Pore-level Investigation of Heavy Oil Recovery Using Steam Assisted Gravity Drainage (SAGD)

Successful application of gravity drainage process, facilitated with steam injection, using horizontal wells in various field<br>tests, especially within Canada, indicates that high recovery factor and also economical steam to oil ratios are achievable.<br>Steam Assisted Gravity Drainage recovery scheme was theoretically developed, pilot tested and commercialized in Canada,<br>however, there are still several technical challenges to be solved in this process.
