Big Loop

A Collaborative Approach to Calibrating Subsurface Models for Reliable Production Concept Design and Forecasting.

Big Loop™ is an automated, ensemble based, stochastic workflow that tightly integrates the static and dynamic domains, ensuring that all the important reservoir uncertainties are captured and used as input parameters to the reservoir simulator. By adjusting these input parameters, multiple realisations of the dynamic model, constrained by production history, are created via an iterative loop. The result is a calibrated flow model that is consistent with the underlying geology. The workflow is easy to update and allows for more time spent on analyzing the results and building a common understanding of the reservoir.BigLoop.png
