A hybrid method for inversion of 3D AC resistivity logging measurements
Hybrid strategy hp-HGS for solving inverse problems. Global step solved by Hierarchical Genetic Search (HGS) coupled with self-adaptive hp-Finite Element Method (hp-FEM). Local search performed with BroydenFletcherGoldfarShanno (BFGS). hp-HGS algorithm adapts the length of the genetic code and the accuracy of the direct solver. Application to 3D AC resistivity logging measurement simulations in deviated wells.
