A method for extracting bitumen from a subterranean oil sand deposit including: drilling a portion of the deposit; fragmenting the drilled deposit; drilling of the fragmented deposit to allow for flooding, wherein one or more wells are drilled to provide access to the deposit and retrieval of extracted bitumen, to form a drilled fragmented deposit; flooding the drilled fragmented deposit with a first flood volume of fluid to permit the first flood volume of fluid to admix with the fragmented first portion, to release heavy oil from any inert material so that the heavy oil floats within the first flood volume of fluid in the drilled fragmented deposit to form a flooded first portion; recovering the heavy oil; and repeating the above for each additional portions. |
