The equations of a continuous medium upon filtration of 
a gassy liquid have been analyzed, and on this basis the equation 
of energy with effective coefficients has been obtained. Analytical 
expressions have been constructed and calculations of the effective 
and apparent Joule-Thomson coefficients and the effective convective 
heat-transfer velocities and heat capacity per unit volume of the 
porous medium in the degassing zones and in the free gas zones have 
been performed. The laws of change in the above quantities depending 
on the pressure and the radial coordinate have been investigated.
