40 Years of Trust and Results

Turning the Possible and Probable Into Proved


Whether you decide to dip your toe, or jump in completely, there is risk associated with any energy project. In natural gas and oil exploration there’s no shortage of those who can make educated guesses about potential and assert predictions on paper.

But verifying, extracting, storing and transporting is how that potential is harnessed and monetized.

At Mohajir Energy Advisors, we’ve been assessing the possible and probable, and turning it into proved for over 40 years. Well before any capital is deployed or derricks are raised, we apply technical expertise and build financial models that are tempered with refined common sense.

We care deeply about the success of our clients and we hold each other to high standards when it comes to the work, value and returns we deliver.
