The target injection determination is one of the major issues in waterflooding management. The study resulted in a fully automatic approach to the waterflooding management via the block analysis based on continuously updated hydrodynamic models. The authors propose an automated workflow that provides a closed cycle for waterflooding management: from estimation of target voidage replacement ratio (VRR) per blocks, calculation of recommended well injection rates and monitoring of the plan implementation on optimum VRR per blocks. The paper describes a new approach to key two problems arising from the analysis of waterflooding block performance: the identification of block boundaries with minimum cross-flows between blocks and the correct production / injection allocation (distribution) for wells located on the blocks boundaries. A real-field example, demonstrating the application of the proposed technique, includes the construction of a three-dimensional hydrodynamic model, automatically updated on a monthly basis using actual production / injection data with the streamline map generation. After that, also automatically, the adjustment of waterflooding block boundaries takes place (with the indication of poor drainage areas), with calculation of well allocation factors. The data derived are used in waterflooding performance analysis and block ranking based on a given set of parameters.
We present a novel, data-driven approach to integrated well/reservoir performance analysis and opportunity identification for mid-to late-life pattern waterfloods.The Salym group of oilfields is located onshore in Western Siberia, Russia's prime oil producing province, and is operated by Salym Petroleum Development (SPD), a 50-50 joint venture between Shell and Gazprom Neft. The main productive formation, comprising strongly layered, deltaic/fluviatile sandstones, has been developed as a pattern waterflood, with over 950 deviated wells drilled since 2004. Overall watercut is currently around 82% and with oil production declining at 6-7% year on year, waterflood management is an absolute strategic priority.The operator has responded to this challenge by investing heavily in waterflood management and performance evaluation. Particularly, a dedicated effort was made to develop the company's enterprise information architecture and create a purpose-built online waterflood management tool (WMT). All Salym geological, completion, production and well status data is automatically quality-checked, stored and updated in an integrated waterflood database and made accessible through the WMT. The WMT provides a wide range of functionality for data visualization, performance diagnostics and analysis. Furthermore, it is coupled to a full-field surveillance simulation model, which auto-updates with new oilfield data as it becomes available and outputs streamlines, well allocation factors, maps of remaining oil distribution and pattern-and block-level calculated properties.These technologies have enabled the development and implementation of a structured methodology for waterflood performance evaluation that involves systematic assessment of blocks of 20-50 wells in the form of an Annual Field Review (AFR) followed by a series of deep-dive Integrated Block Reviews (IBRs). During the AFR, each block is assessed against a set of KPIs and scored and prioritised in terms of its health status and projected recovery shortfall. Based on this prioritisation, blocks are scheduled for review in an IBR during the course of the year. The IBRs focus on individual wells, patterns and reservoirs and during the reviews concrete well, reservoir and facilities management (WRFM) opportunities are identified to address performance gaps and sweep or accelerate remaining oil. These opportunities are captured in an online opportunity register coupled to an online database for workover strategy preparation.The framework of technologies and processes presented in this paper was instrumental in planning and executing over 260 WRFM activities (not including simple pump change-outs) across the Salym fields in 2014, delivering in excess of 3.2 Mln bbls of in-year oil production.
Many experts admit a big gap between reservoir simulation and daily management of oil and gas fields. Because only a limited number of specialists can use the results of modeling and models get out of date quickly. The necessity to reduce access and update time has driven to development of a Live Model concept. It will reduce the gap between modeling and practical oil and gas field management.The targets of Live Model concept are:• use models as interactive means of teaching;• make models available to everyone, everywhere, anytime;• build updating and monitoring tools for models. In accordance with Live Model concept we developed web-system which enables to perform model monitoring and analysis of reservoir simulation results. Using this tool any specialist by means of a web-browser can do the following:• make analysis of dynamics well data;• make maps, streamlines visualization;• estimate the quality of the models history matching;• create and calculate a simple model. This web-system can act as an integral part of corporate information-engineering portal. Then we have opportunity to use dynamic production data, which is stored in corporate database, and automatically update Live Models. The interaction of web-system for models monitoring and analysis with the corporate database and models accessibility helps the oil and gas companies to use modeling results in the process of decision-making more efficiently. Another crucial factor is the opportunity to employ Live Models as training aids, which significantly reduces learning curve and increases the quality of training.
