The purpose of this project is to provide AOSERP with a preliminary understanding of the state of the art of in situ bitumen recovery technology, the most probable application and rate of application of that technology to the Athabasca deposit, and the resultant implications for the environment and people of the area. This overview is aimed at providing Insight and general direction to research managers and scientists regarding in situ oil sands development. The report outlines oil sands deposits in Alberta in general and in the AOSERP study area in particular that are relevant to in situ technology and development. Current and proposed methods for in situ recovery are discussed including the technology, potential environmental affects, and the likelihood of commercial use. A possible development scenario is explored and an environmental impact matrix is used to assess the possible effects of this development scenario on Land, Air, Water, and Human systems in the region. The report has been reviewed and, although the conclusions do not necessarily reflect the views of Alberta Environment or Fisheries and Environment Canada, it is the impression of AOSERP management that the researchers have provided a reasonable prediction of in situ development. The mention of trade names for commercial products does not constitute an endorsement or recommendation for use.
