XRF on site
On-site X-Ray Fluorescence can provide elemental composition analysis of samples on site. Samples can be analyzed rapidly to provide lithological information. This technique provides information that can identify downhole lithology, guide geo-steering operations, and help determine the appropriate drilling equipment to be used. XRF is also useful in determining subtle changes in geochemistry of reservoir rocks. Although XRF analyzers cannot analyze hydrocarbons, they can be used to characterize reservoir properties that influence porosity (cements), permeability (clays, cement type), fracture population (Si content), and productivity (e.g. V, Cr, Mo content).
- XRF testing on drilling samples, including sample preparation.
- Geologists can customize which elements they prefer to view on the mud log or have a separate plot.
- Can infer mineralogy based on the elemental composition.
- Does not interfere with downhole tools.
Our XRF units are the most sensitive and accurate of any on the market. We can detect trace elements down to 3ppm in a sample. Samples are ground up to an average size of 68 micrometers. A sample spinner moves the sample slowly while the analysis is performed, so as to get readings from multiple points in the sample.
