Claim 1
Independent Claim

Claim 3
Independent Claim
86 words
A METHOD FOR EFFECTING SECONDARY RECOVERY FROM A PRODUCING FORMATION COMPRISING THE STEPS OF: PROVIDING A SOURCE OF WATER UNDER PRESSURE; INJECTING SAID WATER INTO A CONDUIT; DIRECTING A PORTION OF SAID WATER THROUGH SAID CONDUIT AND INTO AN INJECTION WELL AND, BY PRESSURE, CAUSE SAID PORTION TO ENTER SAID FORMATION; AND CAUSING, BY PRESSURE, ANOTHER PORTION OF SAID WATER TO PASS THROUGH A PORTION OF SAID CONDUIT, HE DIVERTED THEREFROM AND BE INJECTED INTO THE PUMPING MECHANISM OF A PRODUCTION WELL THEREBY ACTIVATING SAID MECHANISM.
