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

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.
