Effects of Lean Zones on Steam-Assisted Gravity Drainage Performance
A thorough understanding of the effects of lean zones and the improvement of steam-assisted gravity drainage (SAGD) operations with such heterogeneities is critically important for reducing the disadvantages of lean zones.

Experimental and Numerical Investigation on Infilled Vertical Well LASER-Assisted SAGD
In the SAGD process with dual horizontal wells in heterogeneous reservoirs, the injection pressure of steam huff-n-puff by infilled interwell vertical wells is too high, and the heat communication between SAGD wellpairs and infilled wells is too long ...

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 ...

Drawbacks in phase change models in simulating flashing of steam with a subsaturation downstream boundary condition. Abstract The development of phase change models applicable to a wide range of temperatures, pressures, and mass flow rates is primarily limited by the metastable or partially stable behaviour of the fluid. Due to this, the fluid does not

Strategies of SAGD Start-Up by Downhole Electrical Heating
The SAGD start-up process normally circulates steam in both the injector and producer, which consumes a large amount of steam, requires the high cost of high-temperature-produced liquid treatment, and unavoidably results in preferential communication in ...

Impact of Shale Barriers on SAGD and ES-SAGD Performance
Shales are the common type of heterogeneity present in the oil sand reservoirs. Shale barriers usually have very low permeability leads to obstruction for fluid flow inside the reservoirs towards the wellbore. SAGD (steam assisted gravity drainage) and ES-SAGD (expanding solvent assisted gravity drainage) rely heavily on gravity drainage, and thus the ...
