In drilling operations, the drilling fluid passes through high pressure and temperature. During use, the drilling fluid circulates and flows in the annulus between the wellbore wall and the drill pipe, spraying out from the drill bit to clean the bottom of the well and carrying rock cuttings out of the well. A significant portion of fluid loss happens throughout this operation for various reasons. A filtrate reducer is an additive for filtration control that can form a filter cake at the wellbore wall to reduce fluid loss and protect the underground environment. The filtration performance of drilling fluid has an essential impact on reservoir protection and wellbore stability. Therefore, filtration control is an important property of drilling fluid, particularly when drilling through permeable formations, where hydrostatic pressure exceeds the formation pressure.

It is vital for drilling fluid to form a filter cake, which effectively minimizes fluid loss quickly. Several methods have been used to prevent the loss of a circulation fluid. Some methods use fibrous, flaky, or granular materials to plug the pores as the particulate material settles out of the slurry. Commonly used filtrate reducers are starch derivatives, cellulose, lignite resin, polyacrylic acid, and artificially synthesized multi-copolymers. However, due to the harsh underground environment, such as high temperature, salinity, and pressure, and the sophisticated structure formed in deep wells, some conventional additives are challenging to fulfill desired functional requirements, such as maintaining colloidal stability due to low chemical and physical stability. At Centum, scientists and engineers have custom-formulated and designed the most effective additive blend to address this issue.

FiltraGuard

After years of research and innovation, scientists at Centum realized the importance of developing a novel multifunctional filtrate reducer additive blend with high physical, chemical, and thermal stability and salt tolerance. Developing low-molecular-weight filtrate reducers with high-temperature resistance is essential to address the challenges in regulating the rheology and filtration performance of high-density drilling fluids at high temperatures. Centum’s FiltraGuard is a signature additive blend used as a filtrate reducer during onshore and offshore deep drilling operations. It offers the ultimate performance during challenging drilling operations and helps to save operation costs significantly. FiltraGuard is a sustainable, ultra-performing additive blend designed to meet ESG targets. All the additives in the formulation are locally sourced and offer ultimate quality. At Centum, we custom engineer FiltraGuard to meet specific drilling operation needs.
