“…As the natural pressure that once facilitated the flow of hydrocarbons decreases (primary recovery), operators encounter issues such as increased water production, reduced oil recovery rates, and the risk of reservoir coning or gas and water breakthroughs. Moreover, mature reservoirs often exhibit changes in fluid properties over time that can include increased oil viscosity, varying gas-to-oil ratios (GOR), and changes in rock and fluid interaction, as well as a multitude of operational challenges, such as blockages in productive layers, liquid accumulation, and sand production [1][2][3].…”

This study provides insights into the experience gained from the investigation of the dynamic behavior of a mature sour hydrocarbon reservoir modeling under an acid gas re-injection process production strategy. The primary objective was to analyze and evaluate the production behavior of proposed injection zones by assessing various injection scenarios and obtaining oil production over time. To achieve that, a workflow was developed to prioritize potential injection areas, select the optimal wells, determine the optimal operational parameters and optimize a pilot application design based on expected performance. Within this framework, the study encompasses diverse acid gas injection schemes on a pilot scale approach, including acid gas combined with waterflooding. The outcome of this analysis will eventually lead to the identification of the most promising and highest-performing injection scheme, elucidating the optimal range of operating parameters. This optimal combination forms the basis for the economic analysis of the venture and the subsequent detailed design of a full-scale application, where real-world implementation will validate the projected results.

Mature fields have been playing a significant role in the oil and gas realm recently, and redevelopment and optimization efforts are being made globally to prolong the lifetime of these resources. The aim of this study is to showcase the benefits of hydrocarbon reservoir modelling, with a special focus on various aspects of Petrel workflows. This article is a direct continuation of Nemes et al. (2021), which described the Phase 1 geomodel of the same field described in this study. The Phase 2 geomodel – the scope of the current article – is based on a significantly more complete, more detailed, and fundamentally rebuilt dataset compared to Phase 1. The seismic and petrophysical interpretations were updated, and additional data sources were incorporated into the analysis. The geomodel was created in Schlumberger's Petrel software, and during the building of it, a comprehensive 800-plus-step, full-cycle, automated workflow was outlined. The created workflow makes the model update faster by a minimum of five times, makes it more transparent and decreases the risk of human error. The created workflow describes the entire geomodelling process from data loading, via surface adjustments, structural modelling, and property modelling, to a closing of the loop with volumetric calculation. The whole workflow can be rerun easily, and beside the updates made to the geomodel, a full range of quality-check supporting calculations and visualizations were created in order to provide the user with full control. The geomodel showcased here is a key building block of the ongoing and planned development and redevelopment activities in the field, serves as a tool for well and workover planning, water injection system adjustments and a direct input to dynamic simulation, and also provides direct inputs to the documentation of an updated field development plan.
