Interview with research talents

Shivangi GuptaShivangi Gupta

Shivangi’s background
I have a background in Chemical Engineering. I finished my bachelor’s degree in 2013 in Chemical Engineering from Institute of Technology and Management in India. In 2014, I moved to Denmark to pursue a master’s degree in Chemical and Biochemical Engineering at the Technical University of Denmark. During my master’s thesis, I worked with the Danish coating company, Hempel A/S, on long-term durability of silicone coatings for biofouling protection of ships. Just after my graduation, I started working as a research assistant at CERE, Center for Energy Resource Engineering at DTU, on the topic Under Deposit Corrosion in the Oil and Gas Industry. Later I moved to the Mechanical Engineering department at DTU, where I work as a research assistant on oil and gas corrosion.

Present your project
I am currently working on the project: Exploring x-ray tomography methods for corrosion scale characterization: In situ and ex-situ. The idea behind this project is to explore the possibilities for corrosion and scale studies using x-ray tomography as a non-destructive characterization method for both ex-situ and in-situ analysis. The project aims to explore in detail the 3D imaging possibilities using x-ray specifically for scales from for example production wells, and methodology for image analysis for calculating phase content and porosity levels.

What do you expect the major challenges in your area of study will be?
The main challenge in this project is corrosion cell design for in-situ corrosion experiments. Since the space inside the x-ray tomography machine (the ZEISS Xradia 410 Versa) is very limited, it is challenging to have polarized corrosion cell inside the machine with running solution. In addition, the corrosion cell is made of flexible polyamide tube and there is a possibility of leakage if the cell runs for longer than expected. Therefore we need to limit the corrosion time.

How do you plan to contribute in solving these problems?
During my research project at CERE, I gained a detailed understanding of different types of corrosion associated with the oil and gas industry. Based on this knowledge, I contribute in solving corrosion problems related to localized corrosion in sweet and sour conditions. During my master’s thesis and other research projects at DTU, I have gained hands-on expertise on laboratory practices, for example by working with sample analysis through optical profilometer, scanning electron microscope, 3-D microscope and x-ray diffraction technique. I am currently implementing some of these techniques in my present project, which leads to an understanding of importance of systematic and detailed work procedures as well as their accurate implementation.

What are your expectations for your future career?
I would like to continue my research work in the oil and gas field. I hope to apply some of my given solutions in the oil and gas industry.
