Proper fluid and proppant placement are critical to a successful propped fracture
stimulation treatment. Despite effective placement of the treatment, well performance
is often detrimentally affected by incomplete gel breaking and fluid recovery. A
technique employing a family of environmentally friendly, fracturing fluid compatible
chemical tracers has been employed for quantifying segment-by-segment fracturing
fluid recovery. Utilizing this technology, it is demonstrated that individual fluid
segment cleanup and recovery can be enhanced by optimizing fracturing fluid selection
and by using aggressive gel breaker deployment schemes. The validation of improvements
in fracturing fluid cleanup and the resultant effects on well performance are presented
using Bossier Sand case histories. Comparisons between crosslinked gel systems and
between conventional and aggressive gel breaker deployment schemes are highlighted.
