Who are you?

Charignon Isabelle, Master's Students, Electrical and Computer Engineering

Who is your employer?

Schlumberger SRPC
​Clamart, France

How did you learn about your internship?

I have first learned about Schlumberger through recruiting events organized by Schlumberger in partnership with my French engineering school SUPELEC. I had also talked with a friend from Gerogia Tech who did a 6-month internship last year in SRPC. He strongly recommended this position to me. Therefore I applied online by posting my resume on the Schlumberger website.

What was the application process like?

I submitted online my resume. Then I was contacted by a HR for planning a first phone interview with her. Then I had another phone interview with my manager and his manager. All the interviews were phone interviews since I was in Atlanta and the position was in France.

What were your major tasks or projects at this internship?

The objective of the internship was to design and test a module ( sensor + electronic board ) for water fraction measurement in down hole well environment. The study includes mechanical simulations of the sensor, development of electronic board and preliminary evaluation via flow loop test. So during my internship, I had three main goals. The first one was to study and simulate the sensor to define its geometry. For that I used ANSYS software and finite element method. When the design of the sensor was fixed we launched its fabrication. This first step of my internship took me approximately 1 month. The second goal was to design an electronic board for computing the water fraction measurement. It included definition of the electronics architecture and design of the electronic board (detailed schematics, placing and routing). While the electronic board was being manufactured, I started to develop a part of the firmware on the micro-controller. This second step took me approximately 3 months. The last goal of my internship was validation tests. It included tests of the electronic board, tests of pre-prototype sensors and flow loop tests. This last step took me approximately 2 months.

Do you have any recommendations for Georgia Tech students looking to intern in the same company or country?

There are some requirements: - Speaking French is not required but highly recommended to work easily with other people in Schlumberger. -Speaking English is required. -Having a broad background in engineering is required and especially in mechanical engineering and electrical engineering. -Knowing how to program micro-controllers is preferred.

Where did you live? Did you find accomodations independently or with your company's help?

I was renting an apartment in Paris for 6 months. I found it independently, without the help of Schlumberger.

How has this internship influenced your career path?

I was thinking of starting my career as an electrical engineer but I was not sure if I would like this position or not. That is why I did a six-month internship in Schlumberger. Through this experience I was expecting to learn lot of things. My two main personal learning objectives were to discover the inner workings of how a successful company works and to develop new skills in electrical engineering.

If paid, did the company you worked for pay you enough to live off of your salary or stipend, or did you have to supplement your income with personal funds?

The company did not pay me enough to cover all my expenses. The salary was covering only the housing, phone and internet. I had to supplement my income with person funds.
