Around the New Year LUKOIL Uzbekistan conducted a series of educational courses for employees of Uzbekneftegaz, the state-owned national holding company. The first part of the course was focused on geological modeling, while the second concerned hydrodynamic modelling and development planning at oil and gas fields.
Ignaty Volnov, Head of the Geological and Hydrodynamic Modeling and Monitoring Department at LUKOIL Uzbekistan, delivered the keynote lecture to a large audience at the Institute of Geology and Oil & Gas Exploration in Tashkent. He shared some of LUKOIL’s practical experience using geological and hydrodynamic models in the field, including planning exploratory wells, R&D and optimizing well operating technology. Volnov demonstrated examples of how to build and use models that integrate reservoir simulation, gathering systems, on-site infrastructure and equipment.
Ignaty Volnov: “I’m sure that the knowledge and skills we shared with our partners will be used in the field and will help out Uzbekneftegaz a lot. And we’ll be proud seeing the successes of our colleagues, knowing that we had a little to do with it.”
LUKOIL’s specialists conducted the remaining courses at the Institute’s laboratories, which were equipped with the latest technological tools in geological modeling. Participants were able to experience all the phases of creating a model of an oil well: entering data, generating a map, building a structural and tectonic model of the surrounding area, making a lithological and petro physical model of the relevant underground layers of earth and estimating its hydrocarbon reserves.
They also got to see examples of different types of mathematical algorithms used in modeling, the plusses and minuses of each one and learned about the methodology of estimating reserves and geological risks. The lecturers used real examples of wells operated by LUKOIL Uzbekistan and Uzbekneftegaz to drive home the key points. At the end of the first part, all participants successfully passed a test which required them to build their own geological model.
The second part of the course took place at the Uzbek Oil & Gas National Research Project Institute. LUKOIL Uzbekistan specialists Alexander Zhukov, Ruslan Mambetov and Rafael Minyaev were in charge.
The lectures on modeling theory covered all aspects of the process in detail, including mesh geometry, rescaling the properties of rocks and other geological formations, determining relative permeability ratios, creating fluid models and calculating a deposit’s initial parameters.
Just like in the first part, the lectures were followed up by lab work in which participants had to create filtration models for two oil reservoirs in Uzbekistan using the provided programming tools. They concluded by calculating uncertainty and risk at an oil field.
The best students were scored in a final exam at the end, which consisted of a theoretical part, a practical assignment in adapting a model and an oral interview. Both companies agreed that the event was a great basis for exchanging experience. Uzbekneftegaz benefited from its specialists receiving training in new technologies, while LUKOIL Uzbekistan is always interested in expanding cooperation with its main partner inside the country. In the end – everyone benefits from better efficiency and safety at Uzbekistan’s oil fields.
A geological (static) model presents objects related to oil & gas development and the surrounding geological environment in the form of a 3D set of cells.
A hydrodynamic (filtration) model takes into account, among other things, the characteristics of those cells such as filtration parameters, fluid properties and the industrial and technological indicators of an oil well’s work, which change over time.
