Methodology for Developing Plans for Brownfield Assets to Produce Residual Recoverable Reserves

The proposed methodology addresses the challenges of developing mature oilfields by optimizing the extraction of residual recoverable reserves. Key elements of the approach include a comprehensive analysis of the current well base, advanced forecasting of production decline rates, data validation, and the creation of detailed production profiles.

Economic efficiency is ensured through detailed cost analysis and profitability assessments (PI coefficient), which allow for the ranking of project solutions and the selection of priority drilling sites.

Additionally, innovative technologies such as multilateral drilling, horizontal wells, and hydraulic fracturing are integrated to enhance hydrocarbon recovery and improve profitability.

The methodology has been successfully tested on 141 project well pads, yielding significant results, including:

• Increased extraction of residual reserves,
• Improved economic efficiency, and
• Accelerated project execution.

This flexible and comprehensive approach is adaptable to various geological and operational conditions, ensuring sustainable development of mature fields. Furthermore, it is a completely new approach that has already proven its effectiveness on real assets in Western Siberia. Future advancements include integrating the methodology into digital management platforms and leveraging machine learning for risk assessments and technological optimization.
