Application of growing-body potential-field inversion from drillholes

Summary The application of a growing body style of inversion within the program VPmg is presented. The body begins by a seed and grows until there are no eligible neighbours or the data misfit criterion is fit. In this case, the assumptions of source location and physical property are specifically given by drillhole intersects with the body. This style of inversion is useful for reinverting data after drilling in order to produce a more realistic model. The program VPmg allows for density and magnetic susceptibly to be recovered through physical property domains. The algorithm is shown to be promising through two examples: one with density contrast and one with magnetic susceptibility. In summary, the application is another style of inversion that is added to the current hands-on approach to inversion that is performed through VPmg.
