Application of PCIU for protection of emergency pipelines against corrosion

Abstract

The field pipelines at the Samotlor field are the main means of oil and gas transportation. Corrosion causes premature wear of pipes and piping equipment and can cause breakdowns. To prevent emergencies, it is necessary to carry out repair and technical work timely, using chemical dosing units. To protect the field pipelines at the Samotlor field, stationary reagent dosing units are used. All of them are installed at well pads, closer to automated group metering units. They have a number of significant disadvantages: difficulty in installing; difficulty of the repair work; impossibility to remotely control the process of pumping a chemical reagent in real time; long idle time; outdated security system. A modern solution to the listed above problems for the oil and gas industry is the use of portable chemical injection units (PCIU). A PCIU is a state-of-the-art trailer-based system, and it can also be installed permanently on a well pad. The advantage of this installation is its high mobility, ease of installing, minimal installation and maintenance costs, the ability to automate.
