Water Survey Assesses Souring and Corrosion at Production/Injection Plant
At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective.
Artificial Pipeline Model Enables Comparison of Biocides in a Dynamic System
To facilitate testing and comparison of products that attenuate microbially influenced corrosion under field conditions, a method using microorganisms from a low-tide, anoxic North Sea sample was developed that allows corrosion measurements to be made for corroding biofilms grown on steel surfaces.
Can Robots Improve Above-Water Riser Inspections?
The criticality of above-water riser hull piping requires frequent inspections. Traditional manual inspection methods present safety and efficiency concerns, but work is being done to see if robotic technologies—such as drones and crawlers—can do the job as good as, or even better than, humans.
