The Oilfield packer element, usually is the rubber sealing product with cylinder shape which is used in layered mining, testing, water injection, acidification and fracturing in oil field. According to the mode of use, it can be divided into expansion packer element and compression packer element. JST offers elements in a variety of oilfield suitable materials including materials for high pressure...

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...

Finite element analysis (FEA) is a computer-based technique used to calculate the performance of components in practical applications. This advanced technology can determine how components are affected by extreme temperatures and pressures, specific stresses, and aggressive chemical environments. Proficient use of FEA simulations enables accurate modeling by predicting behavior, eliminating the ne...

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...
