Mathematical Principles of Data Inversion
Inverse elastic-wave scattering problems are shown to be ill-posed in general. Standard simplifying assumptions--the first Born approximation, the physical optics approximation, and the stopping power approximation of tomography--are shown to reduce to the same ill-posed mathematical problem, that of inverting a Fourier transform. Practical implications of this fact are illustrated with examples.
متن کاملInversion of gravity data using a binary formulation
S U M M A R Y We present a binary inversion algorithm for inverting gravity data in salt imaging. The density contrast is restricted to being one of two possibilities: either zero or one, where one represents the value expected at a given depth. The algorithm is designed to easily incorporate known density contrast information, and to overcome difficulties in salt imaging associated with nil zo...
متن کاملClues from joint inversion of tsunami and geodetic data of the 2011 Tohoku-oki earthquake
The 2011 Tohoku-oki (Mw 9.1) earthquake is so far the best-observed megathrust rupture, which allowed the collection of unprecedented offshore data. The joint inversion of tsunami waveforms (DART buoys, bottom pressure sensors, coastal wave gauges, and GPS-buoys) and static geodetic data (onshore GPS, seafloor displacements obtained by a GPS/acoustic combination technique), allows us to retriev...
متن کاملReservoir characterization in an underground gas storage field using joint inversion of flow and geodetic data
Characterization of reservoir properties like porosity and permeability in reservoir models typically relies on history matching of production data, well pressure data, and possibly other fluid-dynamical data. Calibrated (history-matched) reservoir models are then used for forecasting production and designing effective strategies for improved oil and gas recovery. Here, we perform assimilation ...
متن کاملMathematical formulation
When trying to model molecular processes, one often comes against the problem of how to compensate between scales. On one hand, there is the fact that observable phenomena occur at the macroscopic scale, and so often times we average out the interactions to get a general equation for our appropriate scale. On the other hand, the microscopic interactions can and do perform interactions with each...
