A SAGDOX satellite system for recovering hydrocarbons includes a central SAGDOX site, at least one SAGDOX satellite site, and a pipeline corridor for communication between the central SAGDOX site and the SAGDOX satellite site. The satellite system is designed to recover hydrocarbons using a SAGDOX process at the satellite site and transfer recovered hydrocarbons to the central site.

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.
