About bp

As a leading global energy company with a presence in over 61 countries, bp is dedicated to delivering energy to the world, today and tomorrow. Across the bp landscape, we’re home to a range of brands across many areas of our industry. For over 100 years, we’ve focused on discovering, developing and producing oil and gas in the nations where we operate. Delivering our strategy sustainably is fundamental to achieving our ambition to be a net zero company by 2050 or sooner. It's an exciting time to join bp. From wellbeing programs to mentorship and career growth opportunities, we aim to ensure you can thrive – in work and in life.

About the role

As a first step, nothing prepares you better for a career with us than an internship. Our internship program provides hands-on, career-specific experience working full-time during the summer. You will work on real projects that deliver tangible benefits and measurable results. At the same time, you will have the opportunity to learn about and help to solve some of the most important issues we face. You will experience genuine teamwork, and work alongside highly qualified and experienced colleagues, while you work on live projects and operations, using the latest equipment and technology.

Global Subsurface Solutions provides technical support to bp’s regional businesses in various areas including reservoir fluid characterization. As specialist reservoir engineers, Complex Fluids practitioners provide technical expertise globally in understanding the fluid properties, the associated risks, and mitigation strategies for our resilient hydrocarbon business and low carbon energy transition. They play a critical role in making sure fluids are properly described to make the business safer and our predictions more reliable. Complex fluids support covers the entire project cycle by planning the fluid sampling and analysis for renewal to modeling the fluid phase behavior for projects and operations. Over the past few years, the complex fluids specialists are also being called on more and more to advise on the fluid implications for CCS and Hydrogen projects.

In this role you will gain:

  • Vital skills in reservoir fluid characterization that are essential to both resilient hydrocarbon and low carbon energy transition.

  • Insights on how reservoir fluids are modelled through Subsurface and Surface in various softwares.

  • Experience of working in a highly experienced Reservoir Engineering team within the Reservoir Performance Prediction and Management (RPPM) Unit.

  • Global exposure to many O&G and CCUS projects.

  • Extended network across P&O, G&LC, I&E, and Regions.

  • Deeper understanding of BP businesses from different perspectives.

  • Exposure to cutting edge research in low carbon transition, like Hydrogen storage.

  • Working relations with various disciplines such as geoscience, engineering, microbiology, production chemistry, etc.

In this role you will:

  • Plan the fluid sampling and surveillance programs.

  • Oversee the fluid analysis in the third-party laboratories and conduct quality check and estimate in-situ reservoir fluid properties from PVT data.

  • Develop equation of state models and table of properties for reservoir dynamic performance prediction, flow assurance, process simulation, and multiphase flow meter configuration.

  • Contribute to the understanding of reservoir connectivity/compartmentalization through PVT data analysis.

  • Simulate reservoir souring to support projects and operations (using SourSimRL software).

  • Participate in Integrated Fluids Reviews (IFR) for Major Projects (Hydrocarbons, CCS and potentially Hydrogen). Inform the fluid risk management by providing fluid analysis results.

  • Support development of complex fluids workflow and practices including fluids database, software applications, and internal tools.

  • All the above are delivered in collaboration with various stakeholders from Subsurface, Production, Wells, Projects, Regional teams, and external vendors.

Successful interns may be considered for a full-time role within our One Subsurface programme upon earning their degree. One Subsurface is our early careers programme designed to create a pipeline of subsurface professionals. Early careers will follow a structured development offer to accelerate the acquisition of foundational technical skills, experience and knowledge, and application in the business world. The programme supports transition from university to discipline professional and provides a framework of ‘non-technical’ skills to support building personal effectiveness skills. Early careers will build their experience through challenging development assignments, grow a toolkit of transferable skills for the future, and have a dedicated network of support to help them succeed.
