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™ proppant 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.
- US Nuclear Regulatory Commission (NRC) approved
- 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 of 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.
Proppant Tracing and HSE Best Practices
Our clients appreciate the valuable insights provided by proppant tracing but we recognize that disposal can be a challenge. In response to client feedback, we’ve developed solutions to simplify the disposal process and support this effort with a dedicated team that specializes in HSE and radiation safety.
