Several sand control techniques have been used in SAGD wells in Western Canada. For most projects, slotted liners have been the sand control of choice for its economics, ease of use, and acceptable performance. Careful design of the slot geometry is crucial to maintaining...

This paper reviews the state-of-the-art experimental and theoretical methods on fines migration around Steam Assisted Gravity Drainage (SAGD) wellbores. The in-situ migratory particles can deposit in the pore space and result in pore throat plugging within the porous medium. This process...

Experimental Investigation of Near-well Fluid Mechanics on the Scaling Mechanism in Narrow Rectangular Slots
DownloadSpring 2020
This experimental study investigates the effect of near-well fluid mechanics on the scaling failure mechanism specific to SAGD production well. The scaling failure mechanism can be triggered by the pressure drop phenomenon and causes the plugging of the slots in the oilfields. The scale formation...

Near-Wellbore Salinity Effect on Sand Control Plugging by Fines Migration in Steam-Assisted Gravity Drainage Producer Wells
DownloadFall 2023
Sand control screens are necessary for steam-assisted gravity drainage (SAGD) wells drilled into oil sands to prevent sand production. However, the accumulation of mobilized fine particles near the wellbore can result in screen plugging, adversely affecting the well's flow performance. This...

The primary motivation of this research is to investigate the conditions and parameters that influence the formation, stabilization, destruction and reformation of the multi-particle sand arching (bridging) that occurs at the opening of the sand filters to support sand retention. In particular,...
