Dictionary:Pseudogeometric factor

{{#category_index:P|pseudogeometric factor}} A coefficient used for estimating the response of a resistivity measurement R_a at different invasion depths:

$R_{a}=R_{xo}J+R_{t}(1-J)$ ,

where R_xo=flushed-zone resistivity, R_t=uncontaminated-zone resistivity, and J=pseudogeometric factor, a function of invasion depth.
