The inverse thermal effect of the liquid displaced in 
a porous medium is investigated, with the effect occurring because 
of the fact that, with the thermal conductivity being neglected, temperature 
jumps move with the speed of convective heat transfer. In piston displacement, 
the front moves with a true velocity which several times exceeds those 
of filtration and of convective heat transfer. Due to the faster advance 
of the displacement front, a special zone is formed, in which the 
process of inverse thermal effect of the displaced liquid on the displacing 
one is observed.
