QEMSCAN 50

QEMSCAN 50 is a fast and affordable alternative to optical point counting and XRD. This high volume scan provides statistically robust bulk mineralogy and porosity data gathered from up to 40 000 data points. 

QEMSCAN 50 Key features
Scan area 10 x 10 mm
Scan resolution 50 μm
Mineralogy data points 40 000
Standard deliverables Modal mineralogy
Porosity (of core)
Mineral map
Minimum project size 20 samples

Applications

The QEMSCAN 50 service is ideal for log calibration, precise stratigraphy mapping or as a screening tool to select samples for higher resolution scans. It is routinely used by development teams to generate precise stratigraphy for a field. Using QEMSCAN 50, geologists can gain a detailed understanding of the mineralogy while petrophysicists can refine the spatial resolution from seismic surveys and help interpret and control log data.

Service Description £/sample
Cuttings lithotyping Determination of up to 5 lithotypes per sample and reporting of agreed rock properties per lithotype. 20
Individual cuttings reporting Quantification of agreed rock properties per individual cutting in a sample. 20

For more add-on options see our higher resolution scan services QEMSCAN 10 and QEMSCAN 4.  QEMSCAN 50 can also be performed over larger areas. Contact us for details.

QEMSCAN Wellsite system by FEI

We created the QEMSCAN 50 service after client demand for a high-volume service with faster turn-around and lower cost. Used by both geologists and petrophysicists, it provides robust mineralogy across the field.

Example project

A reservoir development team needs to understand the stratigraphy more precisely in order to plan a field development. They have 3D seismic data, logs, core from one exploration well and cuttings from a further three. We scan 200 samples at 50 μm.
