Addressing Understanding compartmentalisation uncertainty using geologically constrained interactive fault extension workflows


Presenter: Dan Hemingway

Faults have the potential to compartmentalise reservoirs and have significant impact on sweep prediction and, ultimately, reservoir development cost. Compartmentalisation uncertainty analysis should form a routine part of quality assurance workflows through the entire reservoir development lifecycle.



In the Autumn edition of our Ava Structure Webinar Series, we take another look at the Ameland Field, NL using a selection of new techniques and workflows to demonstrate a novel approach to addressing structural compartmentalisation uncertainty. Predictive fault tip extension workflows will be geologically calibrated and used to generate P10, P50 and P90 structural cases, allowing for the full integration of compartmentalisation uncertainty to conventional reservoir risk analysis workflows. We will take a look at identifying subsurface relay structures and conditioning fault extension trajectories using dynamic regression and data-derived interactive extension methods to honour structural complexities that would otherwise be ignored.
