OJSC Gazprom is the largest gas company in the world, with the richest natural gas reserves. Gazprom dobycha Nadym LLC (GDN), a subsidiary of Gazprom, is the oldest production and transportation enterprise of natural gas in Western Siberia, recovering over 60 bcm of natural gas per year.
The company’s main objective is to ensure efficient gas production at its existing fields and prepare for its new Bovanenkovskoye, Kharasaveyskoye, and Novoportovskoye fields by obtaining appropriate development licenses.
GDN selected Schlumberger as a key solution provider to expand asset operational capabilities, optimize production, and improve economic performance.
GDN and SIS identified Avocet IAM software as a key tool to improve field management. This provided a platform for the integration of reservoirs, wells, and surface infrastructure models in a single cycle for accurate decision making to control field production, optimization, and planning. Understanding field problems as a whole, rather than individual parts, would lead to efficient production, both now and in the future.
Together, GDN and SIS specialists conducted a pilot project on the Yamsoveyskoye gas field, during which they thoroughly tested the effectiveness of Avocet IAM technology before applying it to other new fields.
The pilot project team consisted of participants from Schlumberger and Gazprom dobycha Nadym. This joint, multidisciplinary team (including reservoir, production, and process facilities engineers, as well as economists) was challenged to work together for the first time and with an 11-hour time difference between their locations (Moscow, Tyumen, Calgary, and Nadym).
Schlumberger provided software and consulting services for delivery of a fully integrated asset model. The integrated model included models of the reservoir, wells, gathering system, surface equipment, and economics. Project deliverables were both short- and long-term production optimizations, which could be used for strategic and tactical purposes, supporting daily operations management and production planning.
Successful pilot results were achieved via the advanced infrastructure and integrated reservoir modeling technologies. Optimization capabilities of Avocet IAM allowed the team to perform on-the-fly calculations of operating schedules for the individual wells and the entire field.
Implementation of Avocet IAM and associated software/hardware technology for the Yamsoveyskoye field allowed GDN to integrate all components of its production system into a single, holistic model. The project proved the effectiveness of this technology for solving problems of gas field optimization and forecasting.
The main benefits of the project included the following:
GDN will consider the positive results of the project when developing other new assets. Lessons learned will be applied next to the preparation of technical documentation and selection of software for building Bovanenkovskoye field’s integrated model.
