ABSTRACT:
A method of logging and treating a well to stimulate production from and to efficiently increase acceptance of fluids in the well strata by controlled and selected treatment of formations in the well. The logging method utilizes radioactive materials which are mixed with a macroreticular ion exchange resin having an effective size of between 0.10 and 1.00 millimeters which is pumped into the pressure side of the frac line of the well to mix with pressurized fluid being pumped into the well. The radioactive material preferably has a half-life of less than 150 days and may be introduced in staged stimulation of the well or in an after treatment logging process.
