Abstract

This paper presents a realistic synthetic case study based on data and materials integrated from public domain research carried out by the authors. The selected geological formation contains an abundance of oil reserves in the Middle East, and is classified among the most economically important. In comparison with on-site well testing operations, the computer-based workflow used in this study does not require to shut in any well or change production. Hence, the oil field production and water injection can be maintained suitably and sustainably. It is proposed to build multi-layered sector models to better capture both overall regional reservoir behavior and local effects between alternating rings of production and injection wells, even between individual multi-lateral wells and in the wellbore vicinity. It is shown that different horizontal variogram range influences phase productivity indices of wells, which may highly impact the accuracy and precision of production forecasts in planning field development, designing well stimulation operations and enhanced recovery processes. The presented case study does not intend to replace any real full field reservoir model, but this can serve for quick feasibility and evaluation studies allowing to improve the workflows used by oil and gas companies faced similar challenges.
