Wellbore stabilisers are crucial for maintaining the integrity and stability of the wellbore in oil and gas drilling operations. They help prevent lost circulation, control seepage, and enhance the overall stability of the borehole. Three notable wellbore stabilisers are Strata Flex®, Vanguard®, and WBS-2000, each offering unique benefits for challenging drilling conditions.
Strata Flex® is an elastomeric sealant specifically developed to improve wellbore stability in the most challenging formations. It is a unique blend of inert, resilient, and malleable particles designed to form an optimal seal in the fractures of depleted and weak formations. This sealant effectively stabilises the wellbore, preventing fluid loss and enhancing drilling efficiency.
Vanguard® is a multi-purpose blend of specifically sized particulates developed to prevent lost circulation effectively. It easily mixes with all drilling fluids and is recommended for sealing severe to total loss situations. Vanguard®’s versatility and ease of use make it an essential component in drilling operations where lost circulation is a significant concern. By providing a robust seal, Vanguard® helps maintain wellbore integrity and prevent costly delays.
WBS-2000 is a wellbore stabiliser composed of a blend of cellulose-based products and polymers. It is designed to improve borehole stability by enhancing invasion control, seepage loss, and other loss control circumstances. WBS-2000 produces a tight, thin wall cake that generates a fast, effective seal, minimising invasion and strengthening the wellbore. This stabiliser is particularly effective in maintaining wellbore stability in various formations, ensuring smooth and efficient drilling operations.
The use of wellbore stabilisers like Strata Flex®, Vanguard®, and WBS-2000 offers numerous benefits, including improved wellbore stability, reduced fluid loss, and enhanced drilling efficiency. These stabilisers help prevent lost circulation, control seepage, and strengthen the wellbore, making them invaluable in challenging drilling environments.
Strata Flex® provides exceptional sealing in fractures of depleted and weak formations, Vanguard® effectively prevents lost circulation in severe to total loss situations, and WBS-2000 offers comprehensive wellbore stability by improving invasion control and seepage loss. Together, these wellbore stabilisers enhance the integrity of the wellbore, reduce operational risks, and contribute to the overall success of drilling operations.
The integration of wellbore stabilisers such as Strata Flex®, Vanguard®, and WBS-2000 in oil and gas drilling operations represents a significant advancement in maintaining wellbore integrity and ensuring efficient and safe drilling processes. Their unique properties and proven effectiveness make them essential tools in modern drilling practices.

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.
