This paper presents a fast turnaround Integrated Reservoir Modelling (IRM) workflow for a deep water turbidite field. It is based on a static and dynamic Experiments of Design (DoE or ED) workflow that is used as a toolkit for uncertainty management. The case study shown here emphasizes the application of this "Multi Scenario Approach" methodology for field specific decisions such as short and mid-term reservoir management optimization and infill development opportunities, including impact of key subsurface uncertainties on these decisions.

The objectives of Integrated Reservoir Modelling workflow presented here are:

  • To create fully integrated models or multiple scenarios that provide realistic ranges of forecasts, e.g. geologically sound, to underpin development and operational decisions without anchoring to a single base case; and

  • To shorten modelling life cycle to achieve faster project delivery and allow for uncertainty workflows as proposed in this paper. There are many decisions that are dependent on model forecasts such as identifying infill well target locations and number of wells at the project level, project phasing to extend production plateau, and to identify and mitigate key projects technical risks
