RGD, or rapid gas decompression, occurs when absorbed gases expand suddenly upon pressure drop. HPHT conditions amplify this risk, leading to seal blistering or rupture. Resistant seals use specialized compounds like HNBR or fluorocarbons to mitigate gas permeation. In high-pressure high-temperature drilling, these seals protect equipment from catastrophic failures. They undergo rigor... https://globalsealstech.com/oil-gas-seals/
