Compatibility Study of HDPE Internal Lining in Carbon Steels for Polymer Injection and Mixing Applications

Oil and gas production consider the nature of the reservoir and the complexity of the forming layers as a governing factor. One of the major challenges that are faced in the oil and gas upstream industry is the complexity of the reservoir in which the production requires enhanced recovery process. Polymer injection is one of the methods that is used widely to enhance the production and increase it accordingly. However, after the polymer preparation and mixing process, a system of flowlines and pipelines is utilized to carry over the final polymer product to the injection wells. This requires a comprehensive study of the material selection options for the pipelines and flowlines that are considered based on their performance, low maintenance requirement, and cost effectiveness. This paper focuses on the testing and qualification of high-density polyethylene (HDPE) internal lined carbon steel that is considered as one of the material selection options for polymer transfer. Further, material selection options are discussed along with the testing and qualification requirements. Compatibility of the high concentrated polymer liquid with HDPE material was tested to design HDPE liner inside CS pipes to transport and inject the polymer into the wells.
