Patent ID: 7621333

Claim:
A hydrocarbon extraction process enabling an acceleration in the production of the productive zone of the oil deposit of a well and an increase in the cumulated quantity of hydrocarbons, wherein a hot fluid comprising liquid hydrocarbons is made to circulate so as to bring said productive zone locally to a higher temperature by conduction in order to fluidify the hydrocarbons imprisoned in an underground reservoir, by means of a thermally-insulated pipe, said hot fluid being mixed with the hydrocarbons extracted via a liner or drain in said productive zone such mixture thus formed being recovered at the surface by means of a pumping pipe; wherein the production is such that the arrival of frigories via the hydrocarbons extracted from said reservoir is less than the quantity of heat diffused mostly by conduction in the reservoir and whose flow is maintained at less than 3 barrels per day and per linear meter of drain or liner.
