The OMMICA™ method
OMMICA™ employs robust equipment which is easy to use, and suitable for offshore applications; the simplicity of the method means users require limited technical experience. Detection reagents are added directly to samples, so no manual water separation step is required when oil or condensate is being analysed.
OMMICA™ uses reagents that react only with the chemical its designed to assess. This means other chemicals don't interfere with results (and why OMMICA™ is prepared specifically for each inhibitor). Unlike other assessment technologies, OMMICA™ can be used on site, on or offshore.
Correlation of methanol results using OMMICA™ methanol in water kits vs GC
The OMMICA™ method for measuring methanol in oil was compared to gas chromatography (GC) by a third party laboratory. The results demonstrate the accuracy of OMMICA™, providing clients with confidence to adopt the method for their operations.
Samples of oil containing concentrations of between 0 and 160 ppm methanol were prepared. These
samples were then split into two aliquots and analysed using OMMICA™ and GC, in parallel, in the same lab, thereby minimising any potential differences. Each sample was tested in duplicate to reduce the
likelihood of anomalous results.
The graph shows that results obtained using OMMICA™ correlate very closely with the results obtained using GC. Both methods give results very close to the prepared spiked concentrations of methanol in oil.
