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.
Des procédés et des systèmes surveillent des conditions dans un réservoir dhydrocarbures avec un puits dobservation multilatéral. Le puits dobservation peut détecter le développement vertical dune chambre à vapeur qui se forme dans le réservoir pendant des opérations de récupération dhydrocarbures thermiques. En outre, le puits dobservation peut comprendre des branchements qui sétendent pour former des alésages verticaux avec des capteurs de température pour la surveillance, qui peut se produire pendant les opérations de récupération effectuées dans dautres puits, étant donné que le puits dobservation peut être dédié uniquement à la surveillance.
