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.
Product and customer insights
CHALLENGE A 40-hectare raw water storage dam had persistent issues with blue-green algae (BGA) blooms, leading to taste and odor problems. Despite the presence of an aeration system to address water stratification and mixing, BGA counts remained seasonally high, particularly in summer and autumn. Upgraded aeration in 2018 did not resolve the issue, leaving the […]
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.
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
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.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
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 East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
