Welcome to the 10th Annual Reserves Estimation Unconventionals 2020 Summit


With investor confidence in jeopardy, and future investment at risk, it’s never been more important for operators to demonstrate they can be relied upon in the effective estimation, forecasting and development of their unconventional reserves. But the technical, operational and practical difficulties involved in doing that make this a complex challenge.


Fortunately Reserves Estimation Unconventionals (REU) has the answers. REU has proved to be the industry’s best opportunity for reservoir engineers and corporate reserves managers to find the most proven and practical tools to improve field development decision-making and ensuring reserves reporting and production forecasting meets the expectations of partners, owners, investors and regulators.


Now in its 10th year, REU has established a reputation as the go-to destination for unconventional reserves professionals to get access to the most advanced modeling techniques successfully being applied today to allow improved decision making and more reliable approaches to the estimation, forecasting and reporting of unconventional reserves.
