Handheld and Benchtop XRF
Chemostrat provide two portable XRF options, Handheld and
Benchtop. Our XRF instruments all have our in-house bespoke
calibration and come with full data correction and QC procedures
to ensure that our services provide the best quality data available
from a portable system in a safe and efficient manner.
Portable Solutions
Chemostrat’s service matrix includes Portable
Solutions that quickly and cost effectively acquire
mineralogical, elemental and magnetic data in
remote locations or at well-site. Due to advances
in technology and our in-house R & D programmes,
we are able to directly analyse core material in
storage facilities and/or cuttings at wellsite.
Depending on clients needs, any combination of
these solutions can be selected to solve your
problems.
Chemostrat are unique in the oil and gas service
sector in providing such a flexible array of portable
solutions. Furthermore, we bring our unequalled
ability to interpret elemental, mineralogical and
magnetic data to our service portfolio.
FTIR
Fourier Transform infrared instruments
provide a means to rapidly acquire
mineralogical data on minimal sample
volumes. Current in-house models for
FTIR provide data for quartz, feldspar,
kaolinite, illite+smectite, chlorite, calcite,
dolomite, siderite, total organic carbon
and total carbonate.
Chemostrat uses the Bruker manufactured
Alpha-P with diamond ATR FTIR system.
It is readily transportable (footprint of 22cm
by 30 cm weight c. 7 kg), allowing use in
core stores, or indeed at well-site. The FTIR is
benchtop and requires a gram of powdered
material. There are no HSE issues with the
use of benchtop FTIR’s and their simplicity
of operation means minimal training is
required to allow data acquisition. The cycle
time on the sample is less than one minute,
meaning that hundreds of samples can be
analysed in a normal working day.

1300 Typical output from HHXRF study on core
The following series of graphs display a direct comparison of XRD and FTIR data.
Benefits Minimal sample destruction (ideally 1g of rock is milled, although in exceptional circumstances we can use less)
Rapid acquisition (analysis time less than a minute) that can be carried out in remote locations
Highly cost effective method of determining mineralogy
Chemostrat recommend that
HHXRF analysis be carried out as
shown above as this is both HSE
compliant and reduces data error.

HHXRF provides non destructive direct measurement of core with no sample preparation
Benchtop XRF provides the data quality of lab-based XRF in a portable system with minimal peripheral equipment
Lithological modelling used to speed up and compliment detailed sedimentary logging of core
Calculation of ChemGR to aid with core – wireline relocation
Indicators of redox facies, provenance, feldspar content, clay mineralogy and coarse chemostratigraphic characterisation/correlation
Benefits
Portable Magnetic Susceptibility
Our Bartington MS2K Magnetic Susceptibility
Sensor is readily transportable and can be used
for the measurement of magnetic susceptibility
in any solid material. It is ideal for direct
measurement of core or for use in the field.
As with the FTIR, there are no HSE issues, the
only caution required is if steel (nails, trestle
tables) is in close proximity, as it can provide
false readings. The rapid analysis means that
typically 500 to 600 readings can be made in a
working day.
If time or geographic constraints are not an
issue, Chemostrat also provides the highest
quality laboratory-based mineralogical,
elemental and magnetic data.
Our ability to integrate laboratory data with
portable data puts us in a unique position to
provide a complete laboratory to site service.
It also means that we can provide calibrations
for our portable instruments that are superior
to suppliers of solely portable-derived data.
