To solve the basic problems of geological exploration such as the study of the sedimentation environment and structural features of the productive intervals, prospective traps prediction, preparing fields for production, it is important to plan the upcoming seismic exploration works professionally.
Special attention is paid to the choice of acquisition configuration and sources type.
When planning of geophysical exploration works and seismic survey design, it is important to put additional capability of seismic records for future (in 4-5 years) reprocessing and reinterpretation on the higher technical level.
When creating data processing workflows and seismic data interpretation it’s very important to use the most up-to-date technologies and methods which will be the most appropriate for the seismic and geological conditions of the survey area.
The main object of processing is to get geologically correct, high quality seismic data to create a structural-tectonic framework and productive reservoirs properties prediction in the inter-well space.
Interpretation-driven processing supervising can solve this issue.
Each stage of processing is controlled by well to seismic matching, creation and analysis of sedimentary slices in the prospective interval for a variety of seismic attributes, including coherence.
Software we use: SeisEarthXV, Vanguard, Stratimagic (Paradigm)..
The optimal solution for traps geometrization, reservoir properties prediction of productive formations, paleo-depositional environment reconstruction is achieved through a detailed study and analysis of all geological and geophysical data.
Volume multi-survey, regional-to-prospect interpretation of 2D/3D seismic data allows to create balanced structural-tectonic models.
Such procedures as modern automatic and semi-automatic horizons propagation and faults tracking, different mathematical algorithms, including geostatistics to build the final maps are widely used.
The variety of modern technics are used on stage of dynamical interpretation: volume attributes analysis, seismic facies analysis, amplitude inversion, including acoustic, elastic, simultaneous (stratigraphic) using angle stacks subset and neural network inversion.
Interpretation of well log data is carried out both in blocks and in point-to-point mode and includes reservoir delineation, volume of clay, porosity and saturation calculation, validation of fluid contacts etc.Cluster analysis of well logs and petrophysical substantiation of reservoir properties prediction by seismic data are carried out.
Software we use: SeisEarthXV, Vanguard, Stratimagic 2D/3D, VoxelGeo, Geolog (Paradigm); GeoTeric (ffa); KINGDOM (IHS); TechLog (Schlumberger); GeoOffice Solver (Tvergeofizika LLC).
Different approaches are used when creating geological models including stochastic. The geological 3D base model always incorporates a sedimentation reservoir model, based on the combined facies analysis of regional data, seismic data, well logs and core data. Reserves calculation is carried out using deterministic and probabilistic approaches. Choice of an optimal field development scenario is based on the calculations in the framework of hydrodynamic models.
Software we use: Petrel (Schlumberger); Irap RMS, Tempest More (Roxar); Isoline..
