Suppliers work closely with oil sands operators to optimize the design of their vehicles, constantly improving fuel efficiency and reducing downtime. A payload of 400 tonnes is now considered the norm for oil sands mining operators. The 4000 hp Caterpillar 797F is one of the most popular models for newer mining fleets. A bigger truck means fewer trips to the processing plant, which greatly improves mining efficiency. Smaller haul trucks are normally reserved for removal of overburden and

Energy efficiency is expected to improve to an average of 900 cubic feet (25 m 3) of natural gas or 0.945 gigajoules (262 kWh) of energy per barrel by 2015, giving an EROEI of about 6.5. Alternatives to natural gas exist and are available in the oil sands area. Alberta's oil sands contain on average about 10% bitumen, 5% water and 85% solids. Most of the solids are coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10-30% by weight. Bitumen is a heavy complex hydrocarbon, contained within the oil sands deposit. Environmental impacts of oil sands The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel , negative environmental effects arise as a result of the extraction, upgrading , and processing of bitumen from the oil sands. Oil sands, or tar sands, are sand and rock material which contains crude bitumen, a dense, viscous form of crude oil.Bitumen is too thick to flow on its own, so extraction methods are necessary. There are four commercial plants producing bitumen from surface minable oil sands, using some version of the Clark Hot Water Extraction (CHWE) process, which was developed in the 1930s by Dr. K.A Emission of greenhouse gases: Oil sands are too deep and the extraction of these oils lead to the emission of a high amount of carbon gases and other greenhouse gases. 4. Affects ecosystem: Clearing of trees, brush, topsoil and clay on oil sand deposit areas affects the ecosystem of the local animal species. 5.

These features make it possible for hydrocarbon extraction from oil sands feedstock at mild temperatures of 50-60 C degrees with no vacuum or pressure applied. There's no need for tailings ponds because the only elements that leave the closed-loop system are the extracted crude oil and the cleaned sands, which can be placed back in the earth or sold as clean sand for construction or fracking purposes.

19 Feb 2013 Tar sands retrieved by surface mining has an EROI of only about 5:1, sources have much lower efficiencies than conventional gas and oil, 

But tar sands oil is in a category all its own. Tar sands retrieved by surface mining has an EROI of only about 5:1, according to research released Tuesday. Tar sands retrieved from deeper beneath the earth, through steam injection, fares even worse, with a maximum average ratio of just 2.9 to 1.
