OASIS MONTAJ: LATERAL AND VERTICAL INVERSION GEOPHYSICAL DATA(GRAVITY AND MAGNETIC)

Описание: OASIS Montaj is a popular software suite used in geophysics for data processing, interpretation, and visualization. It includes a range of tools for the processing of gravity and magnetic data, including the ability to perform lateral and vertical inversions.

Lateral inversion is a technique used to estimate the spatial distribution of subsurface density or magnetic susceptibility variations. This is done by inverting the measured data to create a model that matches the observed data. In OASIS Montaj, this is achieved using the Lateral Inversion tool. This tool allows the user to define a 2D or 3D model grid, choose an appropriate inversion algorithm, and set inversion parameters. The resulting model can be visualized and analyzed to gain insight into the subsurface geology.

Vertical inversion is a similar technique that estimates the depth distribution of subsurface density or magnetic susceptibility variations. In OASIS Montaj, this is achieved using the Vertical Inversion tool. This tool uses a 1D model to estimate the depth distribution of subsurface properties. The user can choose an appropriate inversion algorithm, set inversion parameters, and visualize the resulting model.

To perform lateral or vertical inversion using OASIS Montaj, the following steps can be taken:

1. Import the gravity or magnetic data into OASIS Montaj.
2. Create a model grid using the GridMaker tool.
3. Choose the appropriate inversion algorithm and set the inversion parameters using the Inversion tool.
4. Run the inversion and visualize the resulting model using the 3D Viewer or other visualization tools in OASIS Montaj.

It is important to note that the accuracy of the inversion results depends on several factors, including the quality and quantity of the input data, the choice of inversion algorithm, and the setting of inversion parameters. Therefore, it is recommended to carefully evaluate the inversion results and compare them with independent geological or geophysical information to validate the model.
