QEMSCAN petrography

QEMSCAN® by FEI is an automated mineralogy system producing rich digital petrography data. These fully digital data sets are valuable inputs for subsurface workflows, including petrophysical modelling, basin modelling, reservoir quality assessment and sediment provenance.

Rocktype works closely with FEI as a technology development partner for the oil and gas industry and is one of a handful of geological consultants providing commercial QEMSCAN services globally.

Our partnership with Rocktype is an important step in further developing use cases and technologies that will ultimately drive economic drilling, completions and recovery decisions.
— Rudy Kellner, VP of FEI’s Industry Group

A traditional petrographic workflow combines optical petrography for modal mineralogy and textural data with X-ray diffraction (XRD) for bulk chemistry and clay typing. QEMSCAN analysis saves time and money by generating all these data in a single process with a resolution and numerical detail not available from other techniques.

Rocktype provides a flexible set of QEMSCAN services tailored to the oil and gas industry. These can be purchased separately or in combination and are available on core, cuttings and sand. The products are defined in terms of the resolution and the total scan area. A coarse resolution scan is a cost effective source of bulk porosity and mineralogy data while finer resolution gives greater insight into morphology and boundary phases.
