MATERIAL / ELASTOMER SELECTION

Material Selection
 

IEG offers various material configurations depending on well conditions. IEG highly trained
engineers are able to assist you in the selection of the most cost effective metal and polymer required.


The following guidelines are used in selection of metals for our packers and related tools:

  • Standard, non-corrosive - Low alloy steels (e.e AISI 4140) with mechanical properties compatible to API P110 tubulars.

  • Non-corrosive service containing H2S - Low alloy steels ( AISI 1040) with mechanicalproperties compatible to API L80 tubulars.

  • Corrosive service with little or no H2S - (9 Cr, 13Cr,17-4PH, alloy 450, Super 13Cr)
    with mechanical properties that vary from 80ksi to 110ksi minimum yield strength.
    The selection depends on the service environment (PH, Chrorides, temperature,H2S etc.) and strength requirement.

  • Severely corrosive Co2 and H2S - Nickel alloy such as Incoloy 825, 925 and 718 at
    strength of 110ksi minimum yield strength or higher. For equipment requiredfor temporary function and then allowing for quick removal by drilling or milling an additional group of materials are used:

    • Cast iron

    • Composite reinforced polymer

In addition to the above, IEG can provide tools of other materials through our experiences and extensive network of raw materials suppliers.

Elastomer Selection

 

Steel provide the strength needed in a tool but seal materials provide the crucial sealing and isolation of the pressure zones. Ideally it should be inexpensive, high strength and resilient to last throughout the life of the well or the intended duration. In addition to polymer, we have the technology to design and build metal-to-metal faced seal system.


Choosing the most appropriate seal requires a knowledge of the application and downhole conditions.
 

Compiled below is basic guideline of the type of seals and it's application. Our engineers are trained to assist in the selection for conditions outside of these guidelines.
