Chenxi Wang, Mohammad Haftani, Jesus David Montero Pallares, Alireza Nouri
Slotted liners are widely used in steam-assisted gravity drainage (SAGD) wells to control sand production and sustain wellbore productivity. The slotted liner can provide desirable performance when appropriately designed. A literature review indicates a limited number of studies that offer design...

Sand production from a poorly consolidated reservoir could give rise to some severe problems during production. Holding the load bearing solids in place is the main goal of any sand control technique. The only sand control techniques that have found applications in steam assisted gravity drainage...

Yujia Guo, Morteza Roostaei, Alireza Nouri, Vahiddodin Fattahpour, Mahdi Mahmoudi, Heeseok Jung
Steam Assisted Gravity Drainage (SAGD) is the primary thermal recovery technology currently employed to extract heavy oil and high-viscosity bitumen from Alberta oil sands. In the nearwellbore region, the initial stresses are nearly zero, and as the SAGD chamber grows, the stresses tend to...

Emulsification and Emulsion Flow in Thermal Recovery Operations with a Focus on SAGD Operations A Critical Review
Download2019-11-11
Steam assisted gravity drainage (SAGD) is a thermal hydrocarbon recovery method by which extra-heavy oil is produced through steam injection and bitumen heating. The presence of emulsions in the produced fluid has been detected from the very beginning of SAGD deployment. However, this...
