Process to improve extraction of crude oil and installation implementing such process

Abstract

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, characterized by the fact that a hot fluid constituted of hydrocarbons is made to circulate so as to bring the 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, the hot fluid being mixed with the hydrocarbons extracted via a liner or drain in the productive zone such mixture thus formed being recovered at the surface by means of an pumping pipe.
