The polymer is a tough tear resistant high strength elastomer with a tensile strength exceeding 5000 psi...

...Introduction In the oil field, especially in subsea applications, it is of great importance for elastomer sealing components for BOPs and wellheads to meet the pressure and temperature rating under newly released API standards such as API 16A (fourth edition) and API 6A (twenty-first edition...

... and qualitative analysis was performed to determine if the miscible gas mixture damaged the structure or compromised the capability of the elastomer / swellable packer to hold pressure. Two packers were swollen (separate fixtures) in diesel under conditions similar to downhole pressure and temperature. The test...

... in high-temperature wellbore fluids as well as degrade in them. Additionally, traditional metal foundry and polymer fabrication methods need to be used to fabricate the metal and elastomeric materials to maintain high reliability, acceptable costs, and high product consistency. Dissolvable Elastomer...

... sealed completely whenever new elastomers were in place. Since the WRT is intended as a single-use tool this did not cause concern. Tests were conducted over a wide range of pressures so that seal performance could be evaluated as the pressure was increased or decreased. The elastomeric prototype design...

... is a practical method to measure the 10 OTC-27609-MS sealing performance of elastomers in a complex downhole environment (Xiaobin 2016). The test enables an understanding of the effect of temperature on the sealing force and stiffness of elastomeric material in an aggressive fluid environment, and helps...
