In situ tar sands

In situ tar sands

In Situ refers to methods of oil sands production that use drilling and steam to produce bitumen. The most common in situ method is called Steam Assisted  Dec 18, 2013 Mining versus in situ tar sands extraction. Unfortunately, the carbon emissions associated with extracting tar sands could increase over time, as in  In situ methods are used to recover bitumen that lies too deep beneath the surface for mining (about 80% of the oil sands in Alberta). The success of in situ  The majority of Alberta's oil sands—about 90%—are too far below the surface to be quarried. Accessing the oil in these deposits requires a method of extraction 

Extracting bitumen from tar sands—and refining it into products like gasoline—is significantly costlier and more difficult than extracting and refining liquid oil. Common extraction methods include surface mining—where the extraction site is excavated—and “in-situ” mining, where steam is used to liquefy bitumen deep underground.

15 Then, because bitumen is so thick, it requires either dilution or upgrading before it can be transported by pipeline. in Situ extraction. For tar sands deposits that  of studies compiled was 14% greater emissions for tar sands produced from surface mining. For in-situ methods, the average found was 25% greater emissions 

Sep 25, 2014 As the name "tar sands", or oil sands, implies, the heavy crude is found mixed in with sand, clay, and water, which must be removed, then the 

Dec 16, 2016 Oil Sands Deposits in the World. Actual Production and Projected Production in Year 2040 From Surface Mining and In Situ Extraction [Wykes  Feb 13, 2020 Additionally, natural gas is used in oil sands mining to heat water to separate bitumen from sand. It is also used to create steam in upgrading to  Feb 19, 2013 In other words, 25 units of oil-based energy are obtained for every one unit of other energy that is invested to extract it. But tar sands oil is in a  Oil sands are found in various countries throughout the world, but in vast quantities in Alberta and Venezuela. Alberta's oil sand reserves are estimated at 1.7 to 2.5  Aug 29, 2016 Canada's oil sands are notoriously dirty, but in situ extraction—which involves blasting high-pressure steam into the ground to warm and soften
