Presentation Overview • Introduction • Cooperative inversion of seismic reflection and gravity data • Methodology • Results • Conclusion Maiara Gonçalves & Emilson Leite EGU2020 2 Introduction • Seismic reflection • Gravity Maiara Gonçalves & Emilson Leite EGU2020 3 Introduction • Solution jointly invert seismic with gravity 1) De Stefano et al., (2011): joint inversion with structural and empirical links 2) Haber and Oldenburg (1997) – structural operator 3) Gallardo and Meju (2004) – the cross product of model gradients 4) Gonçalves and Leite (2019) – cooperative inversion of seismic reflection and gravity data, by optimizing the gravity inverse problem. Maiara Gonçalves & Emilson Leite EGU2020 5 Cooperative inversion of seismic reflection and gravity data Objective function to be optimized Gonçalves and Leite (2019) Maiara Gonçalves & Emilson Leite EGU2020 6 Methodology Parameters to analyze: Reflection Expansion • Sensibility analysis Contraction 1) Simplex Method Shrinkage Adapted from Lagarias et al. (1998). The simplex algorithm is a local search method. Maiara Gonçalves & Emilson Leite EGU2020 7
