... in the oil and gas industry causes well integrity issues totaling billions of dollars annually. Consequently, it is intuitive to include corrosion inhibitors in well treatments which are corrosive in nature to protect our equipment. Corrosion inhibitors are molecules that can stick and create an impermeable...

... and changes in fluid properties and conditions that warrant mitigation by chemicals. The plan was to inject corrosion inhibitor at the start of the pilot and switch to a corrosion/asphaltene combo chemical with CO 2 break-through, as it tends to destabilize asphaltene and lead to deposition. Once water cut...

..., defoamer, and demulsifier were tested for compatibility with production chemicals such scale inhibitor, corrosion inhibitor, and biocide, neither precipitation nor separation was seen. The recently developed foam chemical may help to further reduce corrosion from 0.17 mm/y to 0.05 mm/y. The technical...

... Abstract Critical micelle concentration (CMC) is a known indicator for surfactants such as corrosion inhibitors ability to partition from two phase systems such as oil and water. Most corrosion inhibitors are surface active and at critical micelle concentration, the chemical is partitioned...
