TriMAX™: Next Generation Deepwater Drilling Fluid


QMax’s next generation deepwater drilling fluid, TriMAX, goes beyond today’s typical flat rheology by providing 3D engineered drilling fluid rheology downhole. Traditional flat rheology mud systems focus on providing fluid rheology that remains essentially unchanged, regardless of the widespread temperatures generally seen within deepwater wells. Drilling fluid rheology is only measured at ambient pressure, therefore ignoring the impact downhole pressure and formation temperature has on the fluid properties.

TriMAX delivers performance and engineered optimal rheology downhole, where it has the most impact. Through 3D control, TriMAX provides drilling performance with effective hole cleaning and increased rates of penetration, while minimizing equivalent circulating densities by reducing the progression of low shear rate yield point of the fluid under downhole conditions. In combination with our MAXSITE hydraulics software simulations, the TriMAX system allows QMax to engineer and maintain the proper drilling fluids for individual wells, ensuring downhole control of the equivalent circulating density and equivalent static density. This greatly enhances the possibility of induced mud losses to formation or kicks.
