Initiating a Digital Oilfield Operating System on Brage field

Abstract

Uncertainty quantification has become an increasingly important request in the decision-making process for targeting infill drilling. Serious weaknesses in current reservoir models can be directly attributed to the lack of proper uncertainty handling. In a mature field as the Brage oil field in the northern part of the North Sea, east of the Oseberg field, where there are many long horizontal wells, uncertainty in well markers and well paths have a tremendous impact on the structural uncertainty (+/-10m). These variations on their own can either create or kill infill drilling targets. A stochastic workflow for dealing with uncertainty on horizontal well trajectories has been derived for a consistent updating of velocity and depth models. Such an automated stochastic workflow is an example of a Digital oilfield operation system (DOOS).
