In practice,especially when calculated and displayed as a curve,the following values can be used for simplicity:a=1.0,m=2.0.The Deep Induction or Deep Laterolog is used as Rt,usually without any environmental corrections.Porosity is usually derived from the sonic or density,with the proper matrix and fluid parameters for the formations to be encountered.If available in real time during logging,the neutron-density crossplot porosity should be used for the best estimate of porosity.
