MULTILATERAL OBSERVATION WELLS

摘要

Methods and systems monitor conditions in a hydrocarbon reservoir with a multilateral observation well. The observation well may detect vertical development of a steam chamber that forms in the reservoir during thermal hydrocarbon recovery operations. Further, the observation well may include branches that extend to form vertical bores with temperature sensors for the monitoring, which may occur during the recovery operations performed in other wells since the observation well may be dedicated to only the monitoring.

1. A method of monitoring conditions in a hydrocarbon reservoir, comprising:
injecting steam into the reservoir; producing a mixture of hydrocarbons and condensate of the steam from the reservoir; and detecting vertical development of a resulting steam chamber in the reservoir with a multilateral observation well having temperature sensors disposed in branched bores of the observation well.
