Sour gases containing hydrogen sulfide/sulfide (H2S) can have a very adverse effect on elastomers. The elasticity that is not resistant to corrosion becomes hard and brittle, losing elasticity and sealing ability, ultimately leading to sealing failure. JST has developed various sour gas resistant elastomer materials for the oil, natural gas, and petrochemical processing industries with the third-p...
Packer Elements are elastomeric components designed to be used between sections of oil and gas production tubing, providing superior sealing and isolation capabilities. Made of high-quality rubber material such as NBR, HNBR and Aflas, the packer element provides superior sealing performance, ensuring maximum well integrity and efficient production. Designed for challenging downhole environments, P...
Packer elements are components used in oil and gas well completion operations to isolate different zones of the wellbore. The design factors of packer elements include: Material Selection: The choice of material for the packer element is critical to its design. It needs to be able to withstand the downhole conditions, such as high temperatures, pressures, and corrosive fluids. Common materials use...
Well completion is the process of making a well ready for production after drilling. As in well drilling, seals used in well completion have to cope with the increasingly harsher conditions of deeper wells and diverse geographical areas, from the heat of Africa to the cold of Canada, Norway or Russia, with storage conditions as low as to -60℃. The system pressure can vary from 345 bar to 2070 bar,...
We are thrilled to introduce the new HNBR packer element which is made of HNBR 85 Shore A, and this rubber material is especially developed for packer element. The HNBR element passed customer’s test. The HNBR Rubber Packer Element is designed for downhole completions, where it serves as a critical component in isolating different zones within the wellbore. It is engineered using high-quality hydr...
Oil well production is the most important stage in the lifespan of oil wells, which prepares oil or natural gas for final treatment by releasing hydrocarbons. Separation is usually carried out on the seabed, rather than on the platform of offshore oil wells. In addition to dealing with system pressures up to 1,380 bar (20,000 PSI) and temperatures exceeding 900C(1,650F) in flare stack controls, se...
Every machine or system that relies on seals understands the seriousness of a leak or premature seal failure. The subject involves significant financial, operational, and sometimes environmental issues that require in-depth understanding. The Basics of Seal Leakage What is Seal Leakage?: Beyond the basic definition, seal leakage can be understood as any unintended escape of fluid or gas due to the...
