Elastic Properties
The analysis of petrophysical data can be achieved by the computation of the rock elastic properties, elastic impedance and extended elastic impedance. The resulting outputs are valuable for fluid and lithology prediction.
Gassmann Fluid Substitution
The fluid substitution process is a fundamental part of any rock physics workflow. In this process, users can target the correction of the formation invasion, and calculate the replacement of the reservoir fluids by a combination of brine, oil or gas. Density and acoustic logs are re-created in the fluid saturated rocks.
Shear velocity modeling and prediction
The empirical Greenberg-Castagna approach, with some improvements, is used to model and predict shear velocities. When shear velocity is available for one or several depth sections, it will be used to automatically calibrate on the empirical Greenberg-Castagna model using non-linear optimization.
Backus Averaging
One of the objectives of the Backus averaging is to upscale borehole data in order to get a resolution similar to the surface seismic one.
Reflection coefficient
Reflection coefficients are computed for both P and S-waves for a range of incidence angles. A suite of technique is available for users. Reflection coefficients are commonly used for the AVA analysis.
Time/depth conversion
Depth to time conversion can be achieved by the use of sonic logs, checkshot seismic data or a combination of both. In this process, if needed, a seismic reference datum correction can be applied to the data.
Synthetics/filter
A suite of filters and synthetic waveforms are available to convolve with for two main applications: Generate synthetic seismograms; and to filter the input data.
Quality Control
A suite of interactive bound model chars is available to quality control the input and the processed data.
