Delivers Improved Elasticity and Tensile Strength

The DosDur™ Flexible Cementing Solution provides elastic properties, and fracture toughness of the cement bond including excellent mechanical properties of set cement system with high thermal stability up to 320 oC.

The DosDur™ cementing solution was developed with high design flexibility to take elastic cement systems out of the lab and into the real world. DosDur™ cementing solution are designed to isolate and protect your targeted zone for the life of the well. DosDur™ deliver assured long-term zonal isolation for your specific well challenges.

Providing Zonal Isolation For a Well Life Cycle

______________

Once the wellbore has been properly conditioned, a cement slurry is chosen that is most suitable for the known well conditions and anticipated challenges, in order to ensure long-term isolation. DosDur™ powder can be formulated readily with Hallow Glass bubbles in low density slurries to provide predicted Compressive strength, Tensile strength, and Young Modulus values to the simulated ones.

Application & Features

  • Wells exposed to high-pressure fracturing operations
  • Harsh environment (high temperature & pressure)
  • Self cure crack and microannuli  in Hydrocarbon and gas environment
Benefits

  • Get superior durability during pressure and thermal cycles
  • Gain enhanced mechanical properties with good reliability
  • Gain enhanced tensile strength and elasticity for improved long-term zonal isolation

Suitable for Anticipated Challenges

DosDur™ Flexible Cementing Solution expands after setting, improving cement bonding and sealing microannuli that can cause unwanted gas migration. A low Young’s modulus enables it to withstand cement sheath stresses (due to drilling, perforating, injection, hydraulic fracturing, underground gas storage, and changes in temperature, pressure, or both).

 

 

Product Name Description
DosDur™ Cement Light Filler The product is utilized as a seepage loss control additive in downhole cementing applications and acts as a crack prevention additive.
DosFlex™ 100 Elasticity Agent To make set cement matrix having flexible mechanical properties at low or medium temperatures, DosFlex™ 100 is required.
DosFlex™ 300 Elasticity Agent DosFlex™ 300 Elasticity Agent is a chemical that is formulated with engineering particle size slurry to provide the set cement matrix with flexible mechanical properties at high temperature.

Greater Efficiency and Reliability

DosDur™ Flexible Cementing Solution withstands stresses induced by high injection pressures, and temperature fluctuations.

Highest-quality cement job in less time and with minimal risk can be achieved due to the high stability of the product. TGA analysis of DosDur™ Flexible Cementing Solution shows high stability of the product for up to 380 °C.
