REVIVING OIL WELLS
A new process, patented by a St. Louis (U.S.A.) inventor, is said to make "dried-up" wells produce oil. I Such simple chemicals as hydrochloric acid and sodium fluoride, properly emulsified and injected into the well, are the basis of the invention. It is explained that many oil wells which stop producing are not really dry in the sense that their supply is exhausted. In many cases, the output of oil is stopped only by the building up of solid deposits of salts or wax, which clog the channels or pores of the oil-bearing rock. The chemical J mixture has the property of dissolving such deposits, and, it is claimed, will make the rock more porous than it was originally, by eating out new openings. J
