Continuous Scanning X-ray Fluorescence

Developing chemostratigraphic relationships during project exploration and operational phases allows operators to correlate complex reservoirs or evaluate lateral landing zones. High-Resolution Continuous Scanning XRF and supplemental isotopic testing provide large elemental datasets that can enhance complex geochemical models.

Core Slab

The latest in non-destructive elemental testing, Core Lab’s CS-XRF can build a detailed elemental profile on slabbed core and plug faces with millimeter precision. The continuous elemental concentrations provide geochemical content and distribution for better evaluation of vertical and horizontal heterogeneity in boreholes. Develop lithofacies clustering, mineralogy models, and chemofacies or identify proxy elements controlling organic content with CS-XRF.

Plugs or Cuttings

Given the nature of high-resolution XRF testing, difficulties arise when comparing complementary testing that requires homogenization, such as X-ray diffraction (XRD). The CS-XRF includes the added capability of testing pulverized and homogenized sample material, thus providing a true one-to-one mineralogical and geochemical correlation. Additional possibilities include building an elemental profile of time-lapsed sampling such as cuttings, elemental make-up of corrosion products, or understanding chemical variations in minerals detected in XRD tests.
