Gazprom Neft has successfully completed testing of its proprietary digital enhanced-oil-recovery (EOR) system. This software helps analyse thousands of field-development scenarios and choose the best options. According to estimates from its developers at the company’s Science and Technology Centre, implementation of this new digital tool could deliver an economic benefit of more than RUB500 million over five years at Gazpromneft-Vostok’s and Slavneft-Megionneftegaz’ pilot fields alone.
The ERA:OptimA artificial intelligence system optimises field development, facilitating the most effective geometric positioning of new wells and the best operational regime for existing wells, based on 3D modelling. Following reengineering on a pilot project at the Gazpromneft-Vostok Krapivinskoye field, the optimum scenario selected for developing this asset is expected to facilitate a RUB300 million increase in profitability in the medium term. This new digital tool has offered an effective solution, expected to increase production by eight percent and profitability by 11, on implementing a project at the Achimovskoye field, operated by Slavneft-Megionnneftegaz.
Until recently a significant proportion of the calculations made in preparing a field for development were undertaken by oil technicians by hand, with evaluation of just one option taking several weeks. Now, the system automatically positions wells, defines the parameters for managing these, initiates production calculations, calculates the economic indicators, and then presents specialists with a selection of the most effective scenarios.
Calculations undertaken indicate that the scenarios identified by the system are
The ERA:OptimA system has been developed as part of the Electronic Asset Development (EAD) element of Gazprom Neft’s Technology Strategy.*
Mars Khasanov, CEO of the Gazprom Neft Science and Technology Centre, stressed: “The Electronic Asset Development initiative is a package of digital products that help us optimise our entire oil-production chain. Every piece of software within that package works in synergy with the others, delivering a multiple benefit in terms of outcomes. Thanks to our extensive experience in field development, and the quality of our expertise, we can successfully select algorithms to address most routine tasks. The less routine engineers have to deal with, the better their work.”Mars Khasanov CEO of the Gazprom Neft Science and Technology Centre
Gazprom Neft’s Electronic Asset Development (EAD)* project is developing digital initiatives in all areas of exploration and production, including geological prospecting, geology, drilling, development, production, and field construction. Under implementation since 2012, the EAD initiative became part of the company’s Technology Strategy in 2014, and is now a key area of focus. The company’s technology strategy was updated in 2018 in response to new production and business objectives of various Gazprom Neft subsidiaries. Approximately 40 projects are currently in hand under the EAD initiative.
