Abstract (en)
[origin: EP1184537A2] The invention relates to a method of stimulating a drilled well for use in the production of oil or gas from a formation, wherein acid or the like aggressive liquid is supplied for decomposing material (51) on the surface of a well bore by use of a tubing (70) arranged within the well bore while forming a space (57) between the tubing (70) and the surface of the well bore, wherein said supplied liquid is discharged to said space (57) through openings (72) formed in the wall of the tubing (70) in the longitudinal expanse of the tubing (70) for influencing the material (51) on the surface of the well bore. The invention is characterised in that the that the well bore (50) is established; that a first portion of the well bore (50) thus formed is provided with a reservoir liner (40) for the production of oil or gas; that the tubing (70) is introduced into the well bore (50) for extending at least into a second portion (S) of the well bore (50) to the profoundly situated end (55) of the well bore. <IMAGE>
