Model-based reservoir management in 3 stages

The objective of this work is to present a new practical methodology to manage petroleum fields considering three stages (life-cycle, short-term and real-time) that can run simultaneously in parallel with different model fidelities and characteristics. The model-based field management process follows the general methodology proposed by Schiozer et al. (2019) with four activities: (1) fit-for-purpose models construction, (2) data assimilation for uncertainty reduction, (3) life-cycle production optimization and (4) short-term optimization for real-time implementation.  This work presents a novel procedure to integrate three different stages for production optimization that can run in parallel, allowing the integration of life-cycle and real-time solutions. The methodology (1) allows the use of complex reservoir simulation models from the life-cycle production strategy optimization, (2) gives special attention to short-term control parameters improving the quality of the short-term solution, and (3) guides real-time implementation, so it can be the basis to a digital field management.
