The oil and gas industry develops projects in different regions of the world. This creates the need for professionals capable of participating in international teams, sharing technical knowledge and working with tools used in different countries.

International roles in oil and gas: opportunities for technology profiles

For those who wish to build a career with global reach, there are opportunities related to reservoir engineering, geosciences, simulation and technology development.

Oil projects need specialized knowledge that can be transferred between different regions. For example, the principles used to simulate a reservoir can be applied in different countries, although each geological formation has particular characteristics. In addition, technology companies offer solutions used by energy organizations in different markets. Companies such as SLB, Rock Flow Dynamics and Computer Modelling Group develop specialized tools for the industry.

This situation favors the mobility of certain technical profiles and collaboration between teams located in different places. However, international hiring depends on professional requirements, experience, languages and immigration conditions.

Main international roles

Reservoir engineering and simulation

The reservoir engineers participate in the evaluation, development and optimization of reservoirs. One of the degree programs most closely related to this work is the Petroleum Engineering. Those who specialize in simulation can work with tools such as ECLIPSE by SLB, tNavigator by Rock Flow Dynamics and the CMG simulators. Their knowledge is useful in projects that need to analyze geological uncertainties, production plans and recovery alternatives.

Geoscience and consulting

Professionals with degrees in Geology, Geophysics and specialists in subsurface modeling can participate in international exploration and development projects. Proficiency with platforms such as Petrel by SLB is a relevant technical skill for certain roles. Specialized consulting firms may also hire professionals to conduct studies of different energy assets.

Software development and support

Technology provider companies need software developers, specialists in numerical methods, implementation consultants and support engineers. These roles can combine programming knowledge with experience in energy processes. The Rock Flow Dynamics tNavigator platform is an example of specialized technology that requires development, maintenance and technical support. For example, a professional with a degree in Computer Engineering can specialize in developing simulation tools, while a petroleum engineer can focus on implementing technical solutions.

Skills needed to work internationally

Technical English is an important skill because it facilitates communication with teams, clients and providers. It also makes it possible to understand specialized documentation for platforms such as Petrel and tNavigator.

Also relevant are report writing, the ability to present results and knowledge of specialized software tools. Training in Data Science can contribute to developing skills to interpret and communicate technical information.

In advanced positions, experience solving real problems, autonomy and the ability to collaborate with specialists from different disciplines are valued.

Additional training and certifications can be useful, although they do not replace each employer's specific requirements.

International opportunities in oil and gas

Opportunities for technology professionals in the energy sector can be seen in specific openings from international companies. These companies look for specialists in simulation, engineering, programming, data analysis and scientific software development.

Brazil: scientific software development with Python

In Brazil, Halliburton, through its Landmark division, published an opening for scientific software developers specialized in Python. The position, advertised as remote in Brazil, includes programming, data analysis, geospatial visualization and application development for the energy industry. Required knowledge includes Python, NumPy, Pandas, JavaScript and English.

Mexico: reservoir engineering and simulation

In Mexico, SLB published a search for reservoir engineers specialized in simulation. The position involves reservoir studies, production models and planning the development of oil fields. The company requires experience with tools such as Petrel, ECLIPSE or INTERSECT, as well as advanced English.

Canada: reservoir consulting and simulation

In Canada, Computer Modelling Group (CMG) offers a hands-on training position in reservoir simulation in Calgary. Its responsibilities include assisting international clients, participating in oil and gas recovery studies and providing training on specialized software. The posting requires having legal authorization to work in Canada.

Norway: software engineering for petroleum simulation

In Norway, Halliburton announced a software engineering position for its reservoir center of excellence in Oslo. The position combines knowledge of geosciences, reservoir modeling and Python programming to develop applications used in simulations and production decisions.

Serbia: international consulting with tNavigator

In Serbia, Rock Flow Dynamics is seeking reservoir engineers with experience in integrated modeling to work with tNavigator. Tasks include building reservoir models, solving clients' technical problems and providing training. The company requires English proficiency and offers assistance with residency and work procedures in Serbia.

Saudi Arabia: advanced reservoir simulation

In Saudi Arabia, Aramco posted an international call for reservoir simulation specialists. The position includes model calibration, compositional simulation, fracture studies and optimization of hydrocarbon recovery. It is aimed at experienced professionals and requires at least fifteen years of experience in simulation.

Venezuela: simulation and hydrocarbon recovery

In Venezuela, SLB published a search for reservoir engineers in Maturín. The position requires developing dynamic models, analyzing production data and evaluating hydrocarbon recovery alternatives. The required knowledge includes Petrel, ECLIPSE, CMG and intermediate or advanced English.

Guyana: training young professionals in energy

In Guyana, Halliburton launched the Development Excellence Engineer Program (DEEP) 2027, aimed at recent graduates of scientific and technological degrees. It combines hands-on experience, mentoring and training in technical and leadership skills. It is intended for professionals with up to two years since graduation who currently reside in Guyana.

These examples show that the oil industry needs both reservoir specialists and professionals capable of developing software tools, interpreting data and working with international clients.

Among the related degrees are Petroleum Engineering, Computer Engineering, Geology and Data Science.

International opportunities do not necessarily require performing operational tasks in oil wells. There are also positions in programming, simulation, research, technical support and consult

How to prepare for a global career

To access international opportunities, it is advisable to combine academic training with technical skills demanded by companies. Degrees such as Petroleum Engineering, Computer Engineering and Data Science allow you to develop different specializations within the energy sector.

A practical way to gain experience is to work with real oil data. For example, the Norwegian company Equinor offers open data from the Volve field, which can be used to study production, analyze wells and develop simulation projects.

It is also useful to learn specialized tools. CMG offers training in reservoir simulation, while SLB has tools that integrate Python with Petrel software to automate processes and analyze geological information.

Technical English can also be decisive. For example, SLB requires advanced English for certain reservoir engineering positions, along with simulation experience and knowledge of specialized software.

To build an international profile, simply accumulating courses is not enough. It's important to develop your own projects, document the results and demonstrate how knowledge is applied to solve real industry problems.
