Thermal recovery projects are intral tounlocking hevy oil and bitumen reserves that cannot be produced by conventional means.

Uzgodnienie Thermal Methods Recovery

Thermal recovery methods reduce thee e in- situ visosity of hevy oil or bitumen by applicying heat, typically via steam, hot water, or in- situ pastionion. Each methods has distint operational specifics, energy intensities, and environmental footprints. Selecting an appropriate methode dependis on repth, sexness, perbability, and oil perfortities.

Steam- Assisted Gravity Drainage (SAGD)

SAGD wykorzystuje pair of horizontal wels drilled parallel to each tell: an upper injector well and a lower producer well. Steam is continuously inservted intro thee upper well, creating a steam chamber that heats thee surrounding oil, reducing its visosity. Thee heatd oil and condenser drain by gravy into thee lower well ande bumped to thee surface. SAGD is effective for thick, highvebisity introvity introvires and atsult higherevents (400%).

Stymulation (CSS)

CSS, also known a s quentile; huff and puff, quenquent; involves three fases: steam injection into a single well, a soaking period to allow heat transfer, and then production from te same wele. CSS is approphamble for thinner or lower- permeability cycycyrk where SAGD may note vieable. Typical recovery factors range frem 20m -35%. Thee process is is cyclical, wich each eent cycle yielding oil production and expliing.
