An Adapted Uncertainty Management Methodology and Tool for Fast-Track Approaches: Light-Up

Light-Up (for Light Uncertainty Process) is part of TOTAL’s in-house tools for uncertainty management. Light-Up provides (1) the assessment of the probabilized HIIP distribution and (2) the methodology and tool to build “tailor-made” models that feed fluid flow simulation for reserves evaluation with or without dynamic uncertainties. Because the uncertainty workflow of Light-Up is pragmatic and fast, Light-Up has been used for several years on a large panel of TOTAL operational cases. The uncertainty workflow which includes Light-Up, composed of 4 main steps, constitutes an integrated workflow.
