Journal Article
HASSANI, F., FAISAL, N.H., NISH, R., ROTHNIE, S. and NJUGUNA, J. 2022. The impact of thermal ageing on sealing performance of HNBR packing elements in downhole installations in oilfield wellhead applications. Journal of petroleum science and engineering [online], 208(part B), article 109200. Available from: https://doi.org/10.1016/j.petrol.2021.109200

Hydrogenated nitrile butyl rubber (HNBR) elastomers are highly resistant to chemicals and degradation, and they are good candidates to be adopted in aggressive environmental conditions of high temperature and pressure. As these service parameters are... Read More about The impact of thermal ageing on sealing performance of HNBR packing elements in downhole installations in oilfield wellhead applications..
