Methanol Testing: Will OMMICATM work for me?

We need to measure high concentrations of Methanol, can OMMICA help?

OMMICATM was developed to measure methanol at between 20 and 300ppm in aqueous solutions, and between 2 and 150 ppm in oil. Dilution can be used to analyse higher concentrations of methanol using OMMICATM.  For further information regarding your specific concentrations, methods or suitable chemicals for dilution, please contact ommicasupport@luxassure.com.

How does the API of my oil affect my ability to use OMMICA?

OMMICATM has been tested and shown to work across a range of APIs from light condensates to heavy crudes.

OMMICA relies on readings of absorbance, will other components in my sample interfere?

OMMICATM Kits have a blank test incorporated within the procedure to avoid this problem.  Blanks are tested and compared with the samples to remove any of this ’background noise’ and give you full confidence in your results.  LUX Assure has undertaken intensive research into interference with the assay and may be able to comment on any potential interferences and ways to minimise these for your individual situation.

We already test for Methanol using GC, why would we want to switch now?

The OMMICATM method is simpler, quicker and more cost-effective – it doesn’t require complex oil extraction, specialist training or complex machinery with high running costs.  LUX Assure can provide all that is required, including kits, equipment and guidance, for non-specialist operators to achieve accurate results, from multiple samples simultaneously, in near real time.  Independent comparison testing has been carried out against GC and shows an excellent correlation.  Instead of throwing away time and money, sending samples onshore and waiting weeks for results, operators can be confident in the results obtained, so they can be used to make informed decisions, before the fluids arrive at destination.

I already have some laboratory equipment; can I use this with the OMMICA kits?

Potentially, yes.  For a full list of specifications for the equipment requirements please contact us, or refer to the equipment requirement guide for the relevant kit type.  If the equipment you have isn’t suitable, LUX can arrange sale or hire of any or all equipment required.

I don’t need to test that regularly, how long can I store my OMMICA kits for?

The reagents within the OMMICATM Methanol kits have a 6-month shelf life before you start to use them giving you plenty of time to use it even if you don’t test that regularly.

How many samples can I analyse at one time using OMMICA?

The reagents within an OMMICATM Methanol kit are allocated to make it simple to analyse samples in batches of 4, so you can use your OMMICATM kit in batches or all at once.  We understand that some users may wish to analyse smaller numbers of samples, to find out more about the possibility of single sample testing please contact duncan@luxassure.com.

I still have some questions, where can I find more information?

Monoethylene Glycol (MEG) Testing: Will OMMICATM work for me?

We need to measure high concentrations of MEG, can OMMICA help?

OMMICATM was developed to measure MEG at between 10 and 100ppm in both oil & water. Dilution can be used to analyse higher concentrations using OMMICATM.  For further information regarding your specific concentrations, methods or suitable chemicals for dilution, please contact ommicasupport@luxassure.com.

I don’t need to test that regularly, how long can I store my OMMICA kits for?

The reagents within the OMMICATM MEG kits have a 6-month shelf life before you start to use them and up to a month once the reagents within the kit are prepared for analysis, giving you plenty of time to use it even if you don’t test that regularly.

How many samples can I analyse at one time using OMMICA?

You can test anywhere between 1 and 7 MEG in Oil samples, or 1 and 14 MEG in Water samples from each kit at the same time, making it suitable for all frequencies and volumes of testing.

CoMicTM – Informing Better Corrosion Inhibitor Management

What does CoMic™ look for?

CoMic™ is designed to detect nanoscale aggregates of surfactant molecules, which are formed by many film-forming corrosion inhibitors above a certain concentration, the Critical Micelle Concentration (CMC).  These aggregates are called micelles.

How are micelles measured using CoMic™?

The presence of micelles is measured using proprietary fluorescence techniques.

When do micelles form?

Micelles are only formed when the critical micelle concentration (CMC) is reached.

What is the relevance of micelles and CMC to optimal corrosion rate?

There is a relationship between micellization and the adsorption of corrosion inhibitor onto metal (or at other interfaces), as well as maximum corrosion inhibition. 

Can CoMic™ be used to calculate the concentration of corrosion inhibitor present?

CoMic™ is a qualitative technique used to determine the presence of micelles to inform on optimal dosage rate, it is binary by nature and cannot be used to accurately determine the concentration of corrosion inhibitor.

How long will it take to analyse a sample?

Collecting data from a sample takes about 15 minutes, this data is then sent to LUX for processing. 

How is the data processed?

All the data is gathered by the field operator and then sent to LUX Assure for processing.  At present, the complex nature of the data processing makes it impractical to be done automatically on-site.

Are the chemicals used in the kit hazardous?

Care has been taken to ensure that the chemicals used are non-hazardous, where possible.  A small quantity of flammable solvent is used within one of the reagents, however, it is present in excepted quantities.  Let us know if you require copies of the Safety Data Sheets. 

Can I use CoMic™ to measure corrosion inhibitor in oil?

No, CoMic™ is designed to detect corrosion inhibitors in water.

You say that CoMic™ detects corrosion inhibitor in water. My samples also contain oil, will CoMic™ still work?

Yes, it is acceptable to have some oil present, and the water cut can be low. For example, CoMic™ has successfully tested 1-2% water cut on many occasions. However, water must be present as CoMic™ can only be used for oilfield fluids that contain free water. CoMic™ is an optical method so light needs to be able to pass through the sample. Where samples are significantly opaque a clean-up step can be introduced such as a short settling time, heating or centrifuging samples. We do not filter samples as this leads to corrosion inhibitor loss.

What is an acceptable corrosion inhibitor?

The corrosion inhibitor being used needs to be micelle forming. Typically, CoMic™ is suitable for water soluble, surfactant type corrosion inhibitors i.e. those containing quaternary amines, imidazolines and/or phosphate esters. We have found that the vast majority of such oilfield corrosion inhibitors are micelle forming and suitable for CoMic™ detection, nevertheless, LUX prefer that the chemical is tested with CoMic™ in advance of on-site use, to confirm micelle formation.

What are the steps in using CoMic™?

The following would be typical. Bold denotes work/support from LUX

  • Site identified
  • Safety data sheets sent to LUX for review
  • Chemical/fluid tested at LUX to confirm suitability
  • LUX will issue pre-deployment report so customer can confirm deployment
  • LUX train on-site personnel
  • Equipment and kits sent to site by LUX
  • Samples taken from system and taken to on-site lab by customer
  • Mixed with CoMic™ detection reagents
  • Placed in instrument
  • Data collected transmitted to LUX for data processing
  • Report provided by LUX
  • Customer compares data with other corrosion management tools to inform decisions e.g. coupons, probes, pump information

I have solids in my system. I understand this may influence micelle formation. Does it make CoMic™ unsuitable?

No, CoMic™ will still be suitable. Depending on the nature of the solids and the corrosion inhibitor it can become attached to the surface of the solid. The extent of this depends on the nature of the solids as well as the inhibitor itself. Where this is greater, the concentration of corrosion inhibitor in the bulk fluid will be reduced resulting in fewer micelles or no micelle formation if the inhibitor concentration is below the critical micelle concentration (CMC). This will be reflected in the CoMic™ signal detected so makes it ideal for such systems as the CoMic™ micelle.

I still have more questions, where can I find more information?
