Rheoplus rheological additives are commonly used in water-based drilling fluids for saltwater drilling operations:
Easily dispersible rheology modifier made from high purity micronized sepiolite clay for waterborne systems, providing thixotropic effect, high viscosity, as well as anti-settling and syneresis control to the system. It is completely unaffected by electrolytes present in the system.
Easily dispersible rheology modifier made from high purity micronized attapulgite clay, which acts in water-based systems, providing thixotropic effect, as well as anti-sedimentation and syneresis control to the system. It is not affected by the electrolytes present in the system.
Sepiolites and attapulgites are exceptionally resistant to the presence of salts and cations in saline media. Unlike other rheological additives, such as bentonites, sepiolites and attapulgites maintain their rheological properties in the presence of high concentrations of salts.
Sepiolites and attapulgites offer excellent thermal stability under extreme temperature conditions, which is crucial in drilling operations where thermal changes are common.
These additives allow for precise control of the viscosity of the drilling fluid, which is essential to ensure its ability to transport drill cuttings and maintain process efficiency.
Sepiolites and attapulgites form a three-dimensional gel structure in drilling fluids that helps prevent solids from seeping into the rock formation. This is especially valuable in operations where you are looking to maintain the integrity of the formation and prevent damage.
Drilling fluids with sepiolites and attapulgites offer a greater ability to form bridges and seals in the rock formation, reducing the loss of fluid circulation to the formation and improving the efficiency of the operation.
Sepiolites in particular, possess the ability to suspend particles even in media with low pH levels. This is essential in operations where suspension of drill cuttings needs to be maintained in acidic conditions.
The use of sepiolites and attapulgites in drilling fluid additives offers a number of key benefits, such as salt media tolerance, thermal stability, viscosity control, filtration prevention, and suspension capability in challenging conditions. These properties contribute significantly to the efficiency and success of drilling operations in harsh environments.
