Nitrogen production and injection is a measure for an oilfield to increase its production.

In Tahe Oilfield, located in Xinjiang, China, Kerui Petroleum Equipment Co Ltd, said that its overall success rate of nitrogen injection for production improvement was more than 95 per cent and its cumulative production increment was 100,000 tonnes.

According to the features of vuggy carbonate reservoirs at deep layers in Tahe oilfield, the company adopted its self-developed three-time oil recovery technique based on injection of nitrogen into vuggy reservoirs, and completed the operation of air injection for 115 wells. In operation, while successfully overcoming the challenge of nitrogen injection for wells with the depth of over 7,000 metres, Kerui Petroleum Equipment Co Ltd, again, verified the high quality and high efficiency of the nitrogen production equipment with an output pressure of 70 MPa, which was independently developed and manufactured by Kerui oilfield services.

A Kerui oilfield services source said, “Kerui’s membrane separation technique for nitrogen production is one of the core techniques of Kerui oilfield services. Up until now, Kerui has successfully applied for over ten inventions and new applied patents based on this technique.

“As the largest nitrogen production equipment manufacturer and service provider, and with more than 60 teams to provide nitrogen production engineering services, It has provided various technical services, which are customised for nitrogen production, to CNPC, Sinopec, CNOOC and other oil giants in China. Now, Kerui’s share in the Chinese nitrogen production market is 85 per cent.”

According to the firm, Kerui Petroleum Equipment Co Ltd has been working hard to make technical innovations and to improve its technical capacity. It also strived to create constant value and high-level services for its customers, by upholding the principle of ‘customer first and market oriented’.
