Application of 3D Airborne Electrical Survey Data Processing in a Distributed Computing System when Solving the Problem of Searching for Polymetallic Ores

An example of the use of 3D processing of airborne electrical survey data in solving the problem of searching for polymetallic ores is presented. Data processing is based on solving a 3D inverse problem, in which the field from the geoelectric model and the field of influence of its individual parameters are calculated using finite element 3D modeling. To solve the inverse problem, a heterogeneous distributed computing system is used. It consists of multi-core computers connected by a network. The paper presents the mathematical model used to solve the inverse problem and some features of the implementation of calculations in a distributed system, which are related to taking into account the computational complexity of the subtasks and the load on the computing nodes by other applications. The results of testing the 3D inversion system on airborne electrical survey data obtained at a polymetallic ore deposit are presented. The 3D inversion results show good agreement with the drilling data.
