ERT.petro_Archie.Archie_rho_DA(rFluid_Archie=[], sat=[], porosity=[], a_Archie=[1.0], m_Archie=[2.0], n_Archie=[2.0], pert_sigma_Archie=[0])[source]#

Compute ER values at each mesh nodes. If pert_sigma, add a nornal noise of sigma standart deviation and 0 mean (# See eq. 4.4 thesis Isabelle p.95)

Parameters:

  • rFluid (list) – Conductivity of the pore fluid for each soil zone

  • sat (list) – Water saturation for each soil zone

  • porosity (list) – Porosity for each soil zone

  • a (list, optional) – Tortuosity factor. The default is 1.0.

  • m (list, optional) – Cementation exponent. The default is 2.0.(usually in the range 1.3 – 2.5 for sandstones)

  • n (list, optional) – Saturation exponent. The default is 2.0.

  • pert_sigma_Archie (list, optional) – Normal noise to add to the data

Returns:

rho (Converted Apparent Electrical Resistivity (Ohm.m).)
