The availability of accurate production volumes, at the well level and throughout the production network, is fundamental to the workflows that target the optimization of the economic potential of the reservoir. Without an accurate understanding of production volumes, the company's field development and operational decisions may not support the maximum economic value of the reservoir and can undermine the accuracy of the reserves estimates.

With current Digital Oilfield technology it is possible to measure production volumes at the well level and at intermediate outlets of the production facilities. However, for many fields this isn't a cost effective solution. Building non-parametric (Artificial Intelligence) production rate models based on pressure and temperature measurements has proven to be a valid and cost effective solution.

Several processes are necessary to measure and validate oil production at the well level as follows:

  • Virtual Rate Measurement (VRM): ensuring accuracy of the volumes at the well level.

  • Back Allocation: focussing on accuracy of the volumes at outlets of the facilities. To minimize the error in the volumetric measurements at both ends of the production network, both processes should be reconciled.

  • The reconciliation procedure allows the comparison of the data coming from two different sources. By using this procedure, engineers can detect discrepancies that affect future decisions.

The sum of all these processes working together in a workflow is defined as "Production Performance Monitoring" (PPM).

The objective of this paper is to provide recommendations on how the PPM process should be properly implemented as an automated workflow to improve well productivity as well as to standardize process and data management. To fulfill this objective, the paper will address the following topics: brief introduction of current work practice, processes and workflows descriptions, technology available, real time environment, automated workflow application recommendation and potential benefits.
