Identify and Precisely Determine Near-Wellbore Proppant Placement

SPECTRASTIM™ proppant tracing with SPECTRASCAN® post-stimulation spectral gamma ray logging provides the only means to accurately pinpoint proppant placement and refine completion procedures.

Direct Measurements to Evaluate

Uniform Proppant Placement

Natural Fracture Identification

Proppant Communication

Plug Integrity/Sleeve effectiveness

Gravel and Frac Pack Treatments

Perforation Efficiency

Treatment Uniformity Evaluation: proppant tracers provide the unique ability to directly measure the distribution of proppant near-wellbore.

SPECTRASTIM™ tracing technology involves the injection of uniquely identifiable proppant tracers, designed to target specific stages or segments and different proppant types in hydraulic fracturing operations. SPECTRASTIM™ proppant tracers are manufactured using Core Lab’s patented ZeroWash® process, fixing non-water-soluble tracer into the matrix of a high strength ceramic particle with no potential for wash-off.

  • Safe to transport, handle, store, and dispose

Isotope (half life): Iridium 192 (74 days) | Scandium 192 (83.8 days) | Antimony 124 (60.2 days)

SPECTRASCAN® is a memory spectral gamma ray logging service uniquely able to analyze the effectiveness oof completions operations. Recording a high resolution energy spectrum combined with proprietary spectral deconvolution software analysis, SPECTRASCAN® delivers the industry’s most accurate identification and quantification of the injected proppant tracers. Data downloaded from the tool is merged and correlated with other depth data to provide a realistic understanding of the completion effectiveness. Versatile deployment options provide operational flexibility.

The rugged SPECTRASCAN® design ensures sound operation even in temperatures that exceed 400º F (200º C) and pressures up to 30,000 psi.
