Simulation Study of Steam Assisted Gravity Drainage (SAGD) in Fractured Systems [PDF]
Oil & Gas Science and Technology - Revue de l'IFP, 2009 The Steam Assisted Gravity Drainage (SAGD) process, a developed Enhanced Oil Recovery (EOR) process to recover oil and bitumen, has been studied theoretically and experimentally in conventional reservoirs and models and is found a promising EOR method for certain heavy oil reservoirs.

Design of flow control devices in steam-assisted gravity drainage (SAGD) completion [PDF]
Journal of Petroleum Exploration and Production Technology, 2017 Abstract Commercialization of the steam-assisted gravity drainage (SAGD) process has made recovery of heavy oil/bitumen possible in a number of reservoirs hindered by hydrocarbon immobility. However, the economics of this process are highly sensitive to the efficiency of steam creation, delivery, and use, with a successful and unsuccessful SAGD well ...

The Canadian Journal of Chemical Engineering, Volume 101, Issue 11, Page 6135-6150, November 2023., 2023 Abstract The required steam for steam‐assisted gravity drainage (SAGD) oil sands operations is generated using a once‐through steam generator (OTSG) that is fed with relatively poor quality process water. Industries have reported possible solid particle erosion‐related failure in the OTSG boiler tubes because of the transport of precipitated dense ...
