- Measuring Hydraulic Fracture Width Behind
Casing Using a Radioactive Proppant, J.C. Reis, Kevin Fisher, David Holcomb,

ABSTRACT
Measuring Hydraulic Fracture
Width Behind Casing Using a Radioactive Proppant
Knowing the width of a hydraulic fracture
behind casing can be useful in evaluating both reservoir performance and
fracture design methods. This paper presents a method to obtain the widths
of hydraulic fractures behind casing using radioactive, isotope-traced
proppants. A tool-specific relationship between the gamma-ray flux detected
in a wellbore and the fracture width was developed using Monte Carlo
stimulation of gamma ray transport around a wellbore. This method provides
fracture width estimates with a vertical resolution of about one foot. The
method has been successfully used in the field and compares favorably with
other methods for evaluating fracture widths.
