Siavash Taghipoor, Morteza Roostaei, Arian Velayati, Atena Sharbatian, Dave Chan, Alireza Nouri
This paper presents a numerical investigation of hydraulic fracturing in oil sands during cold water injection by considering the aspects of both geomechanics and reservoir fluid flow. According to previous studies, the low shear strengths of unconsolidated or weakly consolidated sandstone...

Numerical Modeling of Hydraulic Fracturing in Cohesionless Sand: Validation Against Laboratory Experiments
Download2015-01-01
Slavash Taghipoor, Alireza Nouri, Dave Chan
Summary In this paper, a new hydraulic-fracturing model is introduced for cohesionless sand, which is also applicable to weak sandstone formations with high permeability and low shear strength. Phenomena such as shear-band development and shear-enhanced permeability are of paramount importance...

Mahshid Jafar Pour, Alireza Nouri, Dave Chan
This paper presents a numerical model with a new approach for analyzing the propagation of pressure waves in porous media and investigates the dynamic response of sand in relation to the attributes of pore pressure pulses. There are various instances in which dynamic phenomena can have a...

Morteza Roostaei, Alireza Nouri, Vahidoddin Fattahpour, Dave Chan
A central issue in hydraulic fracturing treatment in petroleum wells is the transport of proppant particles by the injection fluid. In this paper, we present an innovative proppant transport model in a fixed rectangular- and elliptic-shaped slots. The proposed model is an improvement to the...

Oil sands process affected water sourced Trichoderma harzianum demonstrates capacity for mycoremediation of naphthenic acid fraction compounds
Oil sands process affected water sourced Trichoderma harzianum demonstrates capacity for mycoremediation of naphthenic acid fraction compounds

Sarah M. Miles, Evelyn Asiedu, Amy-lynne Balaberda, Ania C. Ulrich
Development of Alberta’s oil sands requires large volumes of water, leading to the abundance of oil sands process affected water (OSPW) that must be remediated prior to discharge or reuse. OSPW contains a variety of dissolved organic compounds, however naphthenic acids (NAs) have been found to...

Operating a mobile photo radar enforcement program: A framework for site selection, resource allocation, scheduling, and evaluation
Download2019-11-07
Kim, A. M., Wang, X., El-Basyouny, K., Fu, Q.
This paper introduces a systematic, data-driven framework by which to operate a mobile photo radar enforcement (MPRE) program, consisting broadly of site choice, enforcement resource allocation and scheduling, and evaluation. The overall goal is provide a framework for operating an MPRE program...

Potential syntrophic associations in anaerobic naphthenic acids biodegrading consortia inferred with microbial interactome networks
Potential syntrophic associations in anaerobic naphthenic acids biodegrading consortia inferred with microbial interactome networks
Download2020-01-01
Xiaofei Lv, Bin Ma, Korris Lee, Ania Ulrich
Naphthenic acids (NAs) can be syntrophically metabolized by indigenous microbial communities in pristine sediments beneath oil sands tailings ponds. Syntrophy is an essential determinant of the microbial interactome, however, the interactome network in anaerobic NAs-degrading consortia has not...

A. Bahadori, M. Mahmoudi, A. Nouri
Heavy-oil development is becoming increasingly important because of the continuous decline in conventional-oil production. For heavy-oil reservoirs, the oil viscosity usually varies dramatically during production processes such as in thermal processes. When producing heavy oil, the high viscosity...

Predictive model for construction labour productivity using hybrid feature selection and principal component analysis
Download2022-01-01
Ebrahimi, Sara, Kazerooni, Matin, Sumati, Vuppuluri, Fayek, Aminah Robinson
Construction labour productivity (CLP) is affected by numerous variables made up of subjective and objective factors. Thus, CLP modelling and prediction are a complex task, leading to high computational cost and the risk of overfitting of data. This paper proposes a predictive model for CLP by...

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...
