Elastomers are essential additives in oil and gas cementing, providing enhanced mechanical properties and ensuring well integrity. One of the standout elastomer products in this field is Self-Seal, a self-sealing cement additive with remarkable capabilities.
Self-Seal is an innovative elastomer additive designed to spontaneously seal the cement sheath in response to hydrocarbon invasion. This unique feature ensures the maintenance of cement integrity by providing an auto-seal mechanism that activates upon contact with hydrocarbons. By doing so, Self-Seal prevents further cement fracture propagation, offering a robust solution to common cementing challenges.
A key advantage of Self-Seal is its ability to decrease the Young’s modulus of cement systems. This reduction imparts greater resilience to the cement sheath, enabling it to absorb hydrocarbon fluids effectively and stop the progression of fractures. Improving the mechanical properties of the cement is crucial for maintaining wellbore integrity, particularly in challenging drilling environments.
Self-Seal is highly versatile and can be utilised in a variety of cement designs across a wide range of densities and temperatures. This adaptability makes it a valuable additive for diverse cementing operations, ensuring optimal performance under various conditions. Whether dealing with high or low-density cement systems or operating in extreme temperatures, Self-Seal provides reliable sealing and mechanical enhancement.
The use of elastomer additives like Self-Seal in oil and gas cementing offers numerous benefits. These include improved cement mechanical properties, enhanced wellbore stability, and reduced risk of formation damage. Self-Seal’s ability to respond to hydrocarbon invasion by sealing the cement sheath ensures that any potential integrity issues are promptly addressed, maintaining the integrity of the well.
The integration of elastomer additives such as Self-Seal in oil and gas cementing operations represents a significant advancement in ensuring well integrity and operational efficiency. Their unique properties and proven effectiveness make them invaluable assets in enhancing the mechanical properties of cement and providing robust solutions to common cementing challenges.

Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
