.... Three pairs of SAGD operation began in April of 1997 after three months of circulation. Many interesting characteristics were identified in the injection and production history. During the first year of operation, pressure and oil production rates decreased when steam injection rates were reduced. After...

... sands. Bitumen is defined as oil that is less than 10 API and will not flow to a well in its naturally occurring state. Steam assisted gravity drainage (SAGD) is a promising in-situ thermal recovery method, having the advantages of lower energy requirements and higher recovery factors over other steam...

... Abstract Non-condensable gases (CH 4 , CO 2 , and H 2 S) are present and play an important role in the thermal efficiency of SAGD. However, the role of these gases is not well understood and it is regarded by some people as beneficial, yet detrimental by others. The characterization of the gas...
