It is generally accepted that the streaming potential across the mud-cake is compensated by that across the shale.
2.
The streaming potential appears when mud filtrate is forced into the formation under the differential pressure between mud column and formation.
3.
The dominant application of the electroseismic method is to measure the electrokinetic effect or streaming potential ( item 2, above ).
4.
It is observed that when the pressure-driven solvent flowing through a charged nanochannel, it can generate a streaming current and a streaming potential.
5.
The streaming potential is produced when the flow takes place across mud-cake in front of permeable formations, across permeable formations being invaded, and across shale beds.
6.
"' Streaming potential "'originates from the flow of an electrolyte ( water ) over naturally charged solids ( i . e ., surfaces that acquired electrokinetic or " zeta " potential ).
