Belltree Oil & Gas Consulting was established over 10 years ago. During that time, we have developed a reputation for delivering high-quality, commercially-focused technical projects. Our international client base includes E&P operators, Oil & Gas Regulators and Upstream Investment Funds of all sizes, from start-ups to super-majors. Our experience covers the globe, with a strong focus on Africa, Europe and the Middle-East.

At Belltree we believe that it is our role to uncover, quantify and communicate value in a client’s asset portfolio. We achieve this through three key strengths: Personnel, Unique Services and Partners.


Belltree is a bespoke business that typically consults at Asset Manager to Company Board level. Our staff are motivated, fully qualified and able to communicate technical findings accurately and succinctly across all formats. Belltree’s clients benefit from dealing with our most senior staff, who are highly competent in project management, execution and quality assurance.

In addition to offering ‘classical’ subsurface engineering & geoscience services, Belltree has substantial expertise in a number of innovative, value-adding workflows:

  • Field Performance Benchmarking with bMark™
  • Locate The Remaining Oil (LTRO)
  • Advanced Reservoir Simulation

These workflows deliver value and technical insight that goes above and beyond the traditional subsurface consultant capability. Please see our Technical Services and Benchmarking Services pages for more details.
