THE METHOD OF INHIBITING CORROSION IN OIL PRODUCTION FROM HYDROCARBON PRODUCING RESERVOIR FORMATIONS PENETRATED BY A WELL, WHICH COMPRISES MIXING A CORROSION INHIBITOR COMPOSITION IN SOLIDIFIED PELLET FORM WITH A PROPPING AGENT IN APPROXIMATELY THE SAME SIZE RANGE, SAID PELLETS BEING SUBSTANTIALLY INSOLUBLE IN A CARRIER FLUID AND AT LEAST SLOWLY SOLUBLE IN FORMATION FLUIDS, SUSPENDING THE MIXTURE OF PELLETS AND PROPPING AGENT IN SAID CARRIER FLUID, DELIVERING SAID MIXTURE THROUGH A WELL BORE TO THE BOTTOM OF SAID WELL, INITIATING A FRACTURING OF SAID FORMATION AT THE BOTTOM OF THE WELL BY INCREASING THE PRESSURE ON SAID CARRIER FLUID TO A DEGREE SUFFICIENT TO LIFT THE OVERBURDEN AND FORCE SAID FLUID MIXTURE INTO THE FORMATION, WHEREBY IT IS DISTRIBUTED THROUGH SAID FORMATION OUTWARDLY FROM SAID WELL, AND WITHDRAWING FORMATION FLUIDS FROM THE FORMATION AND THROUGH THE WELL TO INDUCE A SLOW DISSOLUTION OF THE PELLETS BY CONTACT WITH THE FORMATION FLUIDS UNTIL THE INHIBITOR IS COMPLETELY DISSOLVED THEREIN.
