Oil sands mining vs in situ
In-situ extraction methods are used to recover bitumen that lies too deep beneath the surface for mining (greater than 75 metres underground). Currently, 80% of oil sands reserves are accessible via in-situ techniques. Steam Assisted Gravity Drainage (SAGD) is currently the most widely used in-situ recovery method. 2019 MONTHLY BITUMEN PRODUCTION FROM MINING thousand bbl/day • data by AER.

Given that a majority of production comes from in-situ operations and only a very tiny surface area of the mineable oil sands area has been disturbed, let's start off with images of steam-assisted gravity drainage and other in-situ sites to answer the question The resource potential for in situ oil sands extraction is huge. Surface mining is only feasible for the shallow oil sands deposits found north of Fort McMurray, which means that 80 percent of the There are two different methods of producing oil from oil sands: open-pit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through open-pit mining. Bitumen is extremely thick and too heavy to flow or be pumped, So what’s the difference between mining and in situ? Oil sands mining tends to capture the bulk of negative media and public attention because the visuals are compelling. By comparison, in situ drilling has a much smaller footprint because it can cluster many wells on one pad so it takes up much less space. Most water used in oil sands development is recycled – 80 percent for established mining operations and approximately 94 percent for in-situ recovery. However, some new water is required and comes from a variety of sources, including on-site drainage, collected precipitation (rain and melt water), underground salt water (brackish) aquifers, and the local watershed such as rivers.

4 Jan 2019 This is known as in situ oil sands mining. Oil sands deposits are usually split into two types of deposits. Shallow deposits are located within
An in-situ processing plant is generally much smaller and simpler than an oil sands mining facility. However, bitumen can only be extracted in-situ if the oil sands deposit is deep below the surface. Most in-situ deposits lie at least 200 meters below grade. In situ operations require more energy than oil sands mining to produce a barrel of bitumen. As a result, in situ operations generate two and half times as much greenhouse gas per barrel of bitumen as oil sands mines (91 kg/barrel vs. 36 kg/ barrel, excluding the emissions associated with bitumen upgrading). In situ oil sands mining. Oil sands deposits that are greater than 75 meters below the ground surface are usually extracted without removing the overlying rock and dirt. This is known as in situ oil sands mining. Oil sands deposits are usually split into two types of deposits. Only 20% of the Alberta oil sands is mineable (by surface area) The remaining 80% of oil is too deep and can only be extracted using in-situ methods with minimal land disturbance. Oil sands surface area: 142,000 km2. Mineable oil sands area cleared or disturbed: 767 km2. In 2017, In Situ Water Use [Tableau] projects used almost 18 million cubic metres of nonsaline water (26 per cent of all water allocated for in situ oil sands projects) to produce over 546 million BOE—meaning that for every BOE produced, 0.20 barrels of nonsaline water was used. 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 methods depends on the resolution of two major issues: 1) reducing the viscosity of bitumen so that it will flow, and 2) recovering the bitumen from deep within the earth (OSDC 2008c). Overcoming these challenges requires substantial energy and water, and in situ methods are expensive compared to mining.
17 Jan 2008 Oil sands, a mixture of sand, bitumen (a heavy crude that does not flow naturally), and water, can be mined or the oil can be extracted in-situ
21 Jul 2016 elements may help to distinguish natural versus oil sands mining inputs to surface waters. First, we examined changes in these three elements
