CONTRACT MEASUREMENTS
In our service laboratory we offer extensive third-party contract measurements in the area of Flow Assurance, crude and live oil, petroleum and petroleum products like oilfield chemicals, inhibitors, gas hydrates and testing of physical properties.
The analysis of the deposition behavior of water and their scale inhibitors or preventers in pipeline systems such as industrial plants of the petroleum industry, via food industry and geothermal energy complete our offer.
For this we adapt the test parameter to your needs and provice test facilities beyond the typical standard procedures.
Customer specific adaptations of our instruments and completely new test set-ups are possible.
