About

I am associate professor in reservoir engineering at Department of Geoscience and Petroleum (IGP), NTNU since January 2019. In 2022, I was selected as one of NTNU’s young talents in Outstanding Academic Fellows Programme 4.0 (2022-2026). My research group (including PhD, Postdoc, and master students) perform cutting edge research on numerical and data-driven subsurface reservoir modeling.

I have had the following managerial roles at NTNU:

2022: Project manager in NORHED II: Education and Research within Energy at two Mozambican universities
2021-2022: Head of the Reservoir Engineering and Petrophysics Group
2020-2024: Leader of the CEORS Gemini Centre (strategic collaboration between NTNU and SINTEF on CO2 Enhanced Oil Recovery & Storage)
2019-2022: Study profile manager in Engineering & ICT study program committee (an advisory board for the study program manager)
2017-present: Chairperson, Young Professionals Chairperson, and Faculty advisor at Society of Petroleum Engineers (SPE) Trondheim section.

My background is reservoir engineering:

2015: PhD, Norwegian University of Science and Technology (NTNU), Norway
2009: MEng., University of Calgary (UofC), Canada
2008: MSc., Petroleum University of Technology (PUT), Iran
2006: BSc., Petroleum University of Technology (PUT), Iran

After PhD, I worked (2015-2017) at DNVA (Norwegian Academy of Science and Letters, supported by Equinor) as recipient of a prestigious post-doctoral research scholarship on polymer gel simulation study. It is this academy that awards the Abel prize in mathematics.

I did another postdoc at PoreLab SFF (Norwegian Center of Excellence) on wettability alteration in low-salinity water flooding.

Research

I am specialized in subsurface reservoir modeling, enhanced recovery and fluid flow in porous media, and my current research includes:

CO2 injection for enhanced recovery and subsurface storage
Data-driven reservoir modeling
Production optimization
Field development
Well test analysis (PTA/RTA)
PVT, fluid model development

My research includes participation in the following groups at NTNU:

Leader of the CEORS Gemini center
Science team member of the Reservoir Management and Production Optimization group in BRU21 (Better Resource Utilization in the 21st century)
Research associate at PoreLab SFF (Norwegian Center of Excellence), Microfluidics and field studies (RESEARCH THEME 6)

I have written more than 40 journal and conference papers (selected recent publications below). I have also presented research work in more than 20 national and international conferences since 2008. Some invited presentations include:

Invited talk on CO2 EOR and Storage at Joining Forces seminar, April 2022, Stavanger
Invited talk about Carbon Capture and Storage at NPF digital lunch meeting, February 2022
Invited talk on digitalization at NFiP PhD seminar, November 2018, Stavanger

Teaching

Courses

I completed the NTNU’s 200-hour basic competence program for university pedagogical education in 2020. I am currently teaching masters and PhD courses (complete list below) including reservoir simulation and reservoir fluids (PVT) and flow:

TPG4145- Reservoir Fluids and Flow (2019-)
PG8601- Specialized Reservoir Simulation Models (2020-)
TPG4112- Geomechanics and Flow in Porous Media (2023)
TMR4325- Engineering and ICT, introduction (2019-2022)
TPG4115- Reservoir Property Determination by Core Analysis and Well Testing (2012-2015, 2019-2020)
TPG4117- Unconventional Reservoirs (2012-2014)
TPG4177- Carbonate Reservoir Characterization (2012-2014)

I was also the project manager and lecturer in Teknostart course (for 1st year Engineering students) in both Geoscience and Petroleum (2019) and I&IKT (2020) study programs at NTNU.

Supervision

I have been the main supervisor for 15 master students at NTNU and 3 Erasmus+ exchange students. I have been the main supervisor for 3 PhD candidates:

2022-2025: Jinjie Mao, Advanced Modeling – Optimization Framework for Sustainable Utilization of the Subsurface by CO2 Injection
2021-2024: Markus Hays Nielsen, End-to-end fluid model development- Doctoral Innovation Project in Industry funded by Research Council of Norway and Whitson AS
2019-2022: Cuthbert Shang Wui Ng, Data-driven reservoir modeling

I was also the main supervisor for EU MSCA-IF postdoc on Smart Proxy Models for Reservoir Simulation (H2020-MSCA-2019, project SPM-RS 895406), which was terminated due to COVID19.
