Outline of the SAGD Method

JACOS pioneered the establishment of the Steam-Assisted Gravity Drainage (SAGD) method, a method using steam to extract bitumen (ultra-heavy oil) from the oil sands layer.

The Steam Assisted Gravity Drainage (SAGD) method is a method to extract bitumen from the oil sands layer, using high-temperature, high-pressure steam to heat the oil sands layer and providing liquidity to the bitumen.

In the SAGD method, a pair of horizontal wells are first drilled. Steam is then added to the upper well to heat the oil sands layer, and the bitumen, which flows fluidly through the layer, is collected and produced in the lower well.
