  • For downhole sealing application in the oil and gas industry. Acrylonitrile Butadiene Rubber (NBR) and Hydrogenated Acrylonitrile Butadiene Rubber (HNBR) have been widely used in many products. The oil and gas industry needs a reliable methodology to develop operation envelopes for elastomer sealing elements deployed in various service tools. In most cases, the estimated operation envelope relies on laboratory-style compatibility tests along with life prediction models. The conventional elastomer compatibility test is based on industry standards, ISO 23936-2:2011(E). To build a practical operation envelope for NBR/HNBR in harsh environments, it is required to fill the gap between laboratory-scale tests based on ISO 23936-2 and field operation experience on how NBR and HNBR behave in such conditions. This paper covers the literature review on the effect of Hydrogen Sulfide (H2S) on NBR/ HNBR. Then, experimental works under various conditions similar to field operation for downhole service were carried out. Controlled laboratory elastomer tests and mechanical tests for retrieved packer samples from field operations were studied. Operation envelope and material degradation mechanism were developed based on the results from mechanical tests and chemical analysis.
