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.

A method of recording the effect of stimulating a well drilled into the earth\s strata, comprising the steps of: recording the existing radiation within the well to form a base gamma-ray log; pumping fracturing liquids through a line leading into the well to fracture the strata and stimulate the flow of fluids trapped in the earth\s strata; injecting a tagging agent of a radioactive material and an ion exchange resin into the fracturing fluids; the tagging agent being injected into the line downstream of where the fracturing fluids are being pumped to prevent contamination of the pumping apparatus; and recording a gamma-ray reading of the well after fracture of the strata to locate the position where the tagging agent has been deposited within the well which indicates the entry of the fracturing fluids through the well bore into the strata.
