Oil Field Extraction - Oil Exploration - Fuels

Oil exploration and extraction presents very challenging conditions for Elastomeric seals; a combination of extreme temperatures, aggressive chemicals and gases, abrasive media, high pressure and destructive forces, subject seals to the harshest environments in the world.

In addition, the techniques employed to exploit reserves are becoming more complex  with operations moving to more remote locations and deeper well depths, extending the operating demands on the seals even further.

Marco Rubber and Plastics offers a wide variety of products and materials to meet the need of our customers in the Oil field and gas, Marco Rubber understands the nature of high pressure high temperature environments associated with Oil and Gas exploration and transportation.

Marco has developed an extensive line of Markez Perfluoroelastomers dedicated to our Oilfield and Gas customers. Markez is similar to Kalrez® and Chemraz® at significant cost savings and custom O-ring sizes are supplied without additional tooling or setup charges.

Explosive Decompression

Explosive Decompression (ED), also referred to as Rapid Gas Decompression (RGD), is a failure mechanism of elastomer seals that is due to the rapid decompression of gaseous media. When elastomer seals are exposed to high-pressure gas for a prolonged period the gas permeates into the seal material. When the external pressure is reduced, the gas which is dissolved within the seal material comes out of solution to form micro bubbles. As the gas expands, it may permeate out of the seal material. However, if the rate of decompression (and hence expansion) is high, gas which is trapped within the seal can cause fissuring and resut in seal failure. Marco Rubber offers several materials to prevent this Phenomena and minimize its effects, please refer to the chart below.

Typical Product:

  • O-rings
  • X-rings
  • V-rings and Packings
  • Custom Gaskets
  • Back-up rings
  • PTFE seals and O-rings
  • SES spring energized seals
  • Cap Seals

Common Application Environments:

  • AED (Anti Explosive decompression) materials in FFKM (Markez®), FKM (like Viton ®), Aflas® and HNBR
  • H2S (Hydrogen Sulfide) Sour gas and Methanol resistant materials
  • Low temperature capability
  • Ultra high temperature materials

The temperature ranges presented above are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.
