... procedures may yield largely suboptimal decisions. In this work, we present a comprehensive outline for model-based life-cycle production optimization problems, establishing guidelines to make the process less subjective. Based on several applications and a literature review, we established a consistent...

... studies commonly include uncertainty quantifications, which is performed by simulating multiple geological realizations. For that, the use of fine-scale models can be computationally prohibitive and this requires a proper procedure to upscale the coarse-scale simulation models in multiple realizations...

We describe a systematic approach for uncertainty quantification that combines reservoir simulation and emulation techniques within a coherent Bayesian framework for uncertainty quantification. Our systematic procedure is an alternative and more...

... and a map is generated by averaging the corresponding layers. Although this seems to be a fair practice, here we show that this procedure can present some drawbacks and propose a new approach to ensure a proper data comparison. The first step of the proposed procedure follows the traditional sequence where...

Two history-matching procedures evaluate the impact of the additional objective functions, based...

... Abstract The paper illustrates systems and procedures recently adopted in Italy for the collection and recording of relevant drilling data, in the light of the requirements of Directive 2013/30/EU, elaborated and enforced following the 2010 Deepwater Horizon disaster. Thanks to the increased...

Meanwhile, this approach can save over 60% of the total computing time compared with the normal procedure, and this helps significantly to achieve a rapid and effective seismic history matching and better define uncertainty with a larger number of realisations.
