Hydrolysis Mechanisms of Alkynyl Benzonates,  Tosylates, and Phosphates (1988).*  (Continued)  Primary Examiner  - Doug Hutton, Jr.  Assistant Examiner  - Avi Skaist  (74)  Attorney, Agent, or Firm  - Craig W. Roddy; Tumey  L.L.P.  A method of treating a subterranean formation including  providing a treatment fluid comprising a hardenable acid  curable resin and a hydrolysable strong acid ester. The  treatment fluid is combined with a diluent fluid and is  introduced into a subterranean formation. Upon the hydro› lyzing of the ester in the formation and the contacting of  unconsolidated proppants, the treatment method produces  consolidated proppants.
