Paper Number: SPE-17317-PA
Published: 01 November 1988
...A.D. Hill; Kathryn E. Boehm; T.J. Akers Summary. The accuracy of a radioactive-tracer log depends on the tracer rapidly mixing with the wellbore fluid and traveling with the same velocity as the wellbore fluid. In addition, log quality depends on the ability to measure the tracer transit time from...

... tracers. We will show how sonic anisotropy and radioactive tracer logging methods can be used to better understand the fracture geometry and aid further design work. The paper will present data from two (2) wells in the Walloon Coal Measures of the Surat Basin where both RA tracers and sonic anisotropy...

... to determine the locations of the individual tracers. These gamma-ray data contain information regarding the radial distributions of the tagged materials as well as the variation of isotope concentrations with depth. The interpretation of radioactive tracer logs can be assisted by prelog job design and postlog...
