Unlocking Reservoir Insights with Quantitative X-Ray Diffraction (QXRD)

In today’s energy industry, having a precise understanding of rock composition is critical for petrophysical calibration, reservoir evaluation, and maximizing recovery. One of the most effective tools for achieving this clarity is Quantitative X-Ray Diffraction (QXRD).
At CoreSpec, our advanced QXRD solutions go beyond basic mineral identification—delivering accurate quantitative mineral analysis (QMA) that directly impacts completion and production strategies.

Why QXRD Matters
Quantitative phase and mineral analysis (QPA) of core and cuttings samples provides the foundation for understanding sub-surface formations. When performed correctly, QXRD helps guide decisions that can significantly boost estimated oil recovery (EOR).
Key benefits of QXRD include:
  • Precise mineral quantification for petrophysical calibration
  • Improved reservoir quality assessments through bulk mineralogy data
  • Enhanced completion strategies that minimize risk and uncertainty

The CoreSpec Advantage – Qmin Full Pattern Fitting
A major challenge in mineral quantification is analyzing disordered structures like fine-grained clay minerals, amorphous compounds (opal A, opal CT, glasses), and organic matter such as kerogen. Traditional model-based approaches (e.g., Rietveld refinement) struggle with these materials because structural parameters are difficult—or impossible—to obtain.
That’s where CoreSpec’s Qmin full pattern fitting strategy stands apart. Unlike model calculation methods, Qmin does not rely on rigid structural parameters. Instead, it uses an extensive library of reference mineral diffraction patterns to calculate accurate mineral content, even in complex or disordered samples
This means CoreSpec can deliver clarity where other methods fall short—ensuring a more complete and reliable mineralogical profile.

Integrating QXRD with Clay Analysis and CEC
QXRD is often paired with additional analyses for a deeper understanding of reservoir rocks:
  • Cation Exchange Capacity (CEC): An objective measure of the smectitic nature of formations, providing valuable input for clay-bound water evaluation and reservoir modeling.
  • Clay Fraction Analysis with Sybilla: For cases requiring detailed clay structure insights, CoreSpec applies advanced modeling to supplement whole-rock QXRD results. This is particularly useful when illite-smectite ratios and smectite abundances must be quantified with precision
By combining QXRD with these advanced analyses, CoreSpec provides operators with an integrated toolkit to answer critical formation questions.

Driving Better Decisions in Exploration and Production
From exploration to production, CoreSpec’s QXRD services help operators:
  • Calibrate petrophysical models with confidence
  • Evaluate reservoir quality and fluid interactions
  • Design smarter completion strategies that maximize recovery potential

At CoreSpec, our mission is simple: deliver the most accurate, actionable data possible to support better decision-making across the energy industry.
