SPECTRAFLOOD™ is an interwell tracer diagnostic service that
comprises a versatile array of unique chemical tracers designed to track the movement
of injected fluids within the reservoir.
Commonly referred to as a tracer survey, chemical tracers are deployed into target
injection wells and sampled at pattern and off-pattern producers, yielding specific
qualitative information about the reservoir such as:
SPECTRAFLOOD™ tracer surveys are used to optimize flood performance
during any stage of the IOR/EOR process to improve hydrocarbon recovery and decrease
operating costs by reducing water cut and ineffective cycling of injection fluid.
SPECTRAFLOOD™ interwell tracers can be used to identify matrix
bypass events (MBE), such as thief zones, natural fractures, and high permeability
conduits within the reservoir. These ‘short-circuits’ cause the flooding process
to become virtually ineffective and limit the recovery of hydrocarbons within the
To reduce uncertainty, SPECTRAFLOOD™ interwell tracers can
also be used to evaluate reservoir heterogeneity during an IOR/EOR pilot study.
An understanding of reservoir heterogeneity is crucial to the success of any IOR/EOR
process. Interwell tracers provide the only means of directly tracking the movement
of injected water through the reservoir.
Samples collected according to a precise sample schedule provide a chronological
analysis over time. 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 the lab is capable of detection in the low
parts per trillion (ppt) for SPECTRAFLOOD™.
Stringent quality control measures are in place to ensure the highest level of accuracy
of all sample analysis.
SPECTRAFLOOD™ tracers are:
