Abstract

1486536 Treating wells PERMEATOR CORP 15 Dec 1975 [20 Jan 1975] 51336/75 Heading E1F A method of maintaining and stabilizing the permeability of subsurface hydrocarbon reservoir rock containing clay particles and, where clay damage has occurred, of improving the permeability of the rock, comprises injecting into the reservoir rock an aqueous solution of an alkaline earth metal hydroxide and a salt of an alkaline earth metal, the concentration of alkaline earth metal cation in the solution being greater than 10,000 ppm and the pH value of the solution being greater than 10. The injection is continued for a time period and with a volume which is insufficient to consolidate sand, but sufficient in respect of (a) expansible clay particles to alter their electrical behaviour to cause them, in hydrated form, to occupy a smaller effective volume, and (b) non-expansible clay particles and originally expansible whose electrical behaviour has been altered as in (a), chemically to transform them into clay particles which are capable of permanently adhering to rock substrates. The alkaline earth metal cation may be calcium, magnesium, strontium or barium. Preferable the hydroxide is calcium hydroxide and the salt is calcium chloride.
