- Geological exploration and creation of reservoir models including laboratory analyses of geological, petrophysical, and reservoir properties
- Field development
- Site supervision
- Support with procurement procedures
- Monitoring and operation optimization
Underground gas storage
We provide engineering services for the construction, simulation and optimization of cavern and pore storage facilities.
- Determination of effective storage pressure ranges
- Assessment of storage capacities for various media, including natural gas, hydrogen, and carbon dioxide
- Cap rock integrity assessment, including laboratory testing
- Analysis and reservoir modelling of flow processes in the reservoir
- Application of reservoir simulation models for the design and operation of natural gas storage systems
- Forecasting of pressure evolution, gas deliverability, and cushion gas requirements during cyclic injection–withdrawal operation
- Optimization of storage operations, including injection–withdrawal strategies and water production control
- Assessment of operational risks and support for long-term performance evaluation
- Design and monitoring of brine injection and initial gas filling
- Design, supervision, and evaluation of leak tests
- Storage decommissioning, including maximized withdrawal of working gas volume (WGV) and cushion gas volume (CGV), and planning for subsequent use of the storage site
Gas and oil deposits
We provide services ranging from exploring new deposits to enhancing efficiency in mature fields:
- Evaluation of geological and geophysical exploration data
- Evaluation of well tests
- Laboratory investigations on petrophysics and fluid properties
- Complex 3D geo-modeling and reservoir simulation

Reservoir Simulation
We provide reservoir simulation services to support the analysis and optimization of subsurface systems across UGS, CCS, geothermal, and depleted oil and gas fields. Our work focuses on understanding reservoir behavior under different operating conditions and identifying effective development and operational strategies. The results support high-level decision-making and contribute to safe, efficient, and reliable project performance.
