Perform sensitivity studies and uncertainty analysis, and generate probabilistic forecasts.


Industry challenges and technological value

Final investment decisions, either for greenfields development or brownfields rejuvenation, are an exercise of confidence in realizing good returns on your investment. Understanding the upside and downside risks means knowing your subsurface uncertainties and their impact on hydrocarbon volumes/recovery. At the same time, this has implications for surface facilities operating envelope and economics. Integration across all disciplines is key for efficiency gains. 

The Petrel platform and its innovative processes, such as Geoscreening, in tandem with the ECLIPSE and INTERSECT reservoir simulators, enables better decisions and enhanced understanding of risks—all in a single, shared-earth environment. By capturing static and dynamic aspects of subsurface uncertainty, testing various well locations considering uncertainty risk maps, allows for better optimization of surface constraints. Ultimately it enables more confident risk-adjusted decisions. 


Managing uncertainty, optimizing the production system, and assessing economics span very different domains and products. The Petrel platform’s unique integration and ability to link and manage from a single interface all domains provides your asset team with distinct advantages in work productivity. The intuitive uncertainty and optimization process dialog in the Petrel platform guides the setup of ample studies/runs.

These technologies unlock multifaceted features that assist in managing the most challenging field-development processes:
