SAGD and Heavy Oil Development

Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS)

SAGD/CSS is an unconventional resource development that is widely used to extract bitumen from underground oil sands deposits. These methods involve injecting steam into sub-surface oil sands deposits to heat the bitumen locked in the sand, thereby lowering the viscosity allowing it to flow and to be extracted. In Alberta alone, 80% (or 135 billion barrels) of the oil sands are located in these underground deposits.

SAGD operations have become more common as technology continues to advance. Starting in the early 2000’s, 5 SAGD projects were underway in Alberta, as of 2017 there is a total of 64 ongoing SAGD operations and 9 CSS projects. In 2016, the total in-situ production of bitumen was 1.4 million barrels day.

In-situ oil sands production is expected to reach 3 million barrels per day by 2040, according to the National Energy Board (NEB).


Chinook Consulting and its consultants have been involved in the drilling and geological reporting from the very beginning of SAGD development and we are committed to providing our clients the highest level of service available.


It’s important to know what we can offer.
