Role of Asphaltene in Stability of Water-in-oil Model Emulsions: The Effects of Oil Composition and Size of the Aggregates and Droplets
Download2021-03-16
Water-in-oil (W/O) emulsions are the most common type of emulsions handled in petroleum processes. It is thought that the field emulsions are primarily stabilized by asphaltene-resin micelles and several research works have studied the stability mechanisms of asphaltene in crude emulsions....

Mohammad Haftani, Omar Kotb, Phuong H. Nguyen, Chenxi Wang, Mahmoud Salimi, Alireza Nouri
Optimum design of the sand control devices in oil sand reservoirs plays a vital role in minimizing the sand production and increasing the reservoir productivity in Steam-Assisted Gravity Drainage (SAGD) operations. Various sand control testing facilities have been developed to evaluate the...

Rahman Miri, Mohammad Haftani, Alireza Nouri
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...

A Set of Graphical Design criteria for Slotted Liners in SteamAssisted Gravity Drainage Production Wells
Download2018-01-01
Chenxi Wang, Yu Pang, Mahdi Mahmoudi, Mohammad Haftani, Mahmoud Salimi, Vahidoddin Fattahpour, Alireza Nouri
Slotted liners have been widely used in steam-assisted gravity drainage (SAGD) wells owing to their low cost and superior mechanical integrity. Multiple factors affect the performance of slotted liners, such as particle size distribution (PSD) of formation sands, aperture size, slot density,...

Developing a Methodology to Characterize Formation Damage (Pore Plugging) due to Fines Migration in Sand Control Tests
Download2019-01-01
Chenxi Wang, Jesus D. Montero Pallares, Mohammad Haftani, Alireza Nouri
Stand-alone screens (SAS) have been widely used in steam assisted gravity drainage (SAGD) operations. Although many researchers investigated the flow performance of SAS through sand control tests, the formation damage (pore plugging) due to fines migration has not been characterized under...

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...

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...
