How do they get the oil out of the oil sands?
you get a piece of cheese you sit down then wait for the pros to do it
What does bitumen sands mean?
Bitumen sands are a natural sand or sandstone deposit which at some stage had been saturated with hydrocarbons. But which at some later stage had been exposed to conditions such that only the heavy (or long-chain) molecules remain. Or at least from which the lighter liquids and volatiles have disappeared. Actually a very common form of hydrocarbon deposit.
What is hydraulic conductivity of soil?
This depends on the soil! Cohesionless coarse grained soils with high gravel contents may have high hydraulic conductivity on the order of 1 to 1x10-1 m/s. Mixed sands and gravels are on the order of 1x10-1 to 1x10-3 m/s. Finer sands approximately 1x10-3 to 1x10-4, and fine grained soils such as silty sands may be in the range of 1x10-5 to 1x10-7 m/s. Very fine grained cohesive clay soils have very low hydraulic conductivity values ranging from 1x10-7 to 1x10-13 m/s.
What kind of energy resources might one day replace dwindling petroleum supplies?
Solar and wind renewable energy, of course. Oil shale and tar sands
How do you remove oil from oil sands?
Oil sands or bituminous sands, (more technical term) are difficult to produce because of the extremely high viscosity of the oil. Generally, the oil must be pumped out, and recovery is poor. Methods to improve recovery include heating the oil underground using steam. A thermal method called SAGD, or steam assisted gravity drainage, creates a steam zone (steam chest) immediately above the oil deposit, and wells are perforated (opened to production) at the bottom of the oil zone. The link I have included gives a general overview of various methods, and there is considerable information on the internet on SAGD and other processes. See related link.
Why is Mohr-coulomb failure envelope for clean sands tend to concave downward?
That is because the friction angle reduces with normal stress.
What is dilation of angle?
Angle of dilationThe angle of dilation controls an amount of plastic volumetric strain developed during plastic shearing and is assumed constant during plastic yielding. The value of ψ=0 corresponds to the volume preserving deformation while in shear.Clays (regardless of overconsolidated layers) are characterized by a very low amount of dilation (ψ≈0). As for sands, the angle of dilation depends on the angle of internal friction. For non-cohesive soils (sand, gravel) with the angle of internal friction φ>30° the value of dilation angle can be estimated as ψ=φ-30°. A negative value of dilation angle is acceptable only for rather loose sands. In most cases, however, the assumption of ψ = 0 can be adopted.Unlike the modified linear model the nonlinear models require to specify only the elastic modulus. A drop in the material stiffness is a result of evolution of plastic strains and corresponding redistribution of stresses. This consequently yields an instantaneous tangent material stiffness as a function of the current state of stress represented in the figure belowby an instantaneous tangent modulus ET.
What is the natural slope of dirt?
Most loose, not compacted, sands and silts have an angle of repose, measured from the horizontal, of 35 degrees.
How can the temperatures of sand and water affect the climate of the area?
The causes of effect change it
How much does a cubic meter of zircon mineral sands weigh?
Zircon has a average specific gravity of 4.65. (given by the density of the sand divided by the avg density of water) So, by re-arranging: the density is aprox 4,650 kg/m3 multiplying by g (avg) 4650 * 9.8 = 45,570N
What are bituminous sands?
Bituminous sands are oil sands , tar sands and more tecnically they're an unconventional petroleum deposit . I hope I hlped you!!
