Steam Assisted Gravity Drainage (SAGD)

Introduction

  • The SAGD process uses steam to heat the bitumen in the formation so that it is able to flow to the producing well and to surface.
  • The technology incorporates horizontal well pairs with a production well (the producer), near the bottom of the oil sand zone and a parallel steam injection well, (the injector), located above the producer.
  • Steam is injected into the injector where it contacts the oil sand and mobilizes the bitumen. The bitumen flows by gravity to the producer, where it is produced to surface.

Where it is Used

  • Steam Assisted Gravity Drainage is a form of "in situ" bitumen recovery, used where the bitumen deposits are too far below ground to extract them with open cast mining
