologies, there have been steady patent applications, since the first patent was applied in 1969. The number of patents applied appeared to …
A system and method for immediately separating oil sands into three layers uses a logwasher with paddles that mixes the oil sands with hot water and steam. The three layers of bitumen, clay/sand/water slurry and rock separate effectively and immediately and are not re-mixed in further processing as was conventional, further producing a clay fraction from the fines for …

A method of increasing a dwell time of a slurry facility at a given ore processing location by using a mobile oil sands mining system. The method involves coordinating the operation of at least two mining conveyors to facilitate mining at least one arc-shaped sector of ore that otherwise would not be within operational reach of the slurry facility at the ore processing location.
The Shell deal came about in 2007, when Sonic worked with Western Oil Sands to develop new technology to separate bitumen from sand for use at the Athabasca Oil Sands Project. Shell added research and intellectual property that will be incorporated into the patent.
The oil sands layers contain substantial amounts of bitumen. Beneficially, the oil sands are near-surface and are largely amenable to open-pit mining. Generally, Athabasca oil sands are composed of siliceous material with grains having a size greater than that passing a 325 mesh screen (44 microns). The oil sands also contain clay and silt.
Oil sands samples were collected from a field test site and frozen. A frozen oil sand sample was allowed to thaw and reach room temperature. The circulating water bath was heated to 55° C. (or desired temperature) and allowed to flow through the heating jacket. An oil sands sample (˜500 g) was then added to the beaker within the BEU.
Extraction of oil shales and tar sands. United States Patent 4108760. Abstract: This invention relates to the extraction of oil shales and tar sands by using a solvent under supercritical conditions at a temperature within 200° C. or its critical temperature in order to effect extraction of kerogen from the sand or shale.

A process for flocculating and dewatering oil sands fine tailings in a pipeline is provided, comprising: pumping a tailings feed having a solids content in the range of about 10 wt % to about 45 wt % through a pipeline; injecting an effective amount of a polymeric flocculant into the tailings feed to provide an initial quick dispersion of the polymeric flocculant into the tailings feed; and ...
Vanadium can be recovered efficiently from ash from oil sands of western Canada by a process disclosed in this patent. The ash is roasted in air with sodium chloride at from 700/sup 0/-950/sup 0/C for 2-12 hours to form a calcine. The calcine is then leached with aqueous leachant of pH 5-12 at temperatures up to the boiling point.

The process according to claim 1, for oil and gas production by Shale fracking, oil Sands, Biomass and gas hydrates involves, (a) injecting CO 2 with hydrogen peroxide in the well bores in the concentrations as described in patent embodiment in the body of patent.
1. A method of removing fines and coarse particles from tailings formed during recovery of bitumen from oil sands, the method comprising: forming a slurry comprising water and oil sands; separating bitumen from tailings in at least one of a primary separation vessel or a secondary separation vessel, the tailings comprising a solution having fines and coarse …
In hydrocyclone.}, Oil from subsurface tar sands having an injection means in fluid communication with a production means is recovered by injecting an oil-external miceller dispersion at a temperature above 100/sup 0/F into the tar sands and displacing it toward the production means to recover hydrocarbon through the production means.
A system for extracting bitumen from oil sands includes an extractor tank having a reaction chamber. An input port is provided at the upper end of the extractor tank for the purpose of introducing oil sand into the reaction chamber. A liquid extractant is heated and then pumped, under pressure, into the reaction chamber through a plurality of jet inlets to suspend the oil …
Oil sands had not received enough attention due to high production cost. However, as oil price significantly increases, oil sands are receiving more and more interest as unconventional crude oil. The value and applicability of oil sands can be enhanced by upgrading oil sands bitumen to produce synthetic crude oil (SCO). This study analyzed 213 ...
The companies of the Canadian oil sands innovate in the fields of applied/process chemistry and mechanical engineering. This less-than-surprising finding was established through a key-word search of the expression "Oil Sand" in the title of patent documents publicly available at the website of the Canadian Intellectual Property Office (CIPO).
