Title: Leif Abrahamsson: Innovator in Geophysical Modeling
Introduction
Leif Abrahamsson is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of geophysical modeling, holding 2 patents that showcase his innovative approaches to electromagnetic data inversion and modeling techniques.
Latest Patents
Abrahamsson's latest patents include groundbreaking work in electromagnetic data inversion. This patent involves determining an electric field associated with electromagnetic (EM) data within a predetermined sensitivity area around multiple source positions. The process iteratively inverts the electric field for a subsurface resistivity EM model indicative of a subterranean formation. The results of this iterative inversion are stored, and a linear system of equations is generated based on the inversion, which is solved at each iteration until a convergence criterion is met. This method allows for the production of a resistivity map based on the updated subsurface resistivity EM model.
Another significant patent focuses on fast modeling using interpolated starting points. This technique relates to forward and inverse modeling of geophysical formations through interpolation. The method generates a system of equations based on a background model describing a geophysical formation. It also includes generating a first set of solutions for the system of equations using initial base points from geophysical survey data and interpolating to produce solution approximations for a second set of data points.
