... A PITT tracer must be analyzable in the lowest possible concentration. This will increase the accuracy of its production (recovery) curves reducing the S O measurement's uncertainty. It must also be unequivocally identified in the produced water, as we need to assure that it is only...

... ABSTRACT A new method for interpreting radioactive tracer injection profiles has been developed for use after the tracer has entered the formation. Equations for obtaining fluid injection rates for radial flow and for obtaining in-situ fracture apertures for linear flow are presented. From...

... Abstract This paper presents the results of interwell tracer field work carried out in the McClesky sandstone in conjunction with a surfactant polymer flood pilot, a Dundee limestone pilot designated for an in-depth permeability modification treatment, and a Potter sand steam drive pilot...

... zones in a gravel packed offshore Gulf Coast Louisiana well. Through the use of radioactive tracers and on-line pressure monitoring of the tubing and annulus, onsite adjustment of diverter concentration at various points during the treatment was achieved. The diversion of acid throughout these widely...
