Optimal exploitation of underground oil and gas reserves requires maintaining high rates
of oil production.The aim of this work is to study the importance of using the conventional fluid adding
Methanol.This is why reservoir stimulation is
necessary, particularly by hydraulic fracturing, with the aim of improving productivity or
restoring the initial state of the rocks reservoirs, by creating a permeable drain extending as
far as possible into the formation so as to facilitate the flow of fluid towards the bottom of the
well.Methanol have relatively low viscosities, which make them similar to linear gels.?
