Bankers has a variety of recovery methods from which to choose to access multiple hydrocarbon zones.
(Cyclic steam stimulation) Steam saturates the oilsands formation, softening and diluting the bitumen so it can flow to the well during the production phase. This can be done in both a vertical and horizontal wellbore.
Conventional chops (Vertical Reactivations)
Progressive cavity pumps are utilized to effect Cold Heavy Oil Production with Sand from the reservoir.
Uses the same method as conventional chops, but instead of going straight down, the pipe is curved to access resources on the same horizontal level rather than from varying depths.
Horizontal wells (SAGD method)
A recovery technique for extraction of heavy oil or bitumen that involves drilling a pair of horizontal wells one above the other; one well is used for steam injection and the other for production.
Vertical wells (waterflood method)
A method of secondary recovery in which water is injected into the reservoir formation to displace residual oil. The water from injection wells physically sweeps the displaced oil to adjacent production wells. Potential problems associated with waterflood techniques include inefficient recovery due to variable permeability, or similar conditions affecting fluid transport within the reservoir, and early water breakthrough that may cause production and surface processing problems.
