“…Thanks to the domains integration it is possible to identify possible constraints, potential deviations and flow assurance at any parts of entire production system. Integration ensures that all set boundary conditions are honored at all times [2]. This solution can be applied for daily production optimization as well as shortand long-term field development planning.…”

Nowadays, because of the smaller and smaller chances of discovering new hydrocarbon deposits with abundant resources as well as significant technological advance, the proper strategy of reservoir management connected with simultaneous optimization of its production parameters is the key element in the process of development the most economically advantageous variant of reservoir management and field development. In Polish Oil and Gas Company, the project called as "Digital reservoir" based on the interactive IAM platform was initiated, thanks to which the work of all upstream segments was integrated, starting from geophysics, geology through reservoir engineering, production engineering, process engineering ending with the economic model that allows for verification of the economic efficiency of the investment. This paper presents the methodology of integration all of the above elements and the results of the IAM system implementation with further production forecasts, on the example of selected natural gas reservoirs in the Polish Lowlands being PGNiG S.A. assets.

ADNOC has embarked on the second phase of its ambitious integrated capacity model (ICM) project with the overall aim to optimise its fluid production portfolio from the well level to the processing facilities. A key feature of the new software tool is the ability to track and predict fluid properties over time across the entire production network, comprising thousands of wells and a myriad of pipelines. The reservoir fluid composition is assigned at well level for each producing reservoir. The compositional tracking over time is straightforward for many wells, but complicating factors do arise, such as Lateral compositional variation related to complex reservoir charging history Vertical compositional gradients, especially for near-critical fluids The presence of initial and secondary gas caps, resulting in gas coning Injection of miscible gas for enhanced oil recovery The fluid systems range from medium-API oil to gas condensates and the key chemical components vary as follows: C1 [5-80%], CO2 [0.5-8%], and H2S [0-35%]. Mixing of pressurized fluids with different compositions at various junctions in the network requires a robust thermodynamics model to capture the associated variation in fluid properties, particularly density and viscosity as a function of pressure and temperature. We demonstrate that it is possible to constrain one unified equation of state applicable to all fluids, as long as the fluid systems used for the tuning span the entire range of compositions observed. Mixing of fluid streams is computationally much simpler if each stream is made up of the same components (although in different amounts) with the same component properties. On average, the predicted fluid density is within 1% of the measured value from a multi-stage separator test.

Reservoir management guidelines are an enabler of, production sustainability, assurance to reservoir health and high ultimate recovery. Monitoring the compliance of the field production against the set of reservoir management guidelines is one of the key processes for ADNOC, being a governing body of major U.A.E. hydrocarbon producing fields. With the business need to ramp up production, field maturation, and the associated operational challenges, it is critical for ADNOC to effectively monitor and regulate its field production plans to assure the long-term production sustainability. In this regard, ADNOC has developed a robust framework that is implemented through an automated analytics platform that enables different ADNOC technical teams to effectively monitor and report the compliance status of each hydrocarbon barrel from produced from ADNOC assets. The paper highlights the features of the workflow implemented, the management of change strategy and the business value created. The automated process allows the consolidation of a variety of well, reservoir and field-level data. The analytical platform enables integrated analysis, KPI calculation and interactive visualization. The framework assesses the compliance based on three governing parameters: well technical rate, gas-oil ratio (GOR), and bottom hole flowing pressure. The compliance analysis is carried out on a monthly basis where the monthly back allocated production data for each well is compared with the set of operating guidelines in an automated data analytics and visualization environment. A pragmatic compliance tolerance is considered in the calculations to accommodate the measurement inaccuracies, as well as the operational limitations while allowing flexibility to exclude nonconformity with valid reasons. The overall process is governed through an automated business process management (BPM) platform, which seamlessly regulates the predefined subroutines among different stakeholders to report and track different corrective actions in a timely manner. The framework implementation has strengthened the overall compliance governance process; and has been instrumental to properly manage asset production capacity in a systematic manner. This has subsequently enabled the preparation of a prompt action plan and has improved the operating efficiency of more than 3% within the first six months of implementation, through restoring, compensating and increasing the effective capacity of overall ADNOC Production. The approach has demonstrated great value both in terms of process alignment, as well as from the production assurance standpoint at a country level, and allows the organization to have an established system, which provides: Consistent compliance monitoring standardsMinimal subjectivityComplete process governanceQuick turnaround timeAuditable history The aim of this paper is to publish a stepwise guide for any operators who might be interested to adopt and implement a similar approach to assure the long-term production sustainability and health of their assets.
