This Green Field was commissioned and put on production few years ago and subsequently within a few months Miscible Hydrocarbon Gas injection was started on a Field scale. It is a modern Digital Oil Field having two artificial islands built to drill all its field development wells with advanced completions such as ICV, ICD and Permanent Downhole Gauges in all Oil Producer Wells with automated multi-phase flow metering (MPFM). This paper will describe the utilization of real-time data for better and efficient Field/Wells Monitoring along with quick and smart reservoir management decision-making & improved reservoir characterization. Real-time Dashboards (some of these were published last year, [1]) are utilized for robust screening of wells as per predefined rules and alerting Engineers for any wells, which are close to violating any of the Reservoir Management Guidelines, after QC and verification timely decisions, are made to avoid those violations. These Reservoir Management Guidelines for wells BHP & WHP are taken from Fluid Model (i.e. Equation of State) since the Field has a challenging considerable vertical compositional gradient for each of its reservoirs. The Guidelines are accordingly adjusted whenever a new verified information from PLT or PVT is available. Inter-well Gas Tracers Project implementation on Field scale is ongoing, where Tracers will be injected in all Gas Injection Wells/Strings to improve Reservoirs surveillance, Reservoirs understanding, Gas Injection Management, future wells locations and completion strategy etc. Real-time MPFM Flow Tests & Permanent Downhole Gauges Pressure data is utilized for Real-time Pressure Transient Analysis (PTA) and well shut in time for PBU is therefore optimized. Moreover, All Field/well Shut Down duration opportunities are also utilized for real-time Pressure Build-up (PBU) analysis & recording WHCIP & BHCIP surveys for Oil Producer wells and therefore considerable cost of running Memory gauges and intervention operations is saved. This paper shows examples of PTA data interpretation through real time data that improved decision-making and optimize the performance of each well. The benefits of implementing a digital oil field philosophy for improved decision making in order to maximize oil recovery in a challenging enhanced oil recovery offshore project is also discussed. Successful & Smart Reservoir Management is a result of collaborative and multiple discipline Team Work.

This Green Field was recently commissioned and it was put on production last year. It is a model Digital Oil Field having two artificial islands built to drill all its wells with smart completions like ICVs, ICDs and Permanent Downhole Gauges in all Oil & Gas Producer Wells. This paper will describe the benefits of real-time data utilization for better and most efficient Field/Wells Monitoring along with Better and quick decision-making. Flow tests are performed 2-3 times a week using Multi phase flow meter (MPFM) for each of its wells. Smart and Innovative Dashboard have been created for best screening and grouping of wells as per predefined business rules and alerting Asset Engineers for any wells, which are close to violating any of the Reservoir Management Guidelines, and therefore timely decisions, are made to avoid those violations. Miscible Gas Injection was started from the early days of Field life. Gas Tracers are planned to be injected by the end of this year to achieve the successful and improved surveillance and understandingly Reservoirs and better plan the future wells locations and completion strategy. All Field/well Shut Down duration opportunities are utilized for Pressure Build-up analysis for Oil Producer wells and therefore considerable cost of running Memory gauges and intervention operations is also saved. Successful Digital Oil Field is a result of collaborative and multiple discipline Team Work. Lessons learned and recommendation for any new Digital Oil Field are also presented in the paper. Innovative Dashboards have been created to for best screening of wells and alerting for any wells, which are close to violating any of the Reservoir Management Guidelines, and therefore timely decisions, are made to avoid those violations. The standardized data repository is developed as data integration layer using OSI PI platform products to seamlessly merge real time data with manual data to create a single data reference architecture. This has been a powerful enhancement to ensure a single version of the truth.

Abu Dhabi Marine Operating Company (ADMA-OPCO) has made significant progress in its vision to develop Digital Oilfields in their new fields as part of the company's new field development strategy alongside the implementation of new technologies and upgrades in mature Brownfields, as documented in SPE 171713 (ADIPEC 2014) and SPE 137668 (ADIPEC 2010).The building of a historian system infrastructure foundation was the first step toward the automation of dataflow from various field assets to the company's headquarters. This was essential to ensure verified, clean and accurate real time data are provided to users' desktops.The implementation of fit-for-purpose well-centric production workflows helped to realize the different needs of the production and reservoir teams, solving their day-to-day problems and optimizing field production. The workflows included String Status determination, Rate Estimation, Productivity Index Estimation and Well Model integration and Validation as well as Well Integrity Surveillance.A gap though was recognized in delivering an easy to navigate, graphical, interactive, web based view of the combination of real time data, data from the company's in-house developed production data management and accounting system, the corporate petro technical data archive and contextual data. A new visualization tool and modernised automated workflows were therefore developed and implemented on one of the company's fields to address this challenge, the subject of this paper.Current implementation includes a centralized, web-based integrated surveillance tool which is key to manage production performance and gain comprehensive insight into the operations through overall asset surveillance, quick analysis and reporting of key performance indicators including trends of actual production against plan, downtime analysis and well centric production workflows. A scalable, future proofed Field Surveillance Solution (FSS) was implemented. FSS has been built on top of a Production Operations Platform; which provides a single, integrated platform that connects operations for a broad range of disciplines. With cross-domain workflows and integration with other platforms and products, users can see their asset performance in a single environment, regardless of the asset type, size, or location.FSS provided a state-of-the-art platform to visualize the data in an intuitive way simplifying the navigation from a high level overview of all company production to field level, followed by tower level and 2 SPE-183369-MS well level views in detail based on the historian live data and the company's in-house developed production data management and accounting system. This paper details the implementation of integrated field surveillance workflows to facilitate well and reservoir management for production optimization, reducing downtime, and faster decision making to improve overall operational efficiency.

ADMA-OPCO is currently pursuing the development of several undeveloped structures offshore Abu Dhabi. in addition to the two giant fields that have been on production for many years. At ADIPEC in 2010, ADMA outlined plans for real time well surveillance offshore. This paper describes the implementation of the first phase of these plans for three existing facilities, one of the new fields, and HQ. This paper presents some of the details of that implementation and the opportunities this creates for improved well management.The paper covers:• Hardware architecture and design • Software philosophy and integration with existing capability at ADMA OPCO • Areas of business value incremental to prior practices • Workflows and visualization of key well and facility dataThe challenges ADMA-OPCO faces offshore Abu Dhabi dealing with a high number of complex wells, are to ensure adequate drainage and optimum flux rates, to enhance overall recoveries, from reservoir intervals in both existing, and more complex new fields. Real time well and facility data, transformed with the addition of both modelling capability and workflows, can translate into automation of some key processes and the addition of value by guiding scarce engineer time into the areas requiring the most attention. With ADMA OPCO's activity growth, the well to engineer ratio is increasing. To enhance organizational efficiency, ADMA will be able to automate some previously manual tasks by implementation of automated workflows.A phased approach to the introduction of real time data in an evolutionary, rather than revolutionary approach, preserving and augmenting the functionality of existing tools enables the implementation to follow the pace of introduction of additional control and surveillance capability into the Brownfield environment.
