Euler 3D Inversion

Gravity and magnetic interpretation module features among other components Euler 3D inversion. It applies Euler deconvolution to reconstruct the 3D spatial distribution of the source, without needing prior data. This process enables fast determination of both the horizontal position and depth of the source body, allowing for efficient and reliable interpretation of gravity and magnetic data results.

Euler Solution Set – Using the analysis of observation data, the scale of geological structures is determined, followed by the definition of the search window size and the selection of the structural index based on predictions of potential geological formations. This allows for the rapid calculation of the 3D solution of the Euler field source, which is subsequently stored in the Horin database for future reference, including drawing and analysis. The Euler solution set is then displayed on a map. While the initial set of solutions may be extensive, it can be filtered using reliability indicators that are automatically generated, ensuring that only the most reliable 3D solutions are retained for further interpretation and analysis.

3D Gravity and Magnetic Forward and Inversion

Horin® Gravity and Magnetic 3D Forward and Inversion enables both individual and combined 3D forward modeling and inversion of gravity and magnetic data, starting from an initial geological model, for example, an implicit 3D geological model. By applying 3D inversion to gravity and magnetic data with the guidance of initial information, this method can incorporate known prior data or inversion constraints to extrapolate insights into areas lacking exploration data, based on the information available from explored regions. This approach helps minimize uncertainties in gravity and magnetic inversion, leading to more dependable inversion outcomes.

Method 1 for Creating the Initial Constraint Model: 3D Mesh Automatic Partitioning + Human-Comuter Interactive Polygon Interpolation for 3D Model Generation Across Multiple Cross-Sections + 3D Regular Model

Horin Software gravity and magnetic 3D inversion creation module of initial allows for interactive inversion of various theoretical models, such as spheres, ellipsoids, plates, and cylinders. Besides, allows for the manual use of polygon tools to define model boundaries based on existing data, while incorporating 3D interpolation to generate 3D models. Each model can have its own set of average physical properties and distribution ranges, which enhances the accuracy of the inversion results.

Method 2 for Creating the Initial Constraint Model: Converting Complex Implicit 3D Geological Model to Initial Model

Horin Software enables the assignment of varying initial, minimum, and maximum values for density and magnetic susceptibility to the complex implicit 3D geological models created within the platform, based on different geological units. This acts as the initial model for the 3D forward and inversion of gravity and magnetic data. By integrating existing geological information, this initial model enhances the reliability of the gravity and magnetic 3D inversion performed with this initial constraint model.

Gravity and Magnetic 3D Forward and Inversion Calculation

The complete 3D voxel gravity and magnetic forward and inversion offer distinct advantages compared to 2D gravity and magnetic forward and inversion. One key benefit is the notable difference between the 2D constraints of the inversion data and the 3D constraints of the geological model data. This inherent multidimensional constraint helps to substantially minimize uncertainty in gravity and magnetic inversion, significantly improving the reliability of the results.
