Estimation of in-place oil and oil/gas volumes and justification of final oil recovery efficiency
Analysis of field geological structure based on available data in tectonics, stratigraphy, properties of enclosing rocks, saturating fluids, correlation productive stratum production history.
Productive strata correlation, structural imaging of marker surfaces and productive strata, mapping of initial and current oil-filled thicknesses, profiling of lithologic columns and mapping of water-oil and gas-oil contacts.
Estimates of initial oil, dissolved gas, sulfur and associated gas components in place reserves. Analysis of estimated reserves change.
Process and feasibility analyses of final oil recovery efficiency justification (recoverable reserves).
Elaboration of recommendations on field further exploration. oil and oil/gas fields development technology
Creation of reservoir models
Based on integrated interpretation of GIS, seismic survey data, results of 2D/3D core analysis and existing perception about of depositional conditions, building of constant geological hydrocarbon deposit 3D model (Production Association of ROXAR (IRAP RMS) and SCHLUMBERGER (Petrel) companies).
Estimates of reserves based on built geological model. Dimensional re-scaling of models for hydrodynamic calculations.
Adaptation of hydrodynamic model parameters based on development history data. Building of constant hydrodynamic fluid filtration model (Production Association of ROXAR (Tempest MORE) and SCHLUMBERGER (Eclipse) companies).
Calculation of alternative development process parameters for design engineering, production control and optimization.
