Abstract
The invention has application only to a first oil well producing oil having a high water cut, said oil well being completed in a reservoir having an increased gas saturation, in the vicinity of the first oil well, arising from injection of gas through an adjacent injection well. The first oil well is treated by injecting through it into the reservoir a slug of non-condensible gas in an amount between about 40,000 m.sup.3 and 200,000 m.sup.3. The first well is then placed back on production and its water cut is significantly reduced.
