LTrace Bayesian Linear Inversion provides a deterministic seismic inversion based on the linearized Bayesian methodology for estimating elastic properties from seismic data. This plugin provides both acoustic and elastic inversion. The input data are seismic data, wavelet and low-frequency model of the properties. The results are comparable to a constrained sparse spike inversion but are obtained 6x to 10x faster, since no optimization is required and the solution is analytically computed. The software also implements an approximation on the horizontal continuity model along an input horizon, allowing the user to impose lateral correlation on the results with a low overhead.
Absolute Acoustic Impedance remains a cornerstone of modern seismic interpretation projects. It enables interpreting layer properties without distortions caused by tuning effects. LTrace Acoustic Bayesian Linear Inversion provides a deterministic acoustic seismic inversion using the linearized Bayesian methodology for estimating acoustic impedance from seismic data. The input data are the full stack seismic data, the wavelet and the low frequency model of acoustic inversion.
LTrace Bayesian Linear Inversion provides a deterministic elastic seismic inversion using the linearized Bayesian methodology for estimating velocities or impedances and density. We use angle stacked seismic data – such as near, mid and far – along with low frequency models to quickly perform the inversion.
For the elastic inversion, the software uses the latest Graphics Processing Unit (GPU) technologies to accelerate the inversion processing. If the user has an NVIDIA® GPU, the inversion will be automatically processed using it. Using GPUs provides a performance gain over CPUs of 4 to 7 times in our benchmarks, depending on the model of the GPU and the vertical gate selected at the inversion.
