Effects of Inherent Fabric Anisotropy and Intermediate Principal Stress on Constitutive Behavior of Uncemented and Cemented Sands
Download2016-01-01
Mojtaba Rahimi, Dave Chan, Alireza Nouri, Rouzbeh Rasouli
Sand response changes with intensity of cementation bonds between sand grains, magnitude of intermediate principal stress and with fabric anisotropy. First a critical state bounding surface plasticity model is presented in this paper. In this constitutive model, the loading surface always...

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...

Environmental risk factors for bacteriological contamination in rural drinking water wells in Samson Cree Nation
Environmental risk factors for bacteriological contamination in rural drinking water wells in Samson Cree Nation
Download2018-01-01
Fraser Mah, Travis Hnidan, Evan Davies, Ania Ulrich
Bacteriological contamination of drinking water wells poses a challenge to many rural areas of First Nations communities in Alberta that rely on wells as the primary drinking water source for large proportions of their populations. Here we reviewed available historical data for the Samson Cree...

Experimental Correlations for the Performance and Aperture Selection of Wire Wrapped Screens in Steam Assisted Gravity Drainage Production Wells
Download2020-08-01
Jesus David Montero Pallares, Chenxi Wang, Mohammad Haftani, Alireza Nouri
Wire-wrapped screens (WWSs) are one of the most-commonly used devices by steam-assisted gravity drainage (SAGD) operators because of the capacity to control plugging and improve flow performance. WWSs offer high open-to-flow area (OFA) (6 to 18%) that allow a high release of fines, hence, less...
