About Us

Primera Resources LTD


Primera Resources is a bespoke service provider offering in-depth knowledge and solutions to address our client’s needs and add value to upstream exploration and production workflows. Our high-end workflows offer a unique perspective by integrating static and dynamic reservoir modeling with uncertainty analysis, reserves reporting and reservoir management. We offer solutions focused on identifying well targets and confidently forecasting production in conventional and unconventional studies.

We are a diverse, forward-thinking, group of people with experience in a wide range of upstream disciplines and in different commercial and open source reservoir simulators. We focus on supporting our clients in defining the most optimum reservoir exploitation scheme using fit-for-purpose tools and techniques.

Our solutions incorporate classical reservoir modelling and material balance, well tests analysis of pressure transients and nodal analysis, dynamic reservoir modelling and history matching, reservoir Integrated field development optimisation and economics.
