摘要： A method for remediation of at least one cold spot in a producer well in a Steam Assisted Gravity Drainage (SAGD) process to increase hydrocarbon recovery from a hydrocarbon reservoir, wherein the SAGD process occurs at a site including an injection well, a production well and a steam chamber. The method includes shutting the production well and maintaining or increasing steam injection through the injection well until pressure in the steam chamber increases. The production well is then resumed while continuing steam injection at rates for normal SAGD or greater until reservoir pressure reaches normal operational pressure. Optionally, the injection/production is adjusted to return to normal SAGD operation.

摘要： Staged crushing combined with water addition and mixing is practiced at the mine site to prepare an oil sand slurry ready for hydrotransport. More particularly, as-mined oil sand is crushed to conveyable size (e.g. —24″) using a mobile crusher. The pre-crushed ore product is conveyed to a dry ore surge bin. Ore is withdrawn from the bin and elevated to the upper end of a slurry preparation tower having downwardly aligned process components to enable gravity feed. The ore is further crushed in stages to pumpable size (e.g. —4″) by a stack of crushers and water is added during comminution. The ore and water are mixed in a mixing box and delivered to a pump box. The surge bin and tower are relocatable. Screening and oversize reject treatment have been eliminated to achieve compactness and enable relocatability.

摘要： The invention provides an improved method for extracting heavy oil or bitumen contained in a reservoir. The invention involves directing the formation of a solvent fluid chamber through the combination of directed solvent fluid injection and production at combinations of horizontal and/or vertical injection wells so as to increase the recovery of heavy oil or bitumen contained in a reservoir. The wells are preferably provided with flow control devices to achieve uniform production.

摘要： An aqueous aerated oil sand slurry is conditioned in a pipeline and then spun within an elongate vessel of circular cross-section, to cause bitumen droplets in the slurry to coalesce. This increases the probability that the droplets will become aerated by contact with air bubbles. The slurry is then subjected to separation of the sand and bitumen.
