A new method for 3-D magnetic data inversion with physical bound

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...

3-D Inversion of gravity gradiometer data

We present the development of an algorithm for inverting multi-component gravity gradiometer data to recover three-dimensional (3-D) distributions of density contrast for salt imaging. The algorithm is a direct adaptation of the author’s earlier work on 3-D inversion of magnetic data. The underlying method is based upon a regularized inversion that constructs a density contrast distribution hav...

3-d Focusing Inversion of Csamt Data

We present a method for the solution of 3-D controlled source magnetotelluric (CSAMT) inverse problems. The inverse problem is formulated as the minimization of a Tikhonov parametric functional with a focusing stabilizer. Observed CSAMT apparent resis­ tivities are converted to log-anomalous apparent resistivities, which are linearly connected to anomalous currents via the integral equation. We...

3-D inversion of gravity data

We present two methods for inverting surface gravity data to recover a 3-D distribution of density contrast. In the first method, we transform the gravity data into pseudomagnetic data via Poisson’s relation and carry out the inversion using a 3-D magnetic inversion algorithm. In the second, we invert the gravity data directly to recover a minimum structure model. In both approaches, the earth ...

Fast multiple inversion for stress analysis from fault-slip data

The multiple inverse method is widely used to invert multiple stress tensors from fault-slip data caused by polyphase tectonics. A practical problem of the method is the time-consuming computation related to its iterative procedure. This paper describes a way of accelerating the computation by replacing an exhaustive grid search for the optimal stress tensor by direct calculation using an analy...
