With the dearth of easy oil in the industry, the importance of consistency in quantifying uncertainties and assessing their impact on investment decisions have become very crucial in management decisions. This has seen the stocks of both experimental design and response surface techniques in the E&P industry rise significantly as an alternative to the more traditional uncertainty analysis.Whilst there are papers describing experimental design workflows and the different methods of generating response surface models for reservoir simulation studies, there is also a growing need to share practical examples of the lessons learned in constructing experimental designs and using response surface models to interrogate the experimental design outcomes.After extensively applying these concepts for over 18 months in identifying the major sub-surface uncertainties, explaining observed production performance and in prescribing additional development options for fifteen reservoirs situated in four different fields that are at different stages of maturation, it has been possible to capture many useful lessons. These lessons will both strengthen the benefits and ease the pains of applying these concepts in reservoir simulation studies. |
