簡介：Earthworks Environment Resources公司最近推出了最新版本的地震反演軟件MPSI v1.2，它是一種隨機反演軟件，增加了已經擁有確定性反演包的用戶的隨機反演技術能力。
Earthworks Environment Resources has launched the latest version of its seismic inversion software, MPSI v1.2. 

MPSI is a stochastic inversion software solution that allows users of existing deterministic inversion packages to extend their stochastic inversion technology capabilities. 

The software allows users to routinely generate the 100+ realizations necessary to compute reliable uncertainty statistics for the Inversion. 

Using spatially varying convergence criterion users can control the relative importance of the seismic and well data in the final inversion and ensure the resulting deterministic or stochastic inversion will tie the well data. During the inversion the user can correct the impedance values for the asymmetric error term which arises due to inversion solving for reflectivity (seismic amplitudes).
