Comprehensive Multi-Stage Analytical Treatment of Steam-Assisted Gravity Drainage SAGD
SPE Annual Technical Conference and Exhibition, 2018Abstract A comprehensive analytical model of the Steam-Assisted Gravity Drainage (SAGD) process is developed, encompassing steam chamber rise, sideways expansion, and the confinement phases. Results are validated using experimental and field data.

Understanding the Steam Hammer Mechanism in Steam-Assisted Gravity Drainage (SAGD) Wells
SPE Heavy Oil Conference-Canada, 2013Abstract Steam-assisted gravity drainage (SAGD) is one of the successful thermal recovery techniques applied in Albertan oil sands reservoirs. When considering in situ production from bitumen reservoirs, viscosity reduction is necessary to mobilize bitumen thereby flowing toward production well.

Simulation of Early-Time Response of Single-Well Steam Assisted Gravity Drainage (SW-SAGD)
Proceedings of SPE Western Regional Meeting, 1999Abstract Steam assisted gravity drainage (SAGD) is an effective method of producing heavy oil and bitumen. In a typical SAGD approach, steam is injected into a horizontal well located directly above a horizontal producer. A steam chamber grows around the injection well and helps displace heated oil toward the production well. Single-well

The Role of Emulsions in Steam-Assisted-Gravity-Drainage (SAGD) Oil-Production Process: A Review
SPE Journal, 2019SummaryStudies that investigate and attempt to model the process of steam-assisted gravity drainage (SAGD) for heavy-oil extraction often adopt the single-phase-flow assumption or relative permeability of the moving phases as a continuous phase in their analyses.

Abstract As oil reserves decrease, the level of difficulty to extract oil increases. With this increased difficulty, the service conditions involved in Steam Assisted Gravity Drainage (SAGD) are increasingly more aggressive. In an effort to maintain low raw material prices without sacrificing performance, duplex and superduplex stainless

Flexible Cement Improves Wellbore Integrity for Steam Assisted Gravity Drainage (SAGD) Wells
International Thermal Operations and Heavy Oil Symposium, 2008Abstract Well integrity is a key requirement for continuing heavy oil development and production. Cement sheath integrity is crucial to maintaining zonal isolation, which prevents unwanted fluid migration, especially oil, gas and steam, outside of the wellbore.

Hydrocarbon Depletion of Athabasca Core at Near Steam-Assisted Gravity Drainage (SAGD) Conditions
Energy & Fuels, 2010The present study shows the feasibility of preparing hydrocarbon (HC)-depleted cores with a laboratory setup operated at near steam-assisted gravity drainage (SAGD) oil production conditions (200—240 °C and 2.5 MPa). One Athabasca core was selected for this purpose.

Steam Assisted Gravity Drainage (SAGD):Influence of Geomechanical Processes on Absolute Permeability
2013Alberta is recognized by its vast oil sands reserves. The applications of established thermal processes, such as SAGD, are commonly required to achieve economic hydrocarbon recovery. Steam injection causes pore pressure and temperature changes that influence the reservoir geomechanical properties with a related impact on flow properties such as ...

Proceedings of SPE Western Regional Meeting, 2010
Abstract Steam Assisted Gravity Drainage (SAGD) is one successful thermal recovery technique applied in the Athabasca oil sands in Canada to produce the very viscous bitumen. Water for SAGD is limited in supply and expensive to treat and to generate steam. Consequently, we conducted a study into injecting high-temperature solvent instead
