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....

A Novel Sand Control Testing Facility to Evaluate the Impact of Radial Flow Regime on Screen Performance and its Verification
Download2020-05-11
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...

Protocol for Optimal Size Selection of Punched Screen in Steam Assisted Gravity Drainage Operations
Download2020-01-21
Chenxi Wang, Jesus D. Montero Pallares, Mohammad Haftani, Alireza Nouri
Punched screen as a stand-alone screen is gaining more and more popularity in Steam Assisted Gravity Drainage (SAGD) operations. However, the literature contains limited studies for proper aperture size selection and the performance of the punched screen. This paper aims at investigating the...

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...

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...

Smeared Modeling of Hydraulic Fracture Using Partially Coupled Reservoir and Geomechanics Simulators
Download2019-01-01
Morteza Roostaei, Siavash Taghipoor, Alireza Nouri, Vahidoddin Fattahpour, Dave Chan
There are aspects of the hydraulic fracturing process that remain unresolved for weakly consolidated sandstones. These issues include fracture modes and geometries for weak sandstones, and higher-than-expected fracture pressure in some field projects. The development of shear bands and the...

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,...
