SPECTRACHEM® is a patented chemical tracer technology uniquely
designed to evaluate frac fluid flowback profiles and movement through the reservoir.
The SPECTRACHEM® service involves injecting individual chemical
frac tracers (CFT’s ) at low concentrations into different frac stages or segments
of a single or multi-stage stimulation procedure. Subsequent flowback samples from
treatment and offset wells are analyzed providing precise flowback profiles and
offset well interference recognition.
SPECTRACHEM® tracers are routinely used to quantify and profile
frac fluid clean-up and flowback efficiency over time. SPECTRACHEM®
is also employed to track fluid movement through the reservoir and fracture from
treatment well(s) to nearby offset well(s) for informed well spacing decisions.
SPECTRACHEM® is essential in understanding:
Direct measurement of chemical response in treatment and offset wells provide the
only means to determine many completion factors, and is routinely used for optimizing:
Samples collected according to a pre-determined sample schedule provide a chronological
analysis of flowback. These samples are analyzed at ProTechnics' state of the art
Chemical Tracer Laboratory in Houston, TX using proprietary processes and procedures
in conjunction with analytical analysis capable of tracer detection to the low ppt
range. Stringent quality control measures are in place to ensure the highest level
of accuracy of all sample analyses.
SPECTRACHEM® tracers are compatible with commonly used stimulation
fluids and are:
