OMMICA is a low cost alternative to GC for methanol detection on crude oil, condensate, water, and gas

Page last modified
April 11 2024

The OMMICA MeOH analysis consists of a simple, highly accurate, portable colourimetric test to determine methanol in crude oil and water.

Accuracy is gained by addition of accurately measured reagents to a sample. This is then reacted at a specific time and temperature, to control the reaction and the resultant colour gives the level of methanol.

Absorbance of the reacted sample colour is measured using a colourimeter to give an accuracy of +/- 1ppm.

The analysis has been developed to be as accurate as gas chromatography, but allow on-site testing to take place in the field or offshore, through use of portable equipment.

Pros & Limitations
Significant cost savings on traditional analysis methods
Designed to be easy for non-specialist users to use well
As accurate as Gas Chromatography
Designed to be used on- and off-shore
Water extraction of oil not required before analysis of oil samples
OMMICA is not an ASTM method, however it correlates well with the standard ASTM method using GC
The OMMICA method may require a couple of hours training for optimum results (can be provided).
Specification Title Specification Description
Areas of application
FPSO, custody transfer, oil storage tanks, pipeline monitoring, restart after well shut-down
+/- 2 ppm
Range (standard)
1 to 750 ppm (oil), 20 to 1500 ppm (water)
Range (extended)
Up to 10% (oil), up to 80% (water)
Detection threshold
< 1 ppm in oil, < 10 ppm in water, < 10 ppm in gas
Up to 100 samples/day possible
Cost reduction
Low set-up cost compared with GC. Low ongoing OPEX
Can be effectively used by non-specialists
Dedicated YouTube training videos channel, summary videos on website, in-person training can be provided if required
3rd party testing confirms equivalence with ASTM method (GC) (Major analytical contractor)
Operational impact
No need to wait for samples to be helicoptered back onshore to a lab, and for a third party to analyse samples, before decisions can be made
Suitable for use on or offshore. Only requires 1 m2 (or less) of working space. Robust equipment.
