Sweeping agents are essential in oil and gas drilling to ensure efficient hole cleaning and maintain wellbore integrity. Among the leading sweeping agents, Strata Kleen® stands out for its superior performance in transporting drill cuttings, metal shavings, and other debris out of the wellbore.
Strata Kleen® is a treated polymerised synthetic fiber designed to enhance the carrying capacity of drilling fluids. It is compatible with all drilling fluids and disperses easily, making it a versatile and efficient hole-cleaning agent. Strata Kleen® loosens and removes cuttings beds and lifts and carries metal shavings and debris during milling operations.
One of the primary advantages of Strata Kleen® is its ability to mix faster than traditional gel/polymer sweeps. It can be easily mixed through rig mud-mixing hoppers and removed by shaker screens, ensuring a streamlined cleaning process. Effective hole cleaning reduces torque and drag, which enhances the rate of penetration (ROP) and minimises the need for wiper trips.
Strata Kleen® is non-toxic and has no effect on the fluid LC50, making it safe for use in various drilling environments. It is chemically inert and non-fermenting, ensuring it does not affect the overall fluid viscosity. Additionally, when mixed as recommended, it will not plug measurement-while-drilling (MWD) tools or mud motors.
Strata Kleen® replaces the use of high viscous and weighted hole cleaning sweeps, making it highly effective in vertical, directional, and horizontal wells without increasing drilling fluid viscosity, weight, or solids. It is particularly beneficial in milling operations, where it efficiently cleans very fine metal debris.
Good hole cleaning is crucial for reducing torque and drag, and Strata Kleen® excels in this regard. By enhancing the ROP and reducing the frequency of wiper trips, it contributes to more efficient drilling operations. The sweeping agent’s ability to lift and carry debris ensures that the wellbore remains clean, supporting smooth and continuous drilling.
Strata Kleen® represents a significant advancement in sweeping agent technology for oil and gas drilling. Its unique properties and proven effectiveness make it an invaluable asset in maintaining wellbore integrity and enhancing drilling efficiency across various well types and drilling conditions.

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.
