Petroleum engineering

Study of Reservoir fluid properties

• Establishing initial reservoir conditions – definition of pressure and temperature gradients
• Quality check of fluid sampling conditions and laboratory PVT test results
• Modelling of Fluid properties, “black-oil” or compositional.

Well test data analysis

• Using analytical and numerical methods of interpretation
• Evaluation of reservoir properties and connectivity

Saturation modeling

• Based on core studies, well logs interpretation and production test results
• Methods: Groups of capillary pressure curves for different rock types; Leverett J-function, FZI-Index

Simulation modelling

• Black-oil and compositional models
• Production history matching and prediction.
• Tracer injection studies
• Complex reservoirs modeling (fractured, fracked reservoirs, heavy oil)
• Enhanced oil recovery modeling (polymer flooding, surfactant injection, thermal methods, water-alternated-gas injection (WAG))

Production design

• Production profiles
• Reserves evaluation – recovery factor technical and economic evaluation, development plans, trial production project design and technical scheme with integrated field infrastructure facilities (with partners).

Production optimization

• Well performance monitoring and optimization
• Full field production and pressure maintenance program optimization
• Well workover planning and programs for production maintenance
• Uncertainty analysis, identifying risks and opportunities
• Well completions design and optimization
• Nodal analysis for multilateral and horizontal wells
