acidize

v. acidify, make or become acid; (British usage) turn sour; (Petroleum) treat oil-bearing limestone with acid for the purpose of increasing production (also acidise)

To treat oil-bearing Limestone or other Formations with acid for the purpose of increasing production. Hydrochloric or other acid is injected into the formation under pressure. The acid etches the rock, enlarging the pore spaces and passages through which the reservoir fluids flow. The acid is held under pressure for a period of time and then pumped out, after which the well is swabbed and put back into production. Chemical inhibitors combined with the acid prevent corrosion of the pipe
