I think that it’s a good check for the field or a lab doing methanol in oil analyses to understand export oil quality.
At LUX Assure we work with many of the world’s leading oil and gas companies, as well as a long list of third-party contractors and operators in offshore, sub sea and onshore services.
Statoil has tested CoMic™ in our corrosion lab in Porsgrunn to evaluate if the technology could be used in our fields. Four different corrosion inhibitors were analysed by CoMic to find the CMC for each inhibitor. Residual corrosion inhibitor concentration was used to find the actual corrosion inhibitor concentration at CMC. In parallel corrosion tests were carried out to find the optimum inhibitor concentration for corrosion protection. The CoMic™ analysis and the corrosion tests gave the same optimal inhibitor concentration for each of the inhibitors even if the concentration was different for the different products (30, 30, 50 and 120 ppm). Based on these results CoMic™ is evaluated as a good tool for optimization of corrosion inhibitor concentration in the field and is recommended to be used in several of our fields.
To evaluate the new colorimetric method, both methods (the GC and the LUX method) were used to analyze a series of blind samples. The results show that the LUX method is as accurate as the GC method while using equipment that is less expensive and much easier to operate and maintain.
