Tesseral Engineering 1.0.0f

Tesseral Engineering implements accurate and fast calculations of 2D synthetics using a variety of methods (more than 10), ranging from ray tracing to viscoelastic modelling, taking into account 3D TTI anisotropy and several 3D fracture systems, which enables performing modelling of arbitrarily complex geological media in the shortest possible time, including a combination of solids and liquids, with any number of boundaries of any geometry. Flexible toolkit for building a studied medium allows one to use drilling data or well logs, create continuous layers and closed-loop configurations with a fixed or complex distribution of physical properties, such as P- and S-wave velocities, density, damping parameters, porosity with fluid properties, fractures, and Thomsen anisotropic parameters. The software supports importing a model from txt or SEG-Y files and using raster images as a background for drawing model polygons. The modelling method is selected automatically based on the properties of the model, the problem and the expected results.

The user has access to various options for acquisition systems – sources and receivers can be located on the surface of a model, in a water column, at the bottom of water area or in boreholes of any geometry. Each receiver can be defined as a 1/2/3C geophone or hydrophone. Users can set the frequency and signature of the source, assign it as omnidirectional, directional dipole / monopole, or in the form of symmetric oscillations of lateral stresses of a small volume. It is also possible to simulate a solid extended source to imitate the propagation of plane waves or exploding horizons, resulting in a time section t0.

When using Tesseral Engineering at the interpretation stage, the user can upload the section obtained as a result of processing real data, add physical properties and targets (karsts, faults, fracture zones, taliks, etc.) into it, perform modelling and compare the calculated seismic gathers with real ones. Subsequent processing of synthetic gathers allows determining the reliability of interpretation and the limits of capabilities of the given acquisition system on a specific section when solving the geological or geotechnical problem.
